Earthquake
What Happens in an Earthquake?
It is when two blocks of earth slide over each other, the place where that happens is called a fault plane. The underground place where the earthquake starts is called the hypo center. The place directly above that on the surface is called the epicenter. http://earthquake.usgs.gov/learn/kids/eqscience.php

Here are three ways we can prepare for an earthquake.
1) Learn what to do during an earthquake. Hold periodic family drills to practice what you have learned.
2) In each room of your home, identify the safest places to “drop, cover, and hold on” during an earthquake.
3) List addresses, telephone numbers, and evacuation sites for all places frequented by family members (e.g., home, workplaces, schools). Include the phone number of an out-of-state contact.
