Finding data
This is when you take 3 seismograph station distances to find the epicenter
What is Triangulation
This is a pulse energy that travels quickly through the earth
What is a P-wave
This is the opening in a volcano through which magma is released
What is a vent
This force causes rocks on either side of a fault to slide past each other
What is shear
What is the focus
What is a thrust fault
This is the definition of elastic limit
What is the maximum amount of stress something can take before it breaks
This is the steep-walled depression around the vent
What is a crater
This force squeezes rocks together
What is compression
What is a Composite Volcano
This table calculates the amount of damage done by an earthquake
What is a modified mercalli scale
This is a seismic wave trapped near the surface of the earth
What is a surface wave
This is a large depression at the top of a volcano
What is a Caldera
This force pulls rocks apart
What is tension
This is the difference between the P and S waves
What is the S-P interval
This table calculates the magnitude of an earthquake
What is a richter scale
This is the definition of liquifaction
What is shaking making wet soil or not very hard solids into liquid
When poisonous gases get released from the volcano because the magma below releases gases while cooling
What is a Limnic Eruption
This is the rock above the fault
What is a hanging wall
This is why studying seismic waves help scientists map earth's interior?
Helps find out how dense and thin earth's interior is
This is when rocks layer up into a rainbow-like shape
What is an anticline
Why do scientists Classify volcanoes
Classifying a volcano assesses the risk
This is the force used in a normal fault
What is tension
This is the only fault type with no hanging or footwall
What is a Strike-slip
