Tsunamis Earthquakes and Volcanoes

The point on the earth’s surface directly above the origin of the earthquake.

• Epicenter

• Focus

• Foreshock

• Caldera

A tool used to measure and record earthquake activity

The most destructive seismic waves. They move the earth side to side and up and down.

• P waves

• L waves

• S waves

• X waves

Do two colliding continental plates always cause volcanoes?

• No, earthquakes always occur when two continental plates collide

• Yes, subduction always occurs when continental plates collide

• No, usually no subduction occurs when continental plates collide
