Earthquakes

What is the epicenter of an earthquake?

• the location along a fault where the first motion of an earthquake occurs

• the point on Earth's surface directly above the earthquake's focus

• a seismic wave tht travels along the surface of Earth

• the last place that motion in an earthquake is detected

When seismologist record arrival times of P waves and S waves at several seismograph stations, they are looking for the earthquake's _____

• magnitude.

• epicenter.

• intensity.

• focus.

• pH Scale

• Mohs Scale

• Richter Scale

• Modified Mercalli Scale
