Faults and Earthquakes

Front

What are P waves and what do they feel like during an earthquake?

Back

P waves, or primary waves, are the first seismic waves released during an earthquake. They are felt as small jolts and light shaking.

Front

What type of stress is associated with a normal fault?

Back

Tension is the type of stress associated with a normal fault.

Front

What is the focus of an earthquake?

Back

The focus of an earthquake is the point underground where the earthquake originates.

Front

What is the Richter Scale used for?

What type of stress is associated with a reverse fault?

Back

Compression is the type of stress associated with a reverse fault.

Front

What are S waves and how do they differ from P waves?

Back

S waves, or secondary waves, are seismic waves that arrive after P waves. They cause more intense shaking and can only travel through solids.

What is the difference between the epicenter and the focus of an earthquake?

Back

The epicenter is the point on the Earth's surface directly above the focus, which is the point underground where the earthquake originates.

Front

What is a fault in geological terms?

Back

A fault is a fracture or zone of fractures between two blocks of rock, which can cause earthquakes.
