It is not my fault
The crack in the earth's crust where potential energy is suddenly released causing an earthquake.
What is a fault?
These seismic waves can travel through all of the earth's layers or any state of matter and are the fastest.
What are P-waves (Primary waves)?
The part of an earthquake is where the rocks first begin to move.
What is the focus?
This is the scale used to measure the actual amount of seismic activity or magnitude of an Earthquake.
What is the Richter Scale?
Earthquakes are caused when too much of this has built up in rocks and they can no longer handle it.
At this type of fault, tectonic plates scrape past each other at a transform boundary.
What is a strike-slip fault?
These seismic waves travel only through solids and follow the primary waves.
What are S-waves (Secondary waves)?
The name of the location directly above the focus.
What is the epicenter?
This instrument measures and records earthquake waves.
What is a seismograph?
A wall of water created when an earthquake occurs in the ocean floor.
What is a Tsunami
Earthquakes occur along a fault in this layer of the earth.
What is the Lithosphere?
These seismic waves travel only across the the Earth's surface and usually cause the most damage.
What are surface waves?
Most earthquakes occur along these areas because their slow movement causes large amounts of stress to build up over time.
What are plate boundaries?
The scale used to measure an earthquake's intensity based on damage and impact on humans.
What is the Mercalli scale?
This many seismographs are required to determine the epicenter of an earthquake.
What is 3?
This type of fault is found where rocks are pulling apart resulting in one block of rock sliding downward in relation to the other.
What is a Normal Fault?
Definition: A movement or trembling of the ground that is caused by a sudden release of energy along a fault.
What is an earthquake?
In which part of an earthquake, the most damage occurs here
What is the epicenter?
This scale measure the total energy released by an earthquake and is an update to the Richter scale.
What is the Moment Magnitude?
San Andrea's fault is the result of which boundary
What is a Transform Boundary?
The reason some faults are found within a lithospheric plate instead of at a boundary.
What is when older plates have been incorporated into newer plates?
The difference in arrival time of these two waves help scientists determine the epicenter of an earthquake.
The tremors can occur hours, days, or weeks after the original earthquake.
What are aftershocks?
A 5.0 magnitude earthquake on the Richter scale is this many times stronger than a 3.0 magnitude earthquake.
What is 100?
A measure of the earthquake's strength
What is magnitude?
