Answer:

1.Earthquakes are usually caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two blocks of rock or two plates are rubbing against each other, they stick a little. They don't just slide smoothly; the rocks catch on each other.

2.seismograph is the primary earthquake measuring instrument.

3.earthquakes occur around the edges of the Pacific Ocean, an area known as the 'Ring of Fire'; this where the Pacific plate is being subducted beneath the surrounding plates. The Ring of Fire is the most seismically and volcanically active zone in the world.

4.earthquakes and volcanoes are not directly related. Of course earthquakes happen in these subduction zones, but they do not really cause eruptions. Nonetheless, in very specific conditions, earthquakes and volcanic activity are indeed connected.

5.If you are in a car, pull over and stop. Set your parking brake.

If you are in bed, turn face down and cover your head and neck with a pillow.

If you are outdoors, stay away from buildings.

Answer:

1. An Earthquake is what happens when two blocks of earth suddenly slip past one another. Earthquakes are usually caused when rock underground suddenly breaks along a fault. This sudden release of energy caused the seismic waves that make the ground shake.

2. Seismographs and Mercalli Scale.

3. Pacific Ocean

4. Volcanic Eruptions occur when either plates sink below another plate, heating and creating a magma, or plates pull apart, allowing magma to rise to the surface. Thus, volcanic eruptions can cause earthquakes because of the massive amount of energy that is released during an eruption.

5. Do the duck, cover, and hold. For extra precautions, prepare the needed things beforehand incase of a sudden earthquake.
