2.6 Reducing the risk from tectonic hazards

Question 1

What is Monitoring?

Answer 1

➢ Using scientific equipment to detect warning signs of events such as volcanic eruptions

Question 2

What is Prediction?

Answer 2

➢ Using historical evidence to predict when and where a tectonic hazard will occur

Question 3

What is Protection?

Answer 3

➢ Designing buildings that will withstand tectonic hazards

Question 4

What is Planning?

Answer 4

➢ Identifying and avoiding places most at risk

Question 5

How can volcanoes be monitored?

Answer 5

➢ Remote sensing - Satellites can detect heat and changes to the volcano’s shape
➢ Gas - Amount of gas released as magma rises
➢ Seismicity - Seismographs record earthquakes

Question 6

How can volcanic activity be predicted?

Answer 6

➢ Using historical evidence scientists can roughly figure out areas greatest at risk

Question 7

How can places be protected from volcanoes and earthquakes?

Answer 7

➢ Earth embankments to divert magma
➢ Shock absorbers to absorb ground shaking in buildings
➢ Open areas for easy evacuations

Question 8

How can you plan for tectonic hazards?

Answer 8

Identifying areas great at risk and warning people in the area
