Point within the Earth where the rock under stress breaks
Epicenter
Point directly above the focus on the surface
People are buried under piles of rubble of collapsed buildings
You cannot reach remote villages as the climate and roads are blocked by landslides
People need food, shelter, medicine and power. People are sleeping outdoors due to fear of aftershocks
Earthquakes do not happen often
In the Case of Nepal's earthquake in 2015, they were severely damaged as it was a major earthquake but also they did not have resources to prepare for the earthquake. This can be said for many countries
If proper precautions are taken, the risk is reduced. These include improvements in forecasting, safer buildings and emergency drills have greatly reduced the number of deaths
In MEDCs, a building falling down is much less likely to happen as there are strict buildingS codes to follow. However in Ledcs, the Gvt. and People do not have money to do the same
Drop! Cover! Hold on!
1. Drop onto your knees and hands to stop yourself from getting knocked over
2. Cover your head and neck with one arm and hand, and if you can crawl under a desk or crawl to an interior wall away from the windows
3. Hold on till the shaking stops!
Earthquake resistant building features
Cross-bracing reinforces walls using two steel beams
Base isolator
Shock Absorbers, absorb tremors of earthquakes
Shear Wall: Concrete walls with steel bars in them
Shear Core: resists lateral damages from heavy winds and earthquakes
Moat
Volcano
Openings or cracks in the lithosphere, where magma from inside the Earth can escape onto the surface
Forms of magma eruption
As liquid lava flows from the vent or crack
As volcanic bombs - lumps of molten rock that solidify as they explode out of the vent and fall to earth
As hot ash and dust are thrown into the atmosphere and eventually fall back to earth, sometimes hundreds of kilometers from the volcano
Steam and Gas, which may be poisonous
Crater
A roughly circular opening at the summit (top) of the volcano
Magma
Molten rocks beneath the earth's Surface
Volcanic bombs
Balls of molten rock that solidify as they fall
Falling ash
Small pieces of shattered rock and thrown from the volcano
Secondary cones
If the main vent is blocked the magma is forced to the surface by another route
Types of volcanoes
Active
Dormant
Extinct
People choose to live near volcanoes because they consider the advantages outweigh the disadvantages. Most volcanoes are safe for long periods of time between eruptions and those that erupt frequently are usually considered, by the people who live nearby, as being predictable
Advantages of Living Near Volcanoes
Fertile soil that is good for agriculture
The presence of minerals
Geothermal energy
Tourism: Volcanoes attract millions of visitors every year
Volcanologists
Monitor volcanoes all over the world, taking readings, to determine change so they can predict whether a volcano is likely to erupt
Planning for volcanic eruptions
Drawing up evacuation plans
Using hazard maps to prevent building in high risk areas where lava might flow
Setting up warning systems
Responding quickly to advice from volcanologists
Educating people on what to do if a nearby volcano erupts. Tokyo, in Japan is at risk of a range of hazards including volcanoes. The city authority has produced a hazard guide
Tiltmeter
Used to detect a change in the slope of the land. Bulging on the surface can indicate significant pressure in the rock and ground below
Seismograph
Detects vibrations in the Earth's crust. The foreshocks occur prior to an earthquake
How to Protect Yourself
1. Confirm the dangerous areas on the disaster prevention map
2. Prepare food and items for a disaster
3. Confirm a designated evacuation center beforehand

As of plate movements (Arabia, Eurasia, Africa), there are many volcanoes, and earthquakes that have taken place or have been made by these movements
The Arabian plate moves 3cm north every year, it has collided with the Eurasian plate; creating fold mountains

Climatic zones of the Middle East
Mediterranean climate towards the north
Deserts towards the south
Arabian Peninsula climate
Mostly desert. Rain falls mostly between May and September, having 0 rain in the winters. The sun bakes people of this region. The nighttime temperatures are low
Northern Middle East climate
Hot dry summer when weather resembles a desert, and warm wet climates. This dry climate, rises problems of water scarcity
Water scarcity causes droughts which is a lack of water for plant growth and animals. Famine ( a lack of crops for food) and a lack of water
