Earthquake vocabulary
With a base-isolated building design the amount of energy that reaches the building during the earthquake
What is reduced?
This is a large area of flat land that is elevated high above sea level
What is a plateau?
Two types of folds
What are anticlines and synclines?
This fault forms when the hanging wall moves upward past the footwall
What is a reverse fault?
The type of stress that pushes masses of rock sideways in opposite directions
What is shearing?
S waves arrive at a seismograph after these waves
What is P waves?
This is the point beneath Earth's surface where the crust breaks and triggers an eathsquake
What is the focus?
This stress force pulls on the crust and stretches rock
What is tension?
Compression, tension, and shearing are these 3 types of what that causes changers in the crust
What is stress?
Water displaced by an undersea earthquake may produce these
What are tsunamis?
This is the first seismic wave to the seismograph
What are P waves?
This process occurs when an earthquake's shaking turns loose soil into mud
What is liquefication?
This scale is a rating system that estimates the total energy released by an earthquake
What is a moment-magnitude scale?
By drawing circles to show distances from three seismograph stations, geologists can locate this of an earthquake
What is the epicenter?
This force on a rock changes its shape or volume
What is stress?
This is a break in the crust where slabs slip past each other
What is a fault?
This is the point on Earth's surface directly above an earthquake's focus
What is an epicenter?
This process is when the crust produces anticlines and synclines
What is folding?
This instrument is used to measure and record ground movements during an earthquake
What is a seismograph?
This is the type of stress force that produces a strike-slip fault
What is shearing?
