Earthquakes

The way earthquakes are made is when two tectonic plates move together, then the oceanic crust to form a subduction zone. This creates a ocean trench whcih forms as the ocean form is pulled downwards. When this buckles it forms mountainn ranges. When the plates move against eachother the pressure builds up and when released causes earthquakes.

 Social impactsEconomic impactsEnvironmental impacts Short-term (immediate) impacts People may be killed or injured. Homes may be destroyed. Transport and communication links may be disrupted. Water pipes may burst and water supplies may be contaminated. Shops and business may be destroyed. Looting may take place. The damage to transport and communication links can make trade difficult. The built landscape may be destroyed. Fires can spread due to gas pipe explosions. Fires can damage areas of woodland. Landslides may occur. Tsunamis may cause flooding in coastal areas. Long-term impacts Disease may spread. People may have to be re-housed, sometimes in refugee camps. The cost of rebuilding a settlement is high. Investment in the area may be focused only on repairing the damage caused by the earthquake. Income could be lost. Important natural and human landmarks may be lost.

Destructive- Where plates move towards eachother and they cause volacanoes and earthquakes.

Constructive- Wheres plates move away from eachother which cause earthquakes and volcanoes.

conservative- Where plates slide past eachother which vause strong earthquakes.
