Transcript of Earthquakes

Cole Strahle,Devin Nitschmann,Dean Yankowicz

How Earthquakes are measured/recorded
Plate boundaries are made up of many faults. Since the edges of the plates are rough, they get stuck together. When the plate edges unstick from the faults, it sends up seismic waves, causing an earthquake.
How Earthquakes are Formed
Earthquakes can cause buildings to collapse, and those buildings can crash on top of people and anything that's under it, and they can split ground in half. Some earthquakes can crumble whole cities and towns, killing hundreds, and usually injuring lots more.
Why Earthquakes are so Dangerous
Famous Earthquakes in History
Before- Make sure you have a fire extinguisher, first aid kit, a battery powered radio, a flashlight, and extra batteries. Don't leave heavy objects on the shelves. Get down so you don't get knocked over.
During- If you are inside, stay inside and hide under something sturdy like a table. If outdoors stay outside and and get away from any structures or buildings that could collapse on you.
After-Check if you or anyone that is near you are hurt. If you have a first aid kit help whoever is hurt. If not, find one or find something that you can wrap aound the place where it is hurt. Check for any smell of gas, if you smell it, get out. Try and where shoes so you don't get cut and get away from building for the after shocks.

How to Prepare for an Earthquake
Fun Facts
Tetonic Plates
- Huge layers that make up the earth's upper layer.
- Weak lines that develop in the plates.
Seismic Waves
- Waves that travel through the earth during earthquakes.
- Greatness of size or amount.
Plate Boundaries
- Edges of the Tectonic plates.

Key Terms
Earthquakes are recorded or measured by the richter scale. It is a formula based on amplitude of the largest wave record on a specific type of seisometer and the distance between the Earthquake and the seisometer.

Interview by Michael Reed. 19 Oct. 2015: n. pag. Print.
There are 20 to 40 earthquakes occur everyday but most are not big enough to go on the news.
The most extreme Earthquakes occur near plate boundaries.
There are such things as moon quakes, earthquakes that occur on the moon.
There are 3 million earthquakes recorded every year.
The largest earthquake recorded in the U.S was in Prince William Sound, Alaska, it had a 9.2 magnitude.
San Fransico- 1906,7.8 magnitude, 3,000 + killed, $500,000,000 in damage, It took 4 years to recover, Bulidings instantly crumbled to pieces

Chile- 1960, 1,655 killed, magnitude of 9.5, $550,000,000, took 3 years to fully recover, the grounds ripped open, houses riped apart, deaths occured very quickly. It was the biggest earthquake that hit earth.

Shaanxi- 1556, magnitude of 8.8,3,000 killed or injured,$525,000,000 in damage, took 4 and a half years to recover, the ground ripped opened extremly quick
