location of earthquakes
causes of earthquakes
faults at tectonic plates boundaries
earthquake wave
earthquake mesurment
100
focus
the point along a fault at which the first motion of an earthquake occurs
100
siesmology
the study of earthquake
100
earthquakes
can happen both near earths surface or far be low it
100
seismic waves
waves of energy that travel through the earth are called
100
s-p time method
they use the.........method to find an earthquakes epicenter
200
horizontal axis
an earthquake can be found by reading the.....
200
stress
as tectonic plates push pull or slip past each other what increases along faults near the the plates edges
200
tectonic plate boudaries
most earthquakes happen in the earthquake zones along
200
primary waves
p waves are also called
300
vertical axis
tells how much time passed between the staart of the earth quake and the arrival of seismic waves at a station
300
rubber band pieces
elastic rebound is like the return of the broken what does it compare itself to.
300
earthquake zones
are places where a large number of faults are located
300
secondary waves
another word for s waves is
300
richter
wanted to compare earthquakes by measuring ground motion recorded by seismograms at seismograph stations
400
seismographs and seismogram
how do seismologist know when and where earthquake begin?
400
released
during elastic rebound energy is what?
400
strike-slip faults
transform motion creates
400
surface waves
move the grond much like ocean waves move water particles
400
seismograms
can be used not only to determine an earthquakes epicenter and its start time but also to find out an earthquake strength
