Earthquake Hazard Mitigation Measures for Individuals: Click here for resources and tools to support earthquake mitigation. What is an Earthquake? An earthquake is a sudden rapid shaking of the earth caused by the breaking and shifting of rock beneath the earth's surface. Earthquakes can cause buildings and bridges to collapse, disrupt gas, electric and phone lines, and often cause landslides, flash floods, fires, avalanches, and tsunamis. Larger earthquakes usually begin with slight tremors but rapidly take the form of one or more violent shocks, and end in vibrations of gradually diminishing force called aftershocks. The underground point of origin of an earthquake is called its focus; the point on the surface directly above the focus is the epicenter. The magnitude and intensity of an earthquake is determined by the use of scales like the Richter scale and the Mercalli scale Back to Top History of Earthquakes in New England: The average person may not associate earthquakes with the eastern portion of the United States, yet some of the largest seismic events have occurred east of the Rocky Mountains. In fact, the recorded history of earthquakes in the New World began shortly after the Pilgrims landed, when in 1638, a damaging earthquake rocked Plymouth Colony.

FUNDAMENTALS OF PHYSICAL GEOGRAPHY HOME FUNDAMENTALS ONLINE TEXTBOOK GLOSSARY ... ABOUT CHAPTER 10: Introduction to the Lithosphere (m). Earthquakes Introduction An earthquake is a sudden vibration or trembling in the Earth. More than 150,000 tremors strong enough to be felt by humans occur each year worldwide. Earthquake motion is caused by the quick release of stored potential energy into the kinetic energy of motion. Most earthquakes are produced along faults tectonic plate boundary zones , or along the mid-oceanic ridges Figures 10m-1 and ). At these areas, large masses of rock that are moving past each other can become locked due to friction . Friction is overcome when the accumulating stress has enough force to cause a sudden slippage of the rock masses. The magnitude of the shock wave released into the surrounding rocks is controlled by the quantity of stress built up because of friction, the distance the rock moved when the slippage occurred, and ability of the rock to transmit the energy contained in the seismic waves . The San Francisco earthquake of 1906 involved a 6 meter horizontal displacement of bedrock. Sometime after the main shock wave

We combine that information to prepare maps showing the potential for ground shaking, fault rupture, liquefaction and seismically induced landsliding.
