5- Measures Taken In Tectonic Areas

Question 1

What is the disaster risk equation

Answer 1

Risk = frequency or magnitude x vulnerability
————————————-
Ability to cope + adapt

Question 2

What is the park model

Answer 2

Graph to show quality of life before during and after event

Question 3

Name 2 types of building designs to reduce impact of tectonic activity

Answer 3

Rubber shock absorbers in building foundations

Steel frames which can sway during earth movement

Question 4

Why has number of natural disasters changed over time

Answer 4

Population growth and high population densities in tectonically active areas

Question 5

Why do some people mistakenly think the number of earthquakes and volcanoes is increasing

Answer 5

Improved monitoring and detection + increased media coverage

= for earthquake activity to increase there would need to be an increase in radioactive decay in earths core

Question 6

Name 2 possible future strategies to tackle tectonic events

Answer 6

Reduce poverty

Not possible to predict when a event will happen = improve forecasting

Falling buildings account for greatest cause of death = improve building design

Question 7

Why are high energy events less often

Answer 7

energy build up for longer time = larger gap/interval between events
