Tectonics - Case Studys

Question 1

Intraplate example, and its regional impacts

Answer 1

1990 Bishops Castle. Pontsford-Linely fault. 5.1 magnitude felt in April. Some places in Shrewsbury suffer power outages, collapsed roofs and chimneys.

Question 2

Hot Spots from mantle plumes, example.

Answer 2

Hawaii.

1. Isolated plumes of convecting heat, called mantle plumes, rise towards the surface, generating basaltic volcanoes that tend to erupt continuously.
2. A mantle plume is stationary, but the tectonic plate moves slowly over it.
3. Over millennia, this produces a chain of volcanic islands, with extinct ones most distant from the plume’s location.

Question 3

Natural hazard in a developed region, PROFILE

Answer 3

Japan 2011. 9.0 earthquake, followed by a 9m tsunami. Pacific plate subducted beneath the Japan plate, destructive plate boundary that causes water column displacement. Ground shaking, liquefaction, landslides.

Question 4

Natural hazard in a developed region, REGIONAL/GLOBAL INFLUENCE

• US issued an advisory for Americans not to travel to Japan. Lots of money lost from tourism
• Stock Markets around the world were affected.
• Share prices insurance companies feel as they may face huge losses

Question 5
