NESEC - Earthquakes Total Number of earthquakes in the Northeast, 15381989 4498. earthquakes in the Northeast US cannot be associated with specific known faults, http://www.nesec.org/hazards/Earthquakes.cfm
Extractions: 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 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.

Extractions: Search by Slide Number: Images of Historical Earthquakes The Jan T. Kozak Collection In 1996, under sponsorship of the Czech-American Science and Technology Cooperation Program, Dr. Jan Kozak, a geoscientist of the Institute of Rock Structures and Mechanics in Prague, Czech Republic , and the Earthquake Engineering Research Center Library of the University of California, Berkeley, digitized 875 slides of illustrations of historical earthquakes from Dr. Kozak's personal collection. Professor Bruce Bolt of Berkeley provided a preface suggesting historical, macro-seismological and artistic qualities of this Collection. A bibliography of historical sources developed at the EERC Library accompanies the collection. The images are accessible from an alphabetical table of countries or regions or a chronological list of earthquakes. Individual slide numbers can also be searched from this page. Questions about the collection and use of these images can be addressed to the EERC Library Dr. Kozak wishes to extend his thanks to many individuals and institutes [Kozak Collection] [Preface] [Location] ...

Extractions: Earthquakes Canada - West Sep 20: The forecast Episodic Tremor and Slip event continues on southern Vancouver Island. Tremor activity started at 01:00UT on September 03 on the Olympic Peninsula of Washington State and has now migrated northwest of Victoria to the vicinity of Cowichan Lake. Approximately 4 mm of reverse (westward) surface displacement was measured at on GPS instruments as the event passed beneath Victoria. See below for an explanation of ETS. Click here for an example of tremor on southern Vancouver Island seismographs.

Extractions: 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

Extractions: Earthquakes The California Geological Survey studies earthquakes to help Californians plan and build earthquake resistant communities. We record the strong ground motion from earthquakes, study the distribution of historic earthquakes and evaluate faults that are the source of earthquakes. We combine that information to prepare maps showing the potential for ground shaking, fault rupture, liquefaction and seismically induced landsliding. Maps of recent earthquakes and Shakemaps of the intensity of earthquake shaking are available from Trinet , a cooperative project of CGS, Caltech and USGS.
