Earthquakes LAST

Front

What are S-waves?

Back

S-waves, or secondary waves, are seismic waves that cause the most damage during an earthquake. They move through the Earth after P-waves.

Front

What are P-waves?

Back

P-waves, or primary waves, are the first seismic waves to arrive after an earthquake. They are compressional waves that can travel through solids and liquids.

Front

What is an earthquake?

Back

An earthquake is the shaking of the Earth's crust caused by the release of energy in the Earth's lithosphere.

Front

What is the magnitude of an earthquake?

Back

The magnitude of an earthquake is a measure of the energy released during the event, commonly measured on the Richter scale.

Front

What causes tsunamis?

Back

Tsunamis are caused by underwater disturbances such as earthquakes, landslides, and volcanic eruptions.

Front

What is the epicenter of an earthquake?

Back

The epicenter is the point on the Earth's surface directly above where an earthquake originates.

Front

What is a fault?

Back

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

Front

What are Rayleigh waves?

Back

Rayleigh waves are surface seismic waves that cause the ground to move in an elliptical motion, often resulting in significant damage.

Front

What is the difference between S-waves and P-waves?

Back

S-waves are slower and can only travel through solids, while P-waves are faster and can travel through both solids and liquids.

Front

What is seismic energy?

Back

Seismic energy is the energy released during an earthquake, which travels in waves through the Earth.
