Earthquakes

Front

What scale rates the size of the seismic waves?

Back

Richter scale measures the amplitude of seismic waves.

Front

What type of stress causes a strike-slip fault?

Back

Shearing stress causes a strike-slip fault.

Front

How many seismograph stations are needed to pinpoint an epicenter?

Back

Three seismograph stations are needed to accurately locate an epicenter.

Front

What scale rates the damage suffered during an earthquake?

Back

The Mercalli scale rates the damage caused by an earthquake.

Front

What is a region in Earth's crust that is broken and where movement occurs?

Back

A fault is a region in Earth's crust where movement occurs.

Front

What are seismic waves?

Back

Seismic waves are waves of energy that travel through the Earth, typically caused by earthquakes.

Front

What is the focus of an earthquake?

Back

The focus is the point within the Earth where an earthquake originates.

Front

What is the epicenter of an earthquake?

Back

The epicenter is the point on the Earth's surface directly above the focus of an earthquake.

Front

What is the difference between the Richter scale and the Moment Magnitude scale?

Back

The Richter scale measures the amplitude of seismic waves, while the Moment Magnitude scale measures the total energy released by an earthquake.

Front

What is an aftershock?

Back

An aftershock is a smaller earthquake that occurs after a larger earthquake in the same area.
