Management can reduce the effects of tectonic hazards.
Why do people live in tectonic areas and how are the possible effects being managed?Slide2
Why do people live in tectonic areas?
In pairs discuss:
Which area of the world has the highest number of people potentially affected by tectonic activity?
Why may some of these areas have higher death tolls caused by tectonic activity than other areas? Slide3

What have they done in Nepal and New Zealand?

New Zealand
Management and co ordination of open spaces
Introduced strict building regulations so buildings can withstand earthquakes.
Go bags –
survival kits
Old buildings have bee retrofitted.

Exam practice-Evaluate the strategies used to manage earthquakes and volcanoes (6).
The three p’s are used to try to reduce the impacts of earthquakes and volcanoes. Earthquake warning systems can be used to detect earthquakes but only after an earthquake has begun which will not give enough time for people to prepare and evacuate. As a result this system is not effective however the data from these systems can be used to try and predict when the next earthquake will happen.
Tiltmeters
can be used to detect any changes in the earth’s crust which normally happen before a volcanic eruption. This allows people time to close up their homes and evacuate. Buildings can be designed to with stand earthquakes, this is called retrofitting. This can be successful but only normally happens in
MEDC’s
where there is the money available to buy these materials or reinforce older buildings…………
