San Andreas Earthquake by Matthew Bagley https://padlet.com/mattbagley23/fhi08xn2zp5s By: Matthew Bagley Hobbs P7 en-us 2017-05-11 22:51:02 UTC 2017-05-18 16:28:17 UTC hello@padlet.com P and S Waves mattbagley23 https://padlet.com/mattbagley23/fhi08xn2zp5s/wish/172583457 P waves are the very first waves to be recorded on the seismograph  because they are the fastest traveling waves. P waves move in a back and forth motion and are the least destructive wave. P waves can pass through liquids but all the other waves cant.
S waves are the second waves to be recorded on the graph. They move in a side to side direction which causes the earths ground to roll. Because of this movement, s waves are the most dangerous and destructive.

Surface Waves travel on the Earths surface. They are the slowest and the third wave to be recorded on the graph.

The Epicenter is on the surface directly above where the earthquake was.
To Find the Epicenter of an Earthquake you have to have three seismographs from different city's.Use your map and find how far away the epicenter is in centimeters. Once you have that done that draw a circle of how big the epicenter was away in centimeters around the city for all your city's. When all three circles meet you have your epicenter.

This is the Epicenter of the San Andreas earthquake.

The magnitude of the San Andreas fault was 6.8.

Mercalli scale is a scale that measures the intensity of an earthquake. It rates the Earthquake 1-12. the intensity of the Sand Andreas fault was 7.]]> 2017-05-18 15:06:52 UTC https://padlet.com/mattbagley23/fhi08xn2zp5s/wish/172605948 mattbagley23 https://padlet.com/mattbagley23/fhi08xn2zp5s/wish/172617612 2017-05-18 15:41:05 UTC https://padlet.com/mattbagley23/fhi08xn2zp5s/wish/172617612 Quake proof designs mattbagley23 https://padlet.com/mattbagley23/fhi08xn2zp5s/wish/172618059 There are many Quake proof buildings with great technology.
There is K and X braces that help keep buildings in tact during a quake.
There are base isolation systems like bearings sliding in little half pipes using gravity putting the building back in center. Or counterweights at the top of skyscrapers to keep the weight even. Many buildings have designs like this. ]]> 2017-05-18 15:41:54 UTC https://padlet.com/mattbagley23/fhi08xn2zp5s/wish/172618059 Quake Hazards mattbagley23 https://padlet.com/mattbagley23/fhi08xn2zp5s/wish/172618647 earthquakes have hazards such as
- Shaking
- Ground Rupture
- Landslides
Sometimes after quakes something much worse comes such as large fires or a tsunami. The fire of the Great San Francisco Earthquake killed more people than the earthquake itself. The San Andreas fault  had a terrible ground rupture.

They should also have flashlights, fire extinguishers, and extra food and water. The city should also have sirens when an Earthquake or tsunami happens and some type of shelter to keep the citizens safe.]]> 2017-05-18 15:54:30 UTC https://padlet.com/mattbagley23/fhi08xn2zp5s/wish/172622063
