Hurricanes can be up to 600 miles wide with winds spiraling inward at 75-200 mph. Unlike extropical cyclones, hurricanes have warm air at their center. The worst hurricane was Hurricane Andrew in 1992, which started in the Atlantic and hit the Bahamas and Florida with winds up to 175 mph, crossing Florida before strengthening over the Gulf of Mexico. The eye of the hurricane is the calmest part in the center with light winds and no rain.

Hurricanes!!
Hurricanes form over warm tropical waters when cold and warm air masses collide, creating a large rotating storm with heavy winds and rain that can cause extensive damage as it makes landfall. They typically include an eye and surrounding rain bands and can spawn tornadoes, leaving many homeless or injured as seen with Hurricane Hugo, a category 5 storm that hit South Carolina in 1989, lasting over 4 hours and leaving 50,000 people homeless and multiple injuries.
Cyclones,quentin
Cyclones are the most destructive storms in the world. Typhoon Tip, which occurred in the Pacific in 1979, remains the largest and most intense tropical cyclone ever recorded. Cyclones form from clusters of strong thunderstorms and have an eye surrounded by an eyewall that is the calmest area with low pressure and no rain. They are most common in ocean regions like the Pacific, where around 15 occur each year, and can cause major economic damage, like Hurricane Katrina which cost nearly $1 billion.
Natural Disasters: A comprehensive Presentation
Natural disasters can be categorized as meteorological, geological, or hydrological based on their cause. Meteorological disasters include hurricanes, typhoons, cyclones, tornadoes, and are caused by atmospheric conditions; they typically involve strong winds and rain. Geological disasters are earthquakes and volcanic eruptions caused by movements of tectonic plates deep below the Earth's surface. Hydrological disasters refer to tsunamis and floods caused by water, such as tsunamis triggered by undersea earthquakes or severe rainstorms causing floods. The document provides examples of different types of natural disasters, how and where they typically occur.

Tsunamis are large waves generated by earthquakes or other disturbances that displace large volumes of water. They can reach beaches in minutes and cause extensive damage. A major 2004 tsunami in Sri Lanka killed over 40,000 people after an earthquake in the Indian Ocean. Hurricanes are violent tropical storms with winds over 74 mph that form over warm ocean waters and move westward. They can only be stopped by land or cooler waters. Floods occur when water overflows river banks or other areas, often due to heavy rain or snowmelt, and can cause billions in damage annually in the US. Drought is a period of unusually dry weather lacking precipitation that can last years and seriously damage crops and water supplies. Tornado
A natural disaster
Hurricanes form over warm tropical oceans in late summer and early autumn when heat and moisture are present. They can cause extensive damage through strong winds, heavy rainfall, floods, landslides and sometimes tornadoes. Hurricane Katrina in 2005 was especially devastating, killing many people in New Orleans and forcing hundreds of thousands to evacuate. Accurate hurricane forecasts from the National Hurricane Center help people prepare by issuing watches and warnings ahead of landfall.

Natural disasters
This document discusses different natural disasters and focuses on tsunamis. It states that tsunamis can be caused by volcanoes, earthquakes, or landslides underwater. For volcanoes, an eruption under the sea can break pieces of the volcano that fall into the water and cause pressure increases that result in huge waves. Earthquakes beneath the ocean floor can also displace water and slowly generate enormous tsunami waves. Landslides into bodies of water function similarly by adding pressure from displaced material, forcing water upwards and creating gigantic waves.
Natural disasters
This document discusses various types of natural disasters including tornadoes, hurricanes, earthquakes, volcanoes, floods, tsunamis, winter storms, and wildfires. For each type of disaster, it provides a brief definition and examples of past events. It also includes sections with safety tips and advice on preparing for each disaster, such as creating a disaster supply kit and developing a family disaster plan. The document encourages readers to learn more about specific disasters that interest them in order to better protect themselves and their families.

Natural disasters ppt by muzzammil ghayas
This document provides information about different types of natural disasters including those that occur on land, in water, and in air. It discusses disasters such as earthquakes, volcanic eruptions, floods, tsunamis, tornadoes, and others. It describes their causes and effects, highlighting that while natural disasters cannot be controlled, understanding them better can help minimize damage through improved disaster management.
tornados
Tornadoes are rapidly spinning funnel clouds that reach from thunderstorm clouds to the ground, causing mass destruction with winds that can send cars flying and destroy homes and buildings. They form when hot and cold air masses collide and start circulating intensely, with the force eventually producing a funnel. Some of the most destructive tornadoes include the 1953 Flint Beecher tornado in Michigan, which killed over 100 people and injured 900 with 100 mph winds that destroyed 20 homes.
Thunderstorm1
Thunderstorms are storms produced by cumulonimbus clouds that contain lightning and thunder. They most commonly occur in the southeastern and midwestern United States between March and June. Thunderstorms can cause dangerous flooding, winds, hail, and lightning. It is important to prepare a disaster kit and seek shelter indoors during storms to stay safe from potential damages and loss of life.
Hurricanes
Tropical cyclones are rotating storms that form over warm ocean waters and are called hurricanes in the Atlantic and eastern Pacific. They have very strong winds that spiral inward toward the eye, where winds are light and skies are clear. The strongest winds and heaviest rains occur in the eyewall that surrounds the eye. Hurricanes are categorized on a scale of 1 to 5 based on their wind speeds, with category 3 or higher considered major hurricanes that can cause extensive damage. Climate change is expected to increase hurricane intensity by raising ocean temperatures.
Do we need tax all aspects of Pollution?
This document discusses pollution and the debate around putting a price on carbon emissions. It provides background on the author and defines pollution. Several countries and regions are identified as having some of the worst air and water quality problems. While some funds have been pledged internationally for climate change, there is a lack of oversight on how the money is being spent. The author argues that a carbon tax alone will not significantly help the environment since it only increases costs for consumers without addressing major polluters. Overall pollution is not a new issue but past efforts to increase environmental awareness through media are noted.
Nature fury
The document summarizes a presentation on natural disasters titled "Nature's Fury". It discusses different types of natural hazards like earthquakes, tsunamis, hurricanes, floods and cloud bursting. It specifically focuses on the 2013 Uttarakhand floods caused by heavy rainfall and glacier melting. Over 8,000 people died in the floods, 10,000 were injured and 30,000 were stranded in the valleys. The floods damaged over 1,500 roads, 154 bridges and destroyed more than 2,200 houses. While natural factors contributed, the document also attributes man-made causes like tourism, deforestation, and lack of disaster management to the floods. It calls for better land use policies and use of technology to
Tornadoes
Tornadoes are powerful rotating columns of air that form during severe thunderstorms. They most commonly occur in a region of the central United States known as "Tornado Alley". Tornadoes can cause extensive damage by killing and injuring people, destroying property, and removing soil. While tornado watches and warnings aim to protect lives, the unpredictability of tornadoes makes them difficult to fully prepare for or prevent. More advanced prediction systems and continued research on tornado formation and impacts could help mitigate their damage.
Extreme weather
The document discusses various types of extreme weather events including hurricanes, tornadoes, blizzards, floods, and droughts. It provides details on the formation of hurricanes over warm ocean waters and specifics on major hurricanes like Andrew and Katrina. Tornadoes are described as powerful funnel clouds caused by colliding warm and cool air masses. The document also outlines significant blizzards, floods and droughts that have caused major damage and billions of dollars in losses across the United States.
What Do We Do About Natural Disasters?
The document discusses natural disasters and strategies for addressing them. It presents a spectrum showing the probability and severity of different types of emergencies. Maps show hazards from earthquakes, volcanoes, wildfires, and hurricanes in the US. Examples demonstrate impacts from coastal change, hurricanes, and storm surge. Lessons learned questions focus on which hazards to address, conveying science, presenting vulnerability, future implications, and responsibility.
Weather Hurricane
Hurricanes form over warm tropical oceans where the sea surface temperature exceeds 27 degrees Celsius. They tend to occur in late summer and early autumn when ocean temperatures are warmest. Global warming may be increasing ocean temperatures and making hurricanes more common and severe. Hurricane Katrina formed over the warm Gulf of Mexico in late August 2005, intensifying to a Category 5 storm before causing catastrophic damage when it made landfall in New Orleans. With winds over 150 mph and a 25-foot storm surge, Katrina was the costliest hurricane in U.S. history, causing nearly $75 billion in damage.
Hurricanes slide show
The document discusses how hurricanes form and their life cycle. It explains that hurricanes form over warm ocean waters when a low pressure system develops and causes warm air to rise, condense into water droplets, and continue rising, creating extreme winds. It describes the four stages of a hurricane's life cycle: formation, prematurity, full maturity, and decay. Hurricanes typically decay when moving over land or cooler waters due to a less favorable environment.
Natural disasters powerpoint
A tsunami is a series of huge waves generated by earthquakes or volcanic eruptions that can reach heights of 30 meters, travel as fast as jets, and go 1.25 miles inland. Mudslides are fast moving landslides of mud caused by heavy rain that destroy everything. Earthquakes are caused by movement of tectonic plates under the surface, with 4/5 occurring in the Pacific Rim. Avalanches are like mudslides but made of snow and ice occurring after fresh snowfalls in mountains at speeds up to 128 kph.
Disaster management
There are two main types of disasters - natural disasters which are caused by phenomena like earthquakes, floods, or droughts, and man-made disasters caused by human actions. Some regions are more prone to certain natural disasters based on their geography and climate. India is highly disaster prone, with many parts of the country vulnerable to earthquakes, floods, cyclones, and droughts. When disasters strike, they can have devastating effects like loss of life, property damage, infrastructure damage, and economic losses. Proper disaster management aims to mitigate these impacts by improving preparedness, coordination of relief efforts, early warning systems, public awareness, and stockpiling of emergency resources.
Hurricanes
Hurricanes are severe tropical storms that form over warm ocean waters and contain heavy rain, strong winds, and storm surges. They rotate counter-clockwise around an eye and require winds of at least 74 mph to form. Hurricane Katrina was the costliest natural disaster in U.S. history, causing massive damage when it made landfall in New Orleans in 2005 and flooding the city after levees failed, leaving over 100,000 people still in the city. It resulted in thousands of deaths and widespread destruction across Louisiana, Mississippi, and Alabama.
Hurricanes 1231546204899344-1
Hurricanes are tropical cyclones that form over warm ocean waters and have sustained winds of at least 74 mph. They have an eye at the center surrounded by the eye wall with the strongest winds and rainbands spiraling outward. The Coriolis effect causes hurricanes in the Northern Hemisphere to turn counterclockwise. Hurricanes are categorized on the Saffir-Simpson scale from 1 to 5 based on wind speed, with category 5 storms having winds over 155 mph and posing catastrophic damage. Climate change is causing hurricanes to increase in intensity.

Cable stay bridge construction
1) Cable-stayed bridges have the deck supported by cables running directly from the deck to towers. They are economical for long spans over 100 meters, especially where access is restricted.
2) Construction involves building cofferdams and installing piles and rebar cages for foundations before constructing the tower and deck segments, which are placed using temporary cables.
3) Permanent cables made of strands coated in plastic and resin are installed by forcing them through pipes to saddles in the tower and stressed using hydraulic jacks on both sides.
Cable stay bridges, summary of a lecture delivered at Uni of Surrey, UK
Cable stay bridges, summary of a lecture delivered as part of MSc course at University of Surrey UK. Outlines key issues for sizing major bridges. The work draws on Manual of bridge Enginnering, the authors book Steel Concrete composite bridges - which has a chapter on cable stay bridges, and recent research on cable stay and extradosed bridges.
Basics of bridge construction
This document outlines the steps taken to build a spaghetti bridge that meets specific requirements. It describes researching bridge design, creating a prototype, testing it, redesigning based on weaknesses found, and building a final bridge that supports 15 pounds. The process involved learning about bridge engineering, designing a Warren truss bridge made of spaghetti, constructing and testing a prototype, redesigning to address issues, and finally building a bridge that spanned 20-30 inches and supported 15 pounds.
Bridges
The document discusses various topics related to bridges including their purpose, importance, components, classifications, loadings, aesthetics, materials used such as steel and reinforced concrete, types of bridges like suspension bridges, causes of bridge failures, maintenance, and some landmark bridges in India. Bridges are structures built to provide passage over physical obstacles without closing the gap below and have been developing in sophistication since early human civilization. They are important for connecting difficult terrains, aiding trade and transportation, and reducing travel time.
Suspension bridge
Suspension bridges have several key components: cables that suspend the roadway from towers, towers that stabilize the cables, and anchorages that provide structure and keep the cables tight. A typical construction process involves building tower foundations, erecting the towers, installing saddles and cables between the towers, adding vertical suspender cables to hang the roadway, and constructing the deck between the towers. The main forces in a suspension bridge are tension in the cables and compression in the towers. Some of the world's largest suspension bridges include the Akashi Kaikyō Bridge in Japan and the Sidu River Bridge in China.

Natural disaster
There are differences between natural disasters and man-made social problems. Natural disasters are caused by natural forces like earthquakes, hurricanes, floods, etc. while man-made problems are caused by human activities like accidents, wars, terrorism. Natural disasters tend to disproportionately impact poorer countries and communities that have less ability to prepare for and respond to disasters due to lack of resources and infrastructure. While disasters may initially seem purely natural, human activities can exacerbate their impacts through issues like environmental degradation, lack of disaster planning, and unequal social vulnerabilities. It is important to consider both the natural and human factors that contribute to disasters.
Natural disaster
This document discusses the differences between natural problems and social problems. It provides examples of natural disasters like earthquakes, tsunamis, hurricanes, floods, volcanic eruptions, and avalanches. It explains that while the causes of these disasters may be natural phenomena, the impact and damage is often exacerbated by human factors like poverty, lack of infrastructure, and environmental degradation. For social problems, it notes that a social problem is defined as an undesirable condition that threatens people's quality of life and values. Social problems result from issues related to a society's perceptions and norms. The document contrasts natural disasters with social issues.

Hurricane presentation cooper kai connor
Hurricanes are large rotating storm systems that form over warm ocean waters. They develop from tropical storms and require ocean temperatures of at least 79°F. As the storms draw energy from the warm ocean, moisture evaporates and condenses, causing the winds to circle around the storm's low pressure center. The most destructive hurricanes have sustained winds over 74 mph. Hurricane Katrina in 2005 was one of the deadliest, causing over $100 billion in damage and thousands of deaths along the Gulf Coast. To mitigate hurricane damage, buildings can be constructed to withstand high winds and flooding through sturdy foundations and supportive structures.

14. cyclone nargis
Cyclone Nargis caused severe damage in Myanmar in 2008. It formed over warm waters in the Bay of Bengal and traveled west, making landfall in Myanmar. The storm caused catastrophic damage due to strong winds and heavy rainfall. Over 138,000 people were killed or left missing. The damage was exacerbated by the lack of early warning systems and destruction of coastal mangrove forests that normally help protect against storm surges.
5 cs, lesson 11
Hurricane Sandy formed in the Caribbean in October 2012 and made landfall in New Jersey as a Category 1 hurricane with winds up to 70 knots. It caused catastrophic flooding and a massive storm surge along the East Coast. Over 285 people died and $75 billion in damages occurred across 24 affected states. Key impacts included widespread power outages, transportation shutdowns, and destruction of homes and coastal infrastructure.
All about hurricanes!
Hurricanes are massive, spiraling tropical storms that form over warm ocean waters and have wind speeds over 160 mph. They form when warm, moist air rises from the ocean surface, causing surrounding air to spin inward to replace it. As the warm air rises and cools, water vapor condenses to form clouds that continue to grow while fed by evaporating water. Hurricanes can cause extensive damage from high winds and flooding along coastlines and hundreds of miles inland from heavy rains. They typically occur between June and November in the Atlantic and eastern Pacific basins, and year-round in the western Pacific, with peak activity in late summer and early fall. The greatest threats from hurricanes are drowning and flying debris due to coastal
Part 4. 2014 notable disasters. floods
Floods, which can be either slow onset or rapid onset events (i.e., flash floods), occur when a locale cannot process the amount of water that it is receiving in a normal manner. Communities throughout the world know why it is urgent for their stakeholders to continue working on becoming FLOOD and especially FLOOD-INDUCED LANDSLIDE DISASTER RESILIENT. Each community knows that it is only a matter of time until the inevitable flood event occurs that can expose its physical and social vulnerabilities. THE REASONS FOR A FLOOD DISASTER TO OCCUR: The community is UN-PREPARED for the flood hazards (INUNDATION, LANDSLIDES, etc.,) that are likely to happen. The community has NO DISASTER PLANNING SCENARIO or LAND USE PLANS or ORDINANCES in place as a strategic framework for identification and coordinated local, national, regional, and international countermeasures. The community has NO EARLY WARNING SYSTEM or COMMINITY EVACUATION PLANS in place as a strategic framework for identi-fication and coordinated local, national, regional, and international countermeasures. The community LACKS THE CAPACITY TO RESPOND to the full spectrum of expected and unexpected emergency situations in a timely and cost-effective manner. The community is INEFFECIVE during recovery and reconstruction because it HAS NOT LEARNED IMPORTANT LESSONS from either the current experience or the cumulative prior experiences.

Cyclone 1
This document provides an overview of cyclones, including:
1) How cyclones form due to rising warm moist air over oceans creating low pressure areas filled by surrounding high pressure air.
2) The main types of cyclones are tropical, polar, mesocyclones, and extratropical. Cyclones are named by regional meteorological centers.
3) India experiences many deadly cyclones such as the 1970 Bhola cyclone that killed 300,000-500,000 people in Bangladesh and India. Recent major cyclones include Fani, Amphan, Tauktae, and Yaas.
Hurricanes
Hurricanes form over warm ocean waters and require winds of at least 74 mph. They can last 1-12 days and cause significant damage through heavy rain, strong winds, and storm surges. Hurricane Katrina struck the Gulf Coast in August 2005 as a category 3 storm, causing over 1,800 deaths and widespread destruction across New Orleans through flooding and property damage.
Hurricanes
1) Hurricanes form over warm ocean waters and require specific conditions including high heat, humidity, and low wind shear.
2) Hurricanes develop through several stages from formative to mature as the eye forms and winds intensify.
3) Hurricanes can cause both short term damage through winds and flooding as well as long term destruction through landscape alterations.
Hurricane Hugo 1989
A sudden disaster. Hurricane Hugo was not expected to have much strength left by the time it reached Charlotte, NC. Instead, it was a Category 4 storm when it made landfall in SC and still a cat. 1 when it hit Charlotte. Coastal storm surges were 15 to 20 feet above normal. After Hurricane Hugo caused at least 86 deaths and upwards of $10 billion in damages 30 years ago, the World Meteorological Organization retired the name. There would never be another Hurricane Hugo.
Hurricane sandy

Wak disasters
Earthquakes occur along fault lines when tectonic plates collide or scrape against each other. The San Andreas Fault in California is responsible for some of the most destructive quakes in U.S. history due to the North American and Pacific plates scraping past each other there. Major quakes can cause tsunamis, massive ocean waves caused by underwater seismic activity that can devastate coastal areas.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Climate Impact of Software Testing at Nordic Testing Days
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.
Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Epistemic Interaction - tuning interfaces to provide information for AI support
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
