vibration of earth produced by rapid release of energy
the point in earth where an earthquake starts
the point on the Earth's surface directly above the focus of an earthquake
fractures in earth where movement has occured
Elastic Rebound Hypothesis
explanation for the release of energy stored in deformed rocks
an earthquake that occurs after a larger earthquake in the same area
a small earthquake that often proceeds a major earthquake
a device that records ground movements caused by seismic waves as they move through Earth
the record of an earthquake's seismic waves produced by a seismograph
seismic wave that moves on earths outer layer
push and pull waves
A type of seismic wave that moves the ground up and down or side to side.
A measurement of earthquake strength based on the size of the area of the fault that moves, the average distance that the fault blocks move, and the rigidity of the rocks in the fault zone.
occurs when an earthquake's violent shaking suddenly turns loose soft soil into liquid mud
a giant wave caused by an earthquake on the ocean floor
an area along a fault where there has not been any earthquake activity for a long period of time
the outer layer of the Earth
the layer of the earth between the crust and the core
the solid part of the earth consisting of the crust and outer mantle
The lower layer of the crust, weak
The liquid layer of Earth made of nickel and iron.
solid, dense center of the Earth
the boundary between the earth's mantle and crust
