1caused by the sudden and rapid movement
earthquake
2large volumes of rocks along the fractures of the earth's surface
faults
3types of fault
strike slip, normal fault (60°) reverse fault (30°)
4the earth's outermost shell,crust,and uppermost mantle consists of moving
tectonic plates
5the plates separate and the energy stored in rocks is released in
seismic waves
6types of seismic waves
body waves & surface waves
7measures the energy released by an earthquake
magnitude
8measures the effect of the earthquake
intensity
9types of strike slip faults
sinistral (left) dextral (right)
10strike slip faults consists of
hangingwall and footwall
11occurs when the ground loses stiffness
liquefaction
12liquefaction process
shaking, sediment compression and squeezing out of fluids, pore water pressure
13factors affecting liquefaction
duration, geology, proximity to the fault, intensity of shaking, density of infrastructure
14effect of liquefaction
flooding and sandboil
15landslide is also known as
mass wasting
16the downslope movement of rocks or sediments under the influence of gravity
landslide
17what happens before a landslide
weathering
18earthquake induced landslide
strength of the earthquake, distance from the fault, topography, climate, characteristics of soil or rocks.
19landslide warning signs
cracks and bulges in the road, increased soil content in streams, leaning poles or walls, a rumbling sound that grows louder, unusual sounds such as cracking trees

21a series of giant waves
tsunami
22which japanes word does tsunami translates to?
"harbor wave" tsu as in "harbor" and nami "wave"
23tsunami prediction and detection
open-ocean buoys, tide gauges, sensors, earthquakes
24natural signs of impending tsunamis
prolonged and severe ground shaking, receding sea level, loud "roaring", a huge incoming wall of water
