Earthquake - is a feeble shaking to violent trembling of the ground produced by the sudden displacement of rocks or rock materials below the earth's surface.
Tectonicearthquake - generated by the sudden displacement along faults in the solid and rigid layer of the earth.
Volcanic Earthquake - earthquakes induced by rising lava or magma beneath active volcanoes.
Seismicwaves - slippage on fault = release of elastic energy transported by seismic waves which travel throughout the earth. we feel them as vibrations.
P Waves
Body Wave
Fastest
Push-pull movement
Can move through solid and fluid
S waves
Body Wave
Slower than P wave
Up & down, side to side movement
can only move through solid
SurfaceWaves
Travel Outward
Slowest
GroundShaking
Disruptive up-down and sideways movement or motion experienced during an earthquake.
Ground rupture - displacement on the ground due to movement of fault.
Liquefaction - Process that transforms the behavior of a body of sediments from a solid to a liquid when subjected to extremely intense shaking.
EARTHQUAKE-INDUCEDLANDSLIDE - MOVEMENT OF ROCK, EARTH, OR DEBRIS DOWN A SLOPED SECTION OF LAND CAUSED BY EXTREME SHAKING OF THE GROUND
Love Wave = Perpendicular
Rayleigh Wave = Parallel and Perpendicular
TSUNAMI - A.K.A SEISMIC SEA WAVE, IS A SERIES OF WAVES IN A WATER BODY CAUSED BY THE DISPLACEMENT OF A LARGE VOLUME OF WATER
