​Active volcanoes - Volcanoes that are currently erupting or are expected to erupt

​Dormant volcanoes - Volcanoes that are currently inactive but may erupt in the future.

​Describe 3 features of fold mountain.

​Narrow summit.

​

​Steep-sloping sides.

Multiple Choice

• Shallow-focus earthquake 

• Deep-focus earthquake 

Multiple Select

Identify the preparedness measures that people put in place to cope with tsunamis.

• Land use regulation

• Infrastructure

• Emergency drills

• Earthquake monitoring and warning systems

• Tsunami monitoring and warning systems

​Landuse regulation for tsunamis

​Landuse regulations are a set of rules implemented to restrict developments in certain areas.

​

​Prohibition of constructing new buildings on low-lying land which are vulnerable to tsunamis.

​- Developments may only be allowed when protective barriers such as seawalls are constructed

​Seawalls

​- Reduces speed of tsunami, decreasing the impact of tsunami on coastal areas.

​EMERGENCY DRILLS FOR TSUNAMI

• Get to high ground as far inland as possible.

• Listen to emergency information and alerts.

• Evacuate: DO NOT wait! Leave as soon as you see any natural signs of a tsunami or receive an official tsunami warning.

​INFRASTRUCTURE FOR TSUNAMI

​Build structures with reinforced concrete instead of wood, even though wood construction is more resilient to earthquakes.

Reinforced concrete or steel-frame structures are recommended for vertical evacuation structures.

​

​Construct deep foundations, braced at the footings. A tsunami's force can turn an otherwise solid, concrete building completely on its side, substantive deep foundations can overcome that
