Study Notes

Prediction

Though earthquakes cannot be predicted, scientists can warn people of impending danger.
Monitoring floods and landslides are ways scientists can try to keep people safe.
Records of past earthquakes are kept to predict future ones.
Scientists estimate the amount of tension that builds along fault lines.
As tension increases, so does the likelihood of an earthquake occurring.
Earthquake Early-Warning Systems (EEWS) monitor seismic activity.
EEWS exists to warn people of upcoming disasters.
The goal of EEWS is to allow people time to reach a safer location.

Preparation

Collapsing walls, flying glass, and falling objects cause most earthquake casualties.
Governments try to ensure buildings and structures can withstand earthquakes.
Stronger building materials are used in earthquake-prone areas to keep people safe.
People practice earthquake drills where natural disasters are common.
People who are indoors during an earthquake should take shelter under a sturdy desk/table or in a load-bearing doorway.
Stay away from windows, outside walls, or anything that could fall on you.
Stay in one place until the shaking has completely stopped.
