=Click on our names to see what we have been doing in the lab!= =Agusta= =Carolyn= =Jackeline= AYME What is an earthquake? = An earthquake is a sudden release of stored energy. The energy has been stored for thousands and thousands of years. The earthquake is when to plates are stuck for many years and suddenly it is released and it causes the crust the crust to shake =

=How do scientists measure earthquakes?= The way scientists measure earthquakes is by using seismogram. A seismogram is a simulation it records earthquake waves and it shows how long it lasted and how powerful it is.

=What are seismic waves?= I think seismic waves are waves that happen during, after or before a earthquake appears. Seismic waves make the rocks vibrate to travel in every direction from the focus. Seismic waves move really fast and we can feel them when they reach the surface. Seismic waves travel underground also. They measure seismic waves with seismograph. =Where are many of the Earth’s earthquakes happening?= Even though we have no idea when earthquakes will occur we are still trying to figure out about more information about earthquakes. I think that earthquakes occur mostly in California but it could actually occur in the places you would never think it would happen. Transform faults are when two plates slide past each other it is rare. Earthquakes are very unpredictable. Less than 10 percent of earthquakes have been caused by plates interfering with each other. Earthquakes mostly occur in places where there is a fault line. When the plates rub against each other it makes an earthquake. =What are scientists doing to try to predict earthquakes?=
