Transcript of Earthquakes
could have learned more Warranted international aid
& a halt in national activities How It Happened Damage Things We've Learned The Chilean Earthquake Facts 6 fore shocks larger than 6.0
Biggest was 8.1
Plates moved 20-30m past each others
Focal depth 33km (21 miles)
Magnitude of 9.6
Hit at 7:11 pm
about 160km off the Arauco Peninsula
Started with gentle rocking instead of usual abrupt start
Parked cars rocked
Earthquakes like this happen once every 300 years Figures Tsunamis The earthquake stimulated countries around the Pacific
They set up an international tsunami warning system
Deposits left by the tsunami could be studied by geologists
They can use the deposits to hypothesize where other tsunamis might occur of 1960 jg,luyt gilu b glyjdhgdjghj;hgjfgdfsdssdfp[rewewexfl[;]

$500 million of damage
1/3 of Valdiva (city) houses destroyed
Over 2 million homeless Richter Scale Measures magnitude of earthquakes
How bad they are
How much damage they could cause
From .1 to 10
Method made by American C. F. Richter Logarithmic Increases tenfold each time the scale increases
1, 10, 100... Thank You For Watching! And now...
a short video! The Earthquake Came Too Soon Along with Alaskan earthquake of 1964 Seismologists say if it had come a little later, we could have learned a lot more
