Geology Badge #16

Geology Badge #16
April 27th, 2016


For number 16, it wanted me to define eight different terms.  They are:

Focus: the point of origin of an earthquake
Dictionary.com: http://www.dictionary.com/browse/focus?s=t

Epicenter: Also, epicentrum. Geology. a point, directly above the true center of disturbance, from which the shock waves of an earthquake apparently radiate.
 Dictionary.com: http://www.dictionary.com/browse/epicenter?s=t

After Shock: A less powerful earthquake that follows a more forceful one. Aftershocks usually originate at or near the focus of the main earthquakes they follow and can continue for days or months. They usually decrease in magnitude and frequency with time.
 Dictionary.com: http://www.dictionary.com/browse/aftershock?s=t

Seismograph: any of various instruments for measuring and recording the vibrations of earthquakes.
Dictionary.com: http://www.dictionary.com/browse/seismograph?s=t

Richter Scale: a scale, ranging from 1 to 10, for indicating the intensity of an earthquake.
Dictionary.com: http://www.dictionary.com/browse/richter-scale?s=t

Surface Waves: a seismic wave that travels along or parallel to the earth's surface.
Dictionary.com: http://www.dictionary.com/browse/surface-wave?s=t

P Waves: a longitudinal earthquake wave that travels through the interior of the earth and is usually the first conspicuous wave to be recorded by a seismograph.
Dictionary.com: http://www.dictionary.com/browse/p--wave?s=t

S Waves: a transverse earthquake wave that travels through the interior of the earth and is usually the second conspicuous wave to reach a seismograph.
Dictionary.com: http://www.dictionary.com/browse/s-wave?s=t

Also the requirement asked if our area is prone to earthquake hazards like: landslides, ground rupture, shaking, liquefaction, or tsunamis.

Shaking- could not find anything about shaking for our state. If you find something about it, please post in the comment box.

The last question number 16 asked was:
What are the safety instructions for your area during an earthquake?
