this is the instrument used to detect earth waves
seismometer
subduction would most likely occur at this type of boundary
convergent
These two properties of a material allow it to change shape without breaking under stress
ductility and elasticity
this is the horizontal direction of a fault
strike
in the united states, most major faults are located near these geologic features
mountain ranges
a dip-slip fault is another name for this type of fault
reverse fault
these are secondary, smaller earthquakes that follow an earlier major earthquake
aftershocks
this instrument detects and records earthquake waves
seismograph
surface waves have two names, and these are those names
Rayleigh and Love Waves
each measure of on the Richter scale is this many times bigger than than the previous
almost 32 times more
This scale is the scale geologists use to report an earthquake to the public.
Richter Scale
this is an ocean waves created by an earthquake
Tsunami
this is a transform fault
strike-slip
this is the fastest body wave
P wave
this is a body wave that cannot travel through the earth's core
S wave
this is the center of earthquake activity
focus
this is the point on earth's surface above the center of earthquake activity
epicenter
the richter scale measures this, which is the indicator of the energy released by an earthquake
magnitude
the direction, in degrees from north, of a fault line
strike
the distance of the slanted face above a fault line
dip
this is the type of stress that is most significant in causing earthquakes
shear
this is a source of danger that can not change
hazard
this is the possibility of injury or death to people and damage to property that we can reduce or even eliminate
risk
this scale identifies the destructiveness of an earthquake
Modified Mercalli Intensity Scale
the amount of strain that a rock can handle without breaking is related to this property
ductility
