Waves
This is how seismic waves move
Up and down
Fractures in rock where sections of rock might suddenly move to create an earthquake
Fault
Force per unit area acting on a material
Stress
Fractures in rock where sections of rock might suddenly move to create an earthquake
Fault
These waves push and pull rocks in the same direction along which the waves are traveling
Primary waves
An earthquake on the ocean floor can produce
Tsunami
Causes permanent strain
Ductile Deformation
What type of fault is the San Andreas
Strike-slip
The most destructive waves produced by an earthquake are
Surface waves
When the ground behaves like a liquid
Liquefaction
What does the straight part of a stress-strain graph portray?
Elastic Deformation
Push and pull rocks in the same direction along which the waves are traveling
Primary waves
Describes the relationship between travel times of seismic waves from the earthquake's focus to a seismic station
P waves travel faster than S waves and take less time to reach the station
Which scale measures the damage done by an earthquake to determine an earthquake's intensity
Modified Mercalli Scale
If a tsunami develops during an underwater earthquake, what will most likely occur?
Severe destruction will occur in some coastal areas
The record produced by a seismometer
Seismogram
The study of how seismic waves change as they travel through Earth has revealed that
What is Earth's outer core is liquid because S-waves are not transmitted through this layer
Point on Earth's surface above the point where the strain is released
Epicenter
The most likely cause of earthquake activity on the West Coast of the United States
The slipping of tectonic plates
Where is the New Madrid Fault located
Bootheel of Missouri
