100
Shearing, compression, and tension are three types of this.
What is stress?
100
This produces synclines and anticlines.
What is folding of the crust?
100
This is what occurs when water is displaced by an earthquake under the ocean.
What is a tsunami?
100
This type of building design decreases the amount of energy that reaches the building during an earthquake.
What is base-isolated?
100
This is a large area of land elevated high above sea level.
What is a plateau?
200
Geologists locate this by drawing circles to show distances from three seismograph stations.
What is the epicenter?
200
This is a rating system that estimates the total energy released by an earthquake.
What is the moment magnitude scale?
200
This type of stress pushes rock sideways in opposite directions.
What is shearing?
200
This is the point on the Earth's surface directly above an earthquake's focus.
What is the epicenter?
200
These waves arrive after P waves.
What are S waves?
300
This is any change in shape or volume of the Earth's crust.
What is deformation?
300
At a seismograph, these waves arrive first.
What are P waves?
300
This happens when loose soil turns into mud.
What is liquefaction?
300
This fault forms when the hanging wall moves upward past the footwall.
What is reverse?
300
This stress force produces a strike-slip fault.
What is shearing?
400
This is an instrument that measures and records ground movements during an earthquake.
What is a seismograph?
400
Slabs of rock slip past each other in this break in the crust.
What is a fault?
400
Anticlines and synclines are two types of these.
What are folds?
400
This force pulls on the crust and stretches rock.
What is tension?
400
This is the point beneath the Earth's surface where the crust breaks and triggers an earthquake.
What is the focus?
500
This force squeezes rock at a reverse fault.
What is compression?
500
This bounces a laser off the ground to detect slight movements.
What is a laser ranging device?
500
This uses a wire strung across a fault.
What is a creep meter?
500
This scale measures intensity of earthquakes based on people, buildings, and land.
What is the Mercalli scale?
500
This scale measures the size of seismic waves.
What is the Richter scale?
