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 does the earthquake begin?
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?
Two plates converge, continental and oceanic. Which one goes down?
Oceanic
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.
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 Earth's surface and usually cause the most damage.
surface waves
Most earthquakes occur along these areas because the 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
Subduction zone
Definition: A movement or trembling of the ground that is caused by a sudden release of energy along a fault.
earthquakes
This is the point above the focus on the surface. The most damage occurs here.
epicenter
This is one example of what is measured by scientists when they try to figure out the strength of an earthquake. Starts with an "i."
intensity
This is when a large amount of soil and rock slips down an incline.
Landslide
This is the type of plate boundary at which you find older crust.
Convergent plate boundary
Type of waves that travel across the surface like a snake (side to side).
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
These waves are the fastest.
P-waves
Definition: Vibrations that causes different types of ground motion
seismic waves
This is what the seismograph prints out.
Seismogram
This type of damage is common after earthquakes - besides building destructions
fires, gas explosion, road damage
The type of boundary in which two tectonic plates are moving away from each other
divergent boundary
Origin of an earthquake
focus
Definition: A break in the Earth's Crust
Fault
Definition:A measure of the earthquake's energy
magnitude
Name the country in which the most powerful earthquake occurred in South America
Chile
This is a geographic location at which you find the most earthquakes and volcanoes.
Ring of Fire
This is how many recording stations are needed to determine the location of the earthquake.
3
The boundary that causes earthquakes when plates slide past each other horizontally; like the San Andreas Fault
transform boundary
What scale is been used Richter, Moment Magnitude or Mercalli? If a seismologist says that an earthquake has been felt by few people at rest; some suspended items may swing.
Mercalli scale
San Andrea's fault is the result of which boundary
Transform Boundary
