Outline the demographic and social impacts of one or more tectonic events

8 August 2016

I will be outlining the demographic and social impacts of Mount St Helens and the Bam earthquake. Mount st Helens caused fifty seven deaths compared to the Bam earthquake which caused over 25,000 deaths and 30,000 injuries. The earthquake in Bam in 2003 was the worst earthquake in Iranian hisrory and was situated in an overpopulated poor city in Iran therefore more people lost their lives.

The eruption of Mount St Helens in 1980 Washington was situated in the Cascade mountain range so the area was very sparse therefore less lives were lost and also people were more prepared for this event because it is in a MEDC unlike the area in which the earthquake in Bam struck. The Mount St Helens eruption destroyed 200 homes because of its pyroclastic flows and the ash fall caused problems with transport links, sewage disposal and water treatment.

Outline the demographic and social impacts of one or more tectonic events Essay Example

In Iran, 75% of homes were completely destroyed leading to over 100,000 people becoming homeless because of the poorly made, multi storey buildings and homes which immediately collapsed and nearly 90% of buildings and infrustructuer in the area was destroyed or damaged. Over 2,000 years of historic buildings and memorabilia was lost and damaged when the earthquake in Iran struck. This caused many upset residents as their heritage and culture had been destroyed. A few months after the Mount St Helens eruption, some residents reported suffering emotional stress because of it.

Communities in the region asked for funding to help these people. The earthquake in Bam caused 9,300 people needing support for depression and post-traumatic stress disorder. If comparing both these events, we can clearly see that the earthquake in Bam had a bigger demographic and social impact than the Mount St Helens volcano because of the amount of damage and deaths that had taken place. These demographic and social impacts show how such events can have a huge effect on the people who suffer because of it.
