MEDC's are more likely to have the resources and technology for monitoring, predicton and response. Accessibility for rescue teams, Influences whether people are in their homes, at work or travelling.

Economically developed countries (Less + more)
A severe earthquake at rush hour in a densely populated urban area could hae devestating effects. Influences survival rates and the rate at which disease can spread.

Economically developed countries (Less + more)
The more densely populated an area is, the more likely there are to be deaths and casulaties.The effects of an earthquake are more severe at its centre.
3 of 9
Constructive Plate Boundary
Convection currents in themantlecause two plates to move apart. As they move apart, magma from the middle rises to the surface and cools forming new crust. E.g. the mid-Atlantic ridge (Iceland)
4 of 9
Destructive Plate Boundary
Convection currents in the mantle cause two plates to move towards each other. The denser OC is forced down under the CC into the mantle. The heat of the mantle and friction causes the plate to melt. It then rises up through the CC forming a volcano.
5 of 9
Collision Plate Boundary
Convection currents in the mantle cause two continental crusts to move towards each other. As they meet they are of the same material so they crumple upwards to form fold mountains. E.g. the Himalayas.
6 of 9
Conservative Plate Boundary
Convection currents in the mantle cause two plates to slide past each other. As they do this, they stick and then slip, causing earthquakes. E.g. San Andreas Fault, LA, USA

Lithosphere
The crust and the solid top layer of the mantle known as 'lithosphere'
