Vocabulary

Earthquakes and Tsunamis
Earthquakes are caused by the release of built-up pressure at plate boundaries.
Number of earthquakes in S Korea, 2000-2022
The Power of Plate Tectonics
earthquakes are happening all the time, on land and in the ocean. Most are so small that people don't even feel them.

Fault Line
A crack in the earth's surface where two tectonic plates meet.
Richter Scale
Scale to measure the strength of an earthquake.
Seismic Wave
Energy waves that travel through the earth, caused by earthquakes or explosions.
Tremor
Small or short movement of the earth's surface
Epicenter
The place where an earthquake is strongest
After Shock
A small earthquake or tremor following a larger quake.

Impact

WHO: Earthquakes
Earthquake Effects
An earthquake in itself, is not dangerous, however, the effects of that earthquake on the surrounding environment such as buildings and other manmade structures can be catastrophic.
Impacts of an Earthquake
When a large earthquake occurs, usually it is after the shaking stops that the major problems occur.

Predicting and Monitoring

How are earthquakes detected?
A seismogram is a record of the ground motions caused by seismic waves from an earthquake.
Designing earthquake-proof buildings
Why do countries struggle?
why aren’t more buildings designed to withstand shaking – even extreme shaking?
Prediction, Preparation and Protection
Experts know where earthquakes are likely to happen. However, it is very difficult to predict when they will happen.
