One of the two main elastic body waves because it moves through the body of an object, unlike surface waves.
Moves ground up and down. In the Alaskan earthquake the S-waves triggered the following tsunami, and buildings to fall.]]> 2017-05-18 02:42:45 UTC https://padlet.com/iylafeist1/y007wl4fv0w1/wish/172476130 iylafeist1 https://padlet.com/iylafeist1/y007wl4fv0w1/wish/172476480 Primary, faster, and weaker waves. Push and pull movement. In the Alaskan earthquake the P-waves bent railroad tracks, and triggered landslides]]> 2017-05-18 02:45:18 UTC https://padlet.com/iylafeist1/y007wl4fv0w1/wish/172476480 iylafeist1 https://padlet.com/iylafeist1/y007wl4fv0w1/wish/172477827 Last night, March 27, 1964 a 9.2 Richter scale earthquake struck the coast of Alaska. So far over 131 dead have been counted and over 23 billion dollars in destruction has been made. Scientists have theorized that the cause of this tragic disaster is the result of the Pacific plate sub ducting under the North-American plate but research is still being conducted.The earthquake lasted approximately 4.5 minutes with disasters including landslides and tsunamis. The tsunamis caused by the earthquake ripped through the coast of Alaska then a trans-oceanic tsunami hit most of the Pacific coast. Some reports say that the waves were over 100 feet tall. As new information rolls in we can confirm that the epicenter was in Prince William Sound, Alaska about 15.5 miles below surface. This earthquake was very unexpected by everyone, the cities affected had almost no safety precautions, emergency plans, or hazards. We hope that everyone stays safe.

The Rayleigh wave named for Lord Rayleigh who proved this waves existence rolls the ground like an ocean wave.

Then you can draw a circle from that distance around the town. By doing this with various town the over lapping point is the epicenter]]> 2017-05-18 04:00:16 UTC https://padlet.com/iylafeist1/y007wl4fv0w1/wish/172482394 iylafeist1 https://padlet.com/iylafeist1/y007wl4fv0w1/wish/172482918 Epicenter- the point on Earth's  surface vertically above the focus of the earthquake.
