Vocabulary

 * Liquefacation**- occurs when an earthquakes shaking turns soft soil into liquid mud


 * aftershock**- an earthquake that occurs in a the same area a larger earthquake has occurred.


 * tsunamis**- large, monster waves created when an earthquake happens on the ocean floor


 * base**- isolated building- a base created to absorb the shock and energy an earthquake will give off, made with rubber layers so the building will sway during an earthquake[[image:file:///private/tmp/Untitled-1%20@%20100%25%20%28RGB%29.jpg]]

Outline

 * T= Earthquake Hazards and Safety**

1. How Earthquakes can cause damage 1. Making Buildings Safer
 * severe shaking of earthquake
 * damage/ destroy buildings[[image:GWBN2.3.jpg width="446" height="307" caption="A diagram of a fixed base and a base- isolated building and their reactions to an earthquake"]]
 * damage/ destroy bridges
 * topple utility poles
 * fracture gas
 * fracture water mains
 * s- waves
 * cause severe damage near the epicenter
 * put stress on buildings- fall apart
 * can trigger landslides = avalanches
 * local soil conditions
 * solid rock= less shaking
 * sandy soil= more shaking
 * liquefaction
 * creates cracks
 * shaking makes soil- mud
 * trigger landslides
 * aftershocks
 * earthquake that happens
 * in same area as bigger earthquake
 * Tsunamis
 * when earthquake hits ocean floor
 * makes monster waves- tsunamis
 * starts from oceans epicenter
 * can be as high as a six story building
 * New buildings= made more flexible+ stronger
 * Old buildings- modified to withstand earthquakes
 * Choice of location
