The document discusses various coastal landforms created by erosion and deposition processes. It explains that waves break as they approach land due to increased friction. Swash carries water up the beach while backwash carries it down. Larger waves in the southwest are due to greater wind fetch. Cliffs and wave-cut platforms form through erosion processes like abrasion. Caves, arches, stacks and stumps also form through erosion. Beaches form in sheltered areas due to stronger swash depositing sediment. Spits and bars form through longshore drift depositing sediment. Tombolos connect landmasses.
AS GEOGRAPHY - ROCKS AND WEATHERING: SLOPE PROCESSES AND DEVELOPMENTGeorge Dumitrache
Mass movements are large-scale movements of earth that are not caused by rivers, glaciers, or waves. They include slow movements like soil creep and fast movements like avalanches. Mass movements are caused by a reduction in the internal strength of a slope or an increase in downward forces. Common types of mass movements are falls, slides, slumps, flows, and avalanches.
The document discusses coastal environments and processes. It begins by defining a coast and describing the different zones and landforms that make up coasts, such as beaches, headlands, and cliffs. It then explains how coasts are dynamic environments that change over time due to various natural processes and forces, including waves, tides, currents, geology, and ecosystems. Specific coastal erosional processes like corrasion, attrition, solution, and hydraulic action are also outlined.
AS GEOGRAPHY - ROCKS AND WEATHERING: WEATHERING AND ROCKSGeorge Dumitrache
Physical weathering breaks rocks into smaller pieces through processes like heating and cooling or wetting and drying. Chemical weathering alters the mineral composition of rocks through reactions with water and acids. Limestone landscapes feature karst topography with features like caves, sinkholes, and limestone pavements formed by the dissolution of calcium carbonate in the rocks. Granite weathers through freeze-thaw action and hydrolysis, forming tors and soil. The rate and type of weathering depends on climate, rock type, relief, vegetation and other factors.
The document provides information about different types of mass movement or slope failure. It begins by defining different types of slopes including crests, free faces, talus slopes, and pediments. It then discusses various types of mass movement processes including creep, slump, debris flow, earth flow, and rockslides. The role of water in triggering mass movements is described. The document also addresses human impacts including urbanization and deforestation that can cause landslides. It concludes with ways to prevent landslides such as drainage control, slope grading, and avoiding hazardous areas.
The document discusses the global distribution of tectonic hazards such as earthquakes, volcanoes, and tsunamis. It explains that most earthquakes occur along well-defined plate boundaries, including subduction zones where one plate slides under another, and collision boundaries. Narrow earthquake belts are associated with constructive margins where new crust is forming and plates are moving apart. Broadly, the document provides an overview of the types and causes of tectonic hazards around the world.
This document discusses mass wasting, which refers to the downslope movement of earth materials under the influence of gravity.

Understanding the human element is critical because population growth is increasing the number of people living in hazard-prone areas. While the geological processes cannot be stopped, efforts can be made to mitigate hazards through scientific study, education, engineering practices, and emergency management. Specific natural hazards like earthquakes, tsunamis, and tropical cyclones are then examined in more detail including how they form and the damage they can cause.
Earthquakes in view of Paramedical Educationkotavamshi28
The document discusses earthquakes, including their causes, types of faults, measuring devices, seismic zones in India, notable earthquakes in India, hazards and impacts, risk mitigation, and the role of emergency medical services. It provides an overview of plate tectonics and the movement of tectonic plates, describes different types of faults such as reverse, normal, and strike-slip faults. It also outlines seismic zones in India based on past earthquakes and risk, as well as some major earthquakes that have caused significant damage and loss of life in India.
Plate tectonics involves the slow movement of tectonic plates across the Earth's surface, driven by convection currents in the mantle. Alfred Wegener first proposed continental drift in 1915, but it was not until the 1960s that seafloor spreading provided evidence that plates move independently. There are 7 major and many minor tectonic plates that either move apart at mid-ocean ridges or come together, causing earthquakes and volcanic activity at plate boundaries. Hazards are greatest where plates meet and include earthquakes, tsunamis, and eruptions that depend on the plate boundary setting and composition of the colliding plates.
The document discusses different types of natural and man-made disasters. It categorizes natural disasters as meteorological, topographical/geological, and environmental. Man-made disasters are categorized as technological, industrial, and warfare. Specific natural disasters discussed include floods, cyclones, earthquakes, tsunamis, volcanoes, landslides, and more. Man-made disasters include accidents, pollution, industrial accidents, and wars. The document also provides details on the causes and impacts of various disasters like earthquakes, floods, oil spills, and epidemics. Classification schemes for different types of disasters are presented.
An earthquake is caused by a sudden release of energy in the earth's crust that creates seismic waves. The intensity and magnitude of an earthquake is measured on the Richter scale. Seismometers measure earthquake motions, and seismic waves include body waves that travel through the earth and surface waves that travel along the surface. Most major earthquakes occur at plate boundaries and are caused by the buildup and sudden release of pressure between tectonic plates. Earthquake effects include loss of life and property damage. Early warning systems aim to detect earthquakes quickly through primary seismic waves to warn of impending stronger secondary waves.
The Earth's layers are constantly changing due to internal heat and gravitational/solar energy. Convection currents in the mantle and lithospheric plates slowly moving due to mantle convection cause geological processes at plate boundaries. Plates can be converging, diverging, or moving conservatively parallel to each other, resulting in ocean ridges, trenches, and faults respectively. Plate dynamics produce volcanic eruptions, earthquakes, and shape the Earth's surface relief through mountain building and changing ocean basins over millions of years.
1) Earthquakes occur along fault lines in the earth's crust due to the buildup and release of stress as tectonic plates shift.
2) There are three main types of faults that can form from different types of stress: normal faults from tension, reverse faults from compression, and strike-slip faults from shear stress.
3) When stress is released along a fault, seismic waves are generated including faster P and S body waves and slower surface Love and Rayleigh waves.

"Scaling RAG Applications to serve millions of users", Kevin GoedeckeFwdays
How we managed to grow and scale a RAG application from zero to thousands of users in 7 months. Lessons from technical challenges around managing high load for LLMs, RAGs and Vector databases.
From Natural Language to Structured Solr Queries using LLMsSease
This talk draws on experimentation to enable AI applications with Solr. One important use case is to use AI for better accessibility and discoverability of the data: while User eXperience techniques, lexical search improvements, and data harmonization can take organizations to a good level of accessibility, a structural (or “cognitive” gap) remains between the data user needs and the data producer constraints.
That is where AI – and most importantly, Natural Language Processing and Large Language Model techniques – could make a difference. This natural language, conversational engine could facilitate access and usage of the data leveraging the semantics of any data source.
The objective of the presentation is to propose a technical approach and a way forward to achieve this goal.
The key concept is to enable users to express their search queries in natural language, which the LLM then enriches, interprets, and translates into structured queries based on the Solr index’s metadata.
This approach leverages the LLM’s ability to understand the nuances of natural language and the structure of documents within Apache Solr.
The LLM acts as an intermediary agent, offering a transparent experience to users automatically and potentially uncovering relevant documents that conventional search methods might overlook. The presentation will include the results of this experimental work, lessons learned, best practices, and the scope of future work that should improve the approach and make it production-ready.

Essentials of Automations: Exploring Attributes & Automation ParametersSafe Software
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.

• The impact of tectonic
processes on the landscape
• The impact of tectonic hazards
on people
• The ways in which people
respond to, and try to manage,
natural hazards.

4. 1. Tectonic activity and causes
• Tectonic activity can produce a
very large range of hazard events
• Not all of these events are
‘disasters’
• A natural hazard event becomes
a disaster when the event causes
a significant impact on a
vulnerable population.
• These impacts could be human
(death, injury) and / or economic
(property losses, loss of income).
• Definitions vary, but ‘significant’
losses usually means 10+ deaths /
100+ affected / $1 million losses.
The Dregg disaster model
5. Event profiles
• Not all tectonic hazards are the same
• Event profiles are a common way of comparing
different hazards
• In this example the 2004 Asian Tsunami and ongoing
eruption of Kilauea on Hawaii are compared
• Hazard profiles can be drawn for any event.
6. Earth’s heat engine
• Tectonic processes are
driven by radioactive
decay in the core
• This decay generates
heat inside the earth,
which drives vast
convection currents
• This convection is
largely responsible for
plate movement
7. Tectonic settings and plates
• Most tectonic hazards are concentrated at plate margins
(boundaries), although ‘hotspots’ are a notable exception.
• Different types of boundary generate very different tectonic
hazards.
8. The range of volcanic hazards
• Dangerous volcanic
hazards are found
along subduction
zones at destructive
plate margins
• The most dangerous
volcanoes are
themselves multiple
hazard areas.
• Volcanoes at
constructive plate
margins (Iceland) and
oceanic
hotspots(Hawaii) are
much less hazardous
and destructive.
9. Magma generation
Magma
type
Generation Tectonic setting Hazards
Basaltic
Low silica, low gas, low
viscosity.
Dry partial melting of
upper mantle
Oceanic Hot spot (Hawaii)
Constructive (Iceland)
Lava flow
Andesitic
Intermediate
Wet partial melting of
subducting plates
Destructive plate margin
(Andes)
Island arc margin
(Montserrat)
Lava flow, ash and tephra,
pyroclastic flow, lahar, gas
emission
Rhyolitic
High silica, high gas, high
viscosity.
In situ melting of
lower continental
crust
(very rare eruptions)
Continental Hot spot
(Yellowstone)
Continent collision zone
(Himalayas)
Cataclysmic explosion,
pyroclastic flow
• Magma, molten rock in the earth’s crust, has an important relationship
with volcanic explosivity and hazard level
• Andesitic magmas, formed by wet partial melting at subduction zones
produce highly explosive and destructive composite volcanoes
10. Measuring volcanic explosivity:
• The Volcanic
Explosivity Index (VEI)
is used to measure
volcanic power.
• VEI measures: Volume
of ejecta Height of the
eruption column
Duration of the
eruption.
• Modern humans have
never experienced a
VEI 7 or 8
11. Earthquakes
• Earthquakes are a very
common, sudden release of
energy that generate seismic
waves
• Most occur along faults (cracks
in the earth’s crust) which
become ‘locked’
• Opposing tectonic forces push
against the locked fault,
building up strain, which
eventually gives way releasing
stored energy
• This energy spreads out rapidly
from the earthquake origin (the
focus) reaching the surface at
the epicentre, and then
spreading horizontally.
12. Tsunami
• Tsunami are relatively rare events.
• They are generated by submarine earthquakes, volcanic collapse, and
coastal landslides, which suddenly displace huge volumes of water
• The 1993 Okushiri tsunami (Japan), 2004 Asian Tsunami and 2009 Samoa
events are all useful as case studies.
• Tsunami waves are radically different from normal wind generated ocean
waves.
• When a tsunami hits a coastline, the effect is more like a devastating
coastal flood than a single breaking waves
13. 2. Tectonic hazards physical impacts
• Tectonic processes play a key
role in forming the landscape
around us
• Volcanic activity and the
movement of tectonic plates
create mountains, plateaux
and other landscape features
• These landscapes are then
modified by
geomorphological processes
(weathering, rivers, ice, wind
and slope processes)
14. Magma type and volcano morphology
• Volcanoes are extrusive igneous landforms. The form of volcanoes
is related to magma types, and therefore to different tectonic
settings:
• Basaltic – huge, low relief shield volcanoes plus small scoria cones
and fissure vents.
• Andesitic – steep sided strato-volcanoes; layers of lava, ash and
tephra.
• Rhyolitic – central craters with lava plugs / domes, due to high
viscosity of the lava. Calderas and collapse calderas.
15. Extrusive igneous activity
• Large scale outpourings of basaltic magma, called flood basalts,
have occurred at various times in the past.
• These produce distinctive lava plateaux and stepped or ‘trap’
topography
16. Intrusive igneous activity
• The injection (intrusion) of magma below the surface can
produce characteristic landforms
• Igneous rock normally resists weathering and erosion in
comparison to surrounding rocks, which produces positive relief
features.
• Large intrusions such as batholiths produce upland areas,
whereas minor intrusions produce smaller landscape features
17. Earthquakes and
faults
• Tectonic movements and movements along faults (which
generate earthquakes) also produce distinctive landforms and
relief:

18. 3. Tectonic hazards human impacts
• A surprising number of
people live in areas of
active tectonic processes
• Major tectonic hazards can
strike with devastating
force
• The 2005 Kashmir
Earthquakes killed around
85000, the 2008 Sichuan
‘quake over 65,000 and
200,000+ died in the 2004
Asian Tsunami
• It is important to consider
why people live, in such
large numbers, in areas of
great risk
19. Impacts
• Every hazard event is different, and therefore the specific
impacts of disaster vary
• When researching case studies, it is important to be able to
identify specific impacts and be able to explain these
• Some impacts are tangible and can be given a financial value.
Others are intangible, such as the destruction of a temple or
artwork.
• Many losses are direct and immediate such as property
damage, but others are indirect – these come later and are
harder to quantify, such as stress and psychological damage.
• Impacts are often considered as human (death, injury,
illness), economic (property loss, loss of income, cost of
relief effort) and physical (changes to landscape and
topography).
20. • Examine the two earthquakes below and consider how factors such as
economic development, building types, the geography of the area
affected and the relief effort may have affected the impacts

21. Developed versus developing world
• It is often said that
disaster impacts in
the developed world
are largely economic,
whereas in the
developing world they
are human (death).
• You should carefully
consider if this
generalisation is true.
(see the table, right)
• The 1995 Kobe
earthquake in Japan
and 1991 eruption of
Mt Pinatubo in the
Philippines are useful
examples to consider

22. Impacts over time
• A simplified version of Park’s hazard response model is shown
below
• Different hazard events have different impacts, shown by the
speed of the drop in quality of life, the duration of the decline,
and the speed and nature of recovery.
• The differences in the 3 lines might be related to type of
hazard, degree of preparedness, speed of the relief effort and
the nature of recovery and rebuilding.
23. 4. Response to tectonic hazards
• People cope with natural
hazards in very different ways
• The chosen ways are often
related to wealth and access
to technology
• Humans do have a capacity to
ignore or seriously
underestimate risk, even when
it seems obvious to others
• Often it may seem obvious that
people should move out of
harms way, but in reality this
may be impossible.
24. Hazard modification
• Several different approaches can be taken to reduce the impacts of
tectonic hazards:
Modify the
event
(hazard
mitigation)
Modify human
vulnerability
Modify the
loss
Tsunami Coastal defences
and engineering
•Warming and prediction systems
•Coastal zone management and
landuse planning
•Provision of emergency kits
Loss modification
involves immediate
rescue efforts,
followed by relief
efforts which focus
on food, shelter,
water and
sanitation.
Insurance can help
recovery.
Long term
reconstruction is
needed.
Earthquakes Not possible •Ground shaking and liquefaction
risk mapping
•Aseismic buildings
•Earthquake education and drills
•Prediction not possible
Volcanoes Lava diversion •Monitoring, prediction warning
and evacuation systems
•Hazard mapping e.g. lahar risk
•Education
•Shelters
25. The hazard management cycle
• Successful hazard
management involves a cycle
(see diagram) which focuses
on the 3 types of modification
from the previous slide.
• A focus on modifying loss only,
will not improve survival
chances when the next hazard
strikes
• Long before a natural hazard
event, there needs to be a
focus on mitigation and
prevention (if possible) as well
as human preparedness.
