=What is an earthquake?= Do you know what an earthquake is? If not let me tell you. An earthquake is the shaking in the ground. The shaking is caused by moving rocks inside the earth they shear together. Earthquakes start deep inside the earth. The gap between to plates is called faults. That’s where most earthquakes happen

=How do scientists measure earthquakes?= Scientist measure earthquakes by using a seismograph. The zigzag lines that shows up on the paper are called seismograms. By using a seismograph they can tell the time of the earthquake, the depth, faulting, to tell how much energy was used, and the epicenter.

=What are seismic waves?= A **//__Seismic Wave__//** is actually a means of transferring energy from one spot to another within the earth. These waves come from the inner side of the earth. The only reason Earthquakes happen is because of the tectonic plates shear or rub against each other. This shearing causes earthquakes and the **//__Seismic Waves__//**. These waves cause a lot of damage .When Earthquakes occur they produce **//__Seismic Waves__//** the geologist study these //__Seismic Waves__// to see how big the earthquake is and what’s the damage going to be. **//__Seismic Waves__//** are vibration caused by Earthquakes due to moving plates.

=Where are many of the Earth’s earthquakes happening?= Today most Earthquakes occur in Baja California Mexico the magnitude is 3.5. Earthquakes happen because of plates crash together. The earliest one in California 1769 exploded it was one of the most know it was 48 kilo. Earthquakes can rate in the same rate as fingernails Scientist have worked to improve school safety. Some schools have collapsed and killed many of children and hurt and killed teachers. China mostly needs school improvement in there schools. Thousands of people have donated money to states for help. In California Earthquakes happen in 1-5 minutes an hour. Earthquakes are in the top 10 deadliest storms.

=What are scientists doing to try to predict earthquakes?= Scientist predict earthquakes by using a seismograph connected to each other to gather prediction. Scientist now days use lazars to find out how faults move. Scientist don’t predict earthquakes but they just find better infamation and call it predictions. To day scientist think one day they will be able to predict earthquakes. Scientist can get idea were earthquakes might happen.
