Volcanoes & Earthquakes Test

What does the diagram show as relating to locating an earthquake epicenter?

• It is possible to determine the depth of the earthquake through the use of three epicenters.

• Three is not a sufficient number of seismic stations to locate an earthquake epicenter.

• This is an example of using triangulation to correctly pinpoint an epicenter.

• Only one of the three circle radius readings is needed. The other two are simply to check the location determined from the first.

Earthquakes result from the ________ release of elastic energy previously stored in rocks surrounding a zone of ________ movement.

• rapid; wave

• rapid; fault

• slow; wave

• slow; fault
