Primary waves,  also called P waves, secondary waves, also called S waves, and surface waves. These waves can travel through solids, liquids, and gases.  ]]> 2017-04-06 19:51:32 UTC https://padlet.com/876942/cy287ti2smt1/wish/165256343 How long do earthquakes last? 876942 https://padlet.com/876942/cy287ti2smt1/wish/165256679 Most of the time, earth quakes last only a few seconds. They usually last 10-30 seconds]]> 2017-04-06 19:53:17 UTC https://padlet.com/876942/cy287ti2smt1/wish/165256679 what should people do during an earthquake? 8778321 https://padlet.com/876942/cy287ti2smt1/wish/165256964 - Stay where you are until the quake ends

-move away from tall buildings, houses, and anything that can fall from a tall height.

- If you are out in the open, do not move until the shaking stops.

- If your phone is working, only use it in case of emergency.

- If you are in your house, do not move, because items may fall off of shelves, or out of cupboards.

-Listen to the radio for important information and instructions.

-If you leave your house, leave a message telling friends and family your location

In 1934, Charles Richter invented the Richter scale, (Pronounced Rick-ter) which is one of the ways that people measure the magnitude of an earthquake. The scale ranges from 1-10. Less than 2 is a micro earthquake. Above 6 is larger and stronger earthquake. Below that is moderate, then minor earthquakes.]]> 2017-04-06 20:18:13 UTC https://padlet.com/876942/cy287ti2smt1/wish/165260927 Where do Earthquakes Happen? 8778321 https://padlet.com/876942/cy287ti2smt1/wish/165260932 Most earthquakes occur along the sides of the ocean and continental plates. ]]> 2017-04-06 20:18:15 UTC https://padlet.com/876942/cy287ti2smt1/wish/165260932 Seismographs 876942 https://padlet.com/876942/cy287ti2smt1/wish/165472702 2017-04-07 20:18:23 UTC https://padlet.com/876942/cy287ti2smt1/wish/165472702 How earthquakes happen 997098 https://padlet.com/876942/cy287ti2smt1/wish/165473354 Earthquakes are usually caused when  underground rock suddenly breaks along a fault line. This  releases energy that causes the seismic waves that make the ground shake. ]]> 2017-04-07 20:24:53 UTC https://padlet.com/876942/cy287ti2smt1/wish/165473354 The Richter Scale 876942 https://padlet.com/876942/cy287ti2smt1/wish/165976185 2017-04-11 20:07:31 UTC https://padlet.com/876942/cy287ti2smt1/wish/165976185 997098 https://padlet.com/876942/cy287ti2smt1/wish/165976508 2017-04-11 20:09:59 UTC https://padlet.com/876942/cy287ti2smt1/wish/165976508 Earthquake Damage 997098 https://padlet.com/876942/cy287ti2smt1/wish/165976824 2017-04-11 20:11:55 UTC https://padlet.com/876942/cy287ti2smt1/wish/165976824
