Earthquake 1
The type of fault that occurs due to shearing stress where rocks on either side of the fault surface move past each other.
What is a strike-slip fault?
The type of wave that moves through Earth by causing particles of rock to move at perpendicular to the direction of the wave travel.
What is an S-wave?
The fault that results when the hanging wall is pushed above the footwall.
What is a reverse fault?
Waves that cause rock to stretch and compress traveling parallel to the direction of the wave.
What is a primary wave?
The rock that lies above the fault line.
What is the hanging wall?
Mathematical term that describes how on the Richter scale each whole number increase represents a ten-fold increase in magnitude.
What is logarithmic?
Using distance information from at least three seismic stations to locate the epicenter of an earthquake.
What is triangulation?
The stress that squeezes rocks.
What is compression?
A geological formation due to compression stress that causes an upward fold in the rock.
What is anticline?
The rock that lies below the fault line.
What is the footwall?
The stress that causes rock to stretch and elongate.
What is tension?
The scale that measures the damage caused by an earthquake.
What is the Mercalli Scale?
Stress that is a result of two plates sliding past each other.
What is shearing?
What happens to the amount of time between primary and secondary waves as they get farther from the epicenter.
What is the time becomes longer (or greater)?
The type of fault where the hanging wall slips below the footwall.
What is a normal fault?
The point on the Earth's surface directly above the earthquake focus.
What is an epicenter?
A geological formation due to compression stress that causes a downward fold in the rock.
What is syncline?
