The direction seismic waves travel.

What is all directions?

The fastest of the seismic waves

What is a Primary wave?

Only travels through solids

What is secondary wave?

Measures and records seismic waves

What is a seismograph?

The point within the earth where the energy is first released.

What is the focus?

Expresses the intensity of an EQ

What is the mercalli scale?

Measures the amount of energy released during an EQ

What is the Richter scale?

Complete destruction

What is XII on the Mercalli scale?

Can be used to find distance from an epicenter if lag time is known

What is a travel time graph?

Zones of immobile rock along faults

What are seismic gaps?

Vibration of the earth’s crust

What is an EQ?

Most EQ happen here

What are on plate boundaries?

Two plates moving toward each other

What is a convergent boundary?

3 types of boundaries EQ occur

What is convergent, divergent, transform?

Theory used to explain EQ

What is the elastic rebound theory?

The minimum number of stations needed to find an epicenter

What is 3?

Body of water formed by diverging plates

What is the Red Sea?

Largest fault in CA

What is the San Andreas?

The 3 EQ zones

What are Pacific Ring of fire, Mtn belt, Mid. Atl. ridge?

Area around the Pacific Ocean noted for EQ and Volcanic activity

What is the Pacific Ring of Fire?

The safest part of the house in an EQ

What is a doorway?

Where you should not go if there is an EQ

What is outside?

Food, water, radio, flashlight, and batteries

What are things to keep in case of an EQ?

Water, gas and power

What are things to shut off after an EQ?

Person responsible for enlightening you about EQs

Who is Ms Wessel?
