Natural hazards pose threats to critical infrastructure in Algeria. Earthquakes and floods are the most likely to impact infrastructure sectors like energy, communications, transportation, and government services. Over 60 oil and gas installations are located in seismic zones along the coast. More than 21,000 km of pipelines cross high-risk northern areas. Earthquakes have the highest potential to cause casualties and damage the economy. Climate change is increasing the frequency and severity of floods as well. Most of Algeria's population and wealth are concentrated in highly vulnerable cities.

On November 19, 1984, a series of explosions occurred at a liquefied petroleum gas (LPG) storage and distribution facility in San Juanico, Mexico City, operated by Pemex, Mexico's state-owned petroleum company. An 8-inch feed pipe ruptured, releasing a gas cloud that ignited and caused the first explosion. This was followed by 18 additional explosions over the next 1.5 hours as fires engulfed the facility's LPG storage tanks. The explosions and fires killed 500-600 people, injured 5000-7000, and left 10,000-60,000 homeless. Lessons learned included the need for proper plant layout and maintenance, adequate safety systems, and housing located further

The regulations provide rights for safety representatives to represent employees and investigate potential hazards.

Roadmap for airport service delivery measurement - Alaistair Deacon

Amor Group

This document outlines a roadmap for improving the passenger experience at airports through better service delivery measurement. It proposes developing key performance indicators and collecting baseline data on current processes using technology like mobile tracking and video analytics. A "model for excellence" would integrate this data to provide actionable information for collaborative decision-making between stakeholders. The goal is to engage passengers, operations staff, and airlines to define what constitutes excellent service, measure it, then continuously improve processes and maintain excellent service standards over time.

tragedy in vargas,Venezuelan

Nachiketa Mithaiwala

The Vargas Tragedy of 1999 in Venezuela was caused by unusually heavy rains in December that triggered thousands of landslides and debris flows along mountainsides north of Caracas. These flows swept down into populated coastal areas, killing an estimated 10,000 to 50,000 people and leaving over 150,000 homeless. Infrastructure like roads, bridges, and ports were destroyed, crippling transportation and the economy. In the aftermath, authorities established new organizations to oversee reconstruction, installed sediment control dams and early warning systems, and rebuilt damaged infrastructure over the following decade, though thousands remained homeless and the full recovery was still ongoing years later.

Assessment of the Frequency and Return Period for Extreme rainfall Causing Fl...

International journal of scientific and technical research in engineering (IJSTRE)

Different types of geological hazards such as earthquake, volcanic eruption, flooding, rock falls, sand problems, and subsidence will endanger people and their properties in Saudi Arabia. Identification, evaluation and mitigation of geo-hazards are a vital task that should be considered in the city planning, so, estimating the frequency, magnitude and recurrence are considered the ways that help to mitigate the effects of the natural hazard to people and assets. In arid regions, flash floods often occur. Rainfalls which cause flash floods are a deadly and costly event that can be exacerbated in arid environments.Consequence of excessive rainfall occasionally causing major loss of property and life, floods are large events of relatively short duration. In this study,the history of rainfall data are collected and analyzed to get an idea about the floodbehavior in Makkahduring the previous years, the Weibull distribution is used for this purpose.

IRJET-Investigation of Landslides and its Effects on Kothagiri

IRJET Journal

This document summarizes an investigation of landslides and their effects on Kothagiri in India. The investigation utilized remote sensing techniques like IKONOS satellite imagery and GIS mapping to identify and analyze landslides in the area. Field investigations were also conducted to study the geological features of landslides and recommend countermeasures. Different types of landslides were identified and their causes like geological, morphological, and human factors were examined. The methodology involved preparing detailed maps from remote sensing data, conducting field surveys, hazard mapping of landslides, and developing guidelines for roadside slope inspection and maintenance. The conclusions highlighted the role of remote sensing and GIS in landslide mapping and how a combination of these techniques can help landslide risk assessment.

Exploring Natural Hazards

Philwood

This document discusses natural hazards and Hurricane Dorian. It defines natural hazards as natural phenomena that can negatively impact humans or the environment. These are classified as geophysical, like earthquakes, or biological, like disease. Hurricane Dorian caused widespread damage in the Bahamas in September 2019, with over 50 deaths reported. Infrastructure on the Abaco Islands and Grand Bahama was destroyed, leaving thousands without power, water or telecommunications. Climate change may increase the intensity of tropical storms by raising sea surface temperatures and sea levels, exacerbating damage during storms. Reducing vulnerability involves preserving coastal ecosystems, infrastructure improvements, and disaster preparedness.

Impact analysis for flooding AREA, In SAUDI ARABIA

International journal of scientific and technical research in engineering (IJSTRE)

In all words the natural hazard can affect the life and the assets and make real bad impact that will put the affected area and human in bad situation .The aim of this study was to explore the analyze the impact of the floods in different cities in Saudi Arabia. Western Saudi Arabia is one of the arid areas which occasionally subjected to flash flooding effects due to excessive rainfall. The most important and holiest areas in this region are Makkah and El-Madeinah which are of great importance not only to Saudi people, but also for whole Muslims all over the world are also affected by such flooding disasters. This piece also will present the cases of Jeddah 2009 floods and Riyadh 2010 floods and other events as the most recent disasters in the region. These events were chosen since they are very recent, and have awakened policy makers to shift their emergency preparedness efforts to a more active approach. The results of this research present and idea about the looses in life and assets in case of the flood happen and give the people the full awareness to try avoiding the danger of the foods which consider one of the very dangerous natural hazard . Data were collected for this qualitative study between 1964 and 2015.

Volcanic ash and aviation emergencies

Prof. David E. Alexander (UCL)

The 2010 eruption of the Eyjafjallajökull volcano in Iceland grounded flights across Europe for several weeks, stranding millions of travelers. While volcanic ash poses a serious hazard to aircraft engines, the response to this eruption revealed issues with Europe's preparedness and coordination for such an event. Specifically, the safe ash concentration levels that triggered flight bans were established without scientific basis. Additionally, individual country responses were not well integrated across Europe. Future eruptions, especially of larger volcanoes, could cause significantly longer disruptions, highlighting the need for improved volcanic risk assessment and cross-border emergency planning in Europe.

Mechanisation Vs Accidents in Mining

VR M

The document discusses the benefits of mechanizing mining operations to improve safety standards and phase out manual loading. It provides statistics showing a reduction in accidents, especially those due to roof and side falls, after mechanization was introduced at mines operated by SCCL in India. Mechanization led to a 50% reduction in fatalities and allowed experienced workers to be redeployed to safer roles. However, additional safety precautions are needed to address new risks from increased electricity, moving machinery, and equipment maintenance.
