EARTHQUAKES

P WAVES Go through anything Primary waves Appears first Fast but weak

S WAVES Cant go through liquids Secondary waves Strong, but slow Moves side to side

FOCUS Earthquakes origin Spreads everywhere

EPICENTER Right above the focus At the earths surface

During earthquakes Buildings collapse Hide in doors till it stops Find a clear spot to hide Stay away from windows

After earthquakes Aftershocks Fires and Tsunamis Check for injuries Inspect house Help trapped people

SURFACE WAVES Slowest waves Love waves Rayleigh waves Travel along the earths surface

WHICH PLACE HAS THE MOST EARTHQUAKES? WHY? JAPAN FIJI INDONESIA Theyre on the ring of fire fault line

How to measure a magnitude Richter scale Increases 31-fold every whole number

How to locate an epicenter Three seismograph stations Where the stations meet

Which came first? P waves S waves

The P wave

Which is stronger? P Waves S Waves Love Waves

S Waves

I. EARTHQUAKES Get at least three seismograph stations and pinpoint where they meet Three of the most powerful waves are love, p waves, and s waves. S waves are the strongest Japan, located near the ring of fire

I.EARTHQUAKES Strength of an earthquake is 31-times stronger each whole number During an earthquake stay away from windows, find safe spot to hide After earthquake watch for aftershocks, fires, and tsunamis. Check for injuries.
