P waves (Primary waves)
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
vibrations that travel through Earth carrying the energy released during an earthquake
Breaks in Earth's crust where rocks have slipped past each other.
seismic waves that travel along the Earth's surface
a sudden and violent shaking of the ground, sometimes causing great destruction, as a result of movements within the earth's crust or volcanic action.
A wave that requires a medium through which to travel
travel through liquids and solids, push and pull, faster, arrive first
a wave in which matter moves back and forth in the direction the wave is moving
The study of earthquakes
travel through solids only; cause rock to move in a side-to-side or up & down motion, slower waves
The point beneath Earth's surface where rock breaks under stress and causes an earthquake
