Hazardous Earth - Managing earthquake hazards

Question 1

Name some different ways to manage earthquakes

Answer 1

(1) Preparation - warning systems and evacuation // building design
(2) Long-term planning - training and funding emergency services
(3) Prediction - investing in technology
(4) Short-term relief - shelter and supplies

Question 2

What is needed after an earthquake

Answer 2

(1) trained volunteers to help injured people and clear debris
(2) Clean water to prevent spread of disease
(3) Food - as shops, transport and farms can be damaged

Question 3

In what ways can you strengthen a building

Answer 3

(i) Installing band of concrete at the roof level to stop walls falling outwards
(2) very strong framework in skyscrapers //strengthening walls
(3) making foundations from rubber and steel which can move slightly
(4) reinforcing gas and water pipes so they don’t break

Question 4

List 2 differences in the ways buildings are made earthquake resistant in poor and rich countries

Answer 4

(1) Rich countries have more money to spend on making earth-quake resistant buildings eg more rubber and steel foundations which can move slightly
(2) Buildings in poor countries more likely to be made with wood. A cheap way to make these buildings more earth-quake resistant is to add diagonal braces that reduce movement.

Question 5

Compare the short-term relief efforts after an earthquake in a rich vs poor country
