The shaking that results from the movement of rock beneath Earth's surface.
the theory that Earth's crust is broken up into continent size plates, which move over the mantle.
a series of smaller earthquakes that occur after a large earthquake in the same area.
waves that vibrate from side to side. They cannot move through liquids.
The 1st waves to arrive during an earthquake. They compress and expand the ground. They can move through solids, liquids, and gases.
the slowest moving seismic wave. They make the ground roll violently. They cause the most damage to buildings.
The measurement of an earthquake's strength based on seismic waves and movement along faults.
describes the damage an earthquake has on people, structures, and the natural environment.
The point beneath Earth's surface where rock breaks under stress and causes an earthquake
Point on Earth's surface directly above an earthquake's focus
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
vibrations that travel through Earth carrying the energy released during an earthquake
A scientist who studies seismic waves caused by explosions, drilling, for natural resources, and earthquakes.
A giant wave usually caused by an earthquake beneath the ocean floor.
The process by which an earthquake's violent movement suddenly turns loose soil into liquid mud
A scale that rates an earthquake's magnitude based on the size of its seismic waves.
A scale that rates earthquakes according to their intensity and how much damage they cause at a particular place
where the edges of two plates meet. Most earthquakes and volcanoes occur along these boundaries.
how high or low a wave swings on a seismograph.
The method used to find the epicenter of an earthquake using the readings of 3 different seismic stations.
graph used to plot the arrival times of p-waves and s-waves
The thin and solid outermost layer of the Earth above the mantle
The layer of hot, solid material between Earth's crust and core.
A dense sphere of solid iron and nickel at the center of Earth
the liquid layer of the Earth's core that lies beneath the mantle and surrounds the inner core
