It is not my fault
The crack in the earth's crust where stress is suddenly released causing an earthquake.
fault
These seismic waves can travel through all of the earth's layers or any state of matter:
P-waves (Primary waves)
Where an earthquake begins
focus
This is the scale used to measure the actual amount of seismic activity or magnitude of an Earthquake.
Richter Scale
Earthquakes are caused when too much of this has built up in rocks and they can no longer handle it.
pressure/stress
At this type of fault, tectonic plates scrape past each other at a transform boundary.
strike-slip fault
These seismic waves travel only through solids.
S-waves (Secondary waves)
The name of the location directly above the focus.
epicenter
This instrument measures and records earthquake waves.
seismometer/seismograph
A wall of water created when an earthquake occurs in the ocean floor this is called
Tsunami
Earthquakes occur along a fault in this layer of the earth.
Lithosphere
These seismic waves travel only across the the Earth's surface and usually cause the most damage.
surface waves
Most earthquakes occur along these areas because their slow movement causes large amounts of stress to build up over time.
plate boundaries
The scale used to measure an earthquake's intensity based on eyewitness observations.Based on destructions.
Mercalli scale
Most injuries and deaths from an earthquake occur due to the collapsing of these structures.
buildings
This type of fault is found where rocks are pulling apart resulting in one block of rock sliding downward in relation to the other.
Normal Fault
Definition: Vibrations in the ground that result from movement along breaks in the Earth's lithosphere
earthquakes
The most damage from an earthquake occurs here:
epicenter
This is the word that names how an earthquake is felt by people
intensity
Tall jagged lines would be found on this paper ____________ to show that an earthquake has happened
seismogram
At this type of fault, one block of rock slides upwards in relation to the other one as a result of them being pushed together.
Reverse Fault
Type of waves that travel perpendicular to the push pull motion. They can move through solids ONLY
Secondary Waves (S waves)
The tremors that follow major earthquakes as the Earth readjusts.
aftershocks
If an earthquake records a magnitude of 9.5, is this measurement recorded in the Mercalli Scale or Moment Magnitude scale?
Moment Magnitude
The location of the most powerful recorded earthquake in North America occurred in this state.
Alaska
The type of boundary in which two tectonic plates are moving toward each other - often locations of subduction and mountain building
convergent boundary
The waves that cause rock particles to move in a rolling (elliptical) motion
surface waves
The energy that is sent out in every direction from the focus of an earthquake
seismic waves
The word that means the measure of the DAMAGE an earthquake causes using the Mercalli Scale
intensity
This type of damage is common after earthquakes besides building destructions
fires, gas explosion
The type of boundary in which two tectonic plates are moving away from each other
divergent boundary
Part of an earthquake that receives the 1st wave
focus
A break in the Earth's Crust
Fault
Definition:A measure of the earthquake's energy
magnitude
The South American country, home to Valdivia, where one of the most powerful earthquakes occurred
Chile
The most dangerous type of fault
Reverse fault
The process when 3 circles meet to help locate the epicenter of an earthquake
triangulation
The boundary that causes earthquakes when plates slide past each other horizontally; like the San Andreas Fault
transform boundary
If a seismologist says that an earthquake has been felt by few people at rest; some suspended items may swing.
Which scale is being used?
Richter Moment Magnitude Mercalli
Mercalli scale
San Andrea's fault is the result of which boundary
Transform Boundary
