Plate Tectonics, the Cause of Earthquakes The plates consist of an outer layer of the Earth, the lithosphere , which is cool enough to behave as a more or less rigid shell. Occasionally the hot asthenosphere of the Earth finds a weak place in the lithosphere to rise buoyantly as a plume, or hotspot. The satellite image below shows the volcanic islands of the Galapagos hotspot. (from NASA) Only lithosphere has the strength and the brittle behavior to fracture in an earthquake. The map below locates earthquakes around the globe. They are not evenly distributed; the boundaries between the plates grind against each other, producing most earthquakes. So the lines of earthquakes help define the plates: (from the USGS) In cross section, the Earth releases its internal heat by convecting, or boiling much like a pot of pudding on the stove. Hot asthenospheric mantle rises to the surface and spreads laterally, transporting oceans and continents as on a slow conveyor belt. The speed of this motion is a few centimeters per year, about as fast as your fingernails grow. The new lithosphere, created at the ocean spreading centers, cools as it ages and eventually becomes dense enough to sink back into the mantle. The subducted crust releases water to form volcanic island chains above, and after a few hundred million years will be heated and recycled back to the spreading centers. Earthquake occurrence in different plate tectonic settings: The map below of Earth's solid surface shows many of the features caused by plate tectonics. The oceanic ridges are the asthenospheric spreading centers, creating new oceanic crust. Subduction zones appear as deep oceanic trenches. Most of the continental mountain belts occur where plates are pressing against one another. The white squares locate examples given here of the different tectonic and earthquake environments.

Tsunamis & Earthquakes At The USGS General information from the United States Geological Survey on how local tsunamis are generated by Category Science Earth Sciences Geology Geologic Hazards Tsunami......General information on how earthquakes generate tsunamis and summariesof tsunami research using animations and VRML models. http://walrus.wr.usgs.gov/tsunami/

Below you will find general information on how local tsunamis are generated by earthquakes as well as animations, virtual reality models of tsunamis, and summaries of past research studies. The scope of tsunami research within the USGS, however, is broader than the topics covered here. USGS researchers have also provided critical research toward understanding how sediments are transported during tsunami runup (see, for example, analysis of deposits (1.8 MB) from the recent Papua New Guinea tsunami) and deciphering the geologic record of prehistoric tsunamis (for example, in the Pacific Northwest ). The USGS also collaborates with the tsunami research group at NOAA . As part of this effort under the National Tsunami Hazard Mitigation Program , the USGS has upgraded the seismograph network and communication functions of the west coast tsunami warning system (termed CREST Consolidated Reporting of EarthquakeS and Tsunamis). For further information select one of the topics below. Other tsunami sites are listed on the links page The Basics: Life of a Tsunami (56 kB) Tsunamis in the U.S. Pacific Northwest

HOME WHAT'S NEW ABOUT ACOUSTIC EMISSION DECI NEWSLETTERS AND REPORTS ... PUBLICATIONS BY H.L. DUNEGAN Prepared for presentation at "6th Conference on AE/MS Activity in Geologic Structures and Materials" Pennsylvania State University June 11-13, 1996. PREDICTION OF EARTHQUAKES WITH AE/MS? WHY NOT H.L. Dunegan May, 1996 INTRODUCTION Earthquakes account for more loss of life and property than any other natural phenomena. In spite of this fact, and the fact that we know why and how earthquakes occur, there is a great deal of pessimism from both the scientific community and Government agencies concerning one's ability to accurately predict earthquakes. This pessimism is evidenced by the large amount of funds expended in earthquake preparedness programs compared to the funds available for research concerning earthquake prediction. The primary reason for the lack of an earthquake prediction model is the inability of low frequency surface mounted seismic instrumentation to detect the higher frequencies associated with small fractures that occur prior to a large movement of a fault. The high frequencies associated with these small events are attenuated by the upper mantel and never make it to the surface. Once the higher frequency events due to small fractures occurring from a fault are detected, it is proposed that the data be handled in a fashion similar to that used for acoustic emission data from man made structures. Therefore some discussion of the procedures used for handling acoustic emission data will be presented, and analogies drawn to their use for earthquake prediction.

FEMA FOR KIDS: EARTHQUAKES The Federal Emergency Management Agency (FEMA) is in charge of helping people before and after a disaster Category Kids and Teens School Time Geology earthquakes......earthquakes happen along fault lines in the earth’s crust. earthquakes canbe felt over large areas although they usually last less than one minute. http://www.fema.gov/kids/quake.htm

Shake With The Quake Story Rumble Tumble Story ... Earthquake Legends arthquakes are the shaking, rolling or sudden shock of the earth’s surface. Earthquakes happen along "fault lines" in the earth’s crust. Earthquakes can be felt over large areas although they usually last less than one minute. Earthquakes cannot be predicted although scientists are working on it! Most of the time, you will notice an earthquake by the gentle shaking of the ground. You may notice hanging plants swaying or objects wobbling on shelves. Sometimes you may hear a low rumbling noise or feel a sharp jolt. A survivor of the 1906 earthquake in San Francisco said the sensation was like riding a bicycle down a long flight of stairs. he intensity of an earthquake can be measured. One measurement is called the Richter scale. Earthquakes below 4.0 on the Richter scale usually do not cause damage, and earthquakes below 2.0 usually can’t be felt. Earthquakes over 5.0 on the scale can cause damage. A magnitude 6.0 earthquake is considered strong and a magnitude 7.0 is a major earthquake. The Northridge Earthquake, which hit Southern California in 1994, was magnitude 6.7. Earthquakes are sometimes called temblors, quakes, shakers or seismic activity. The most important thing to remember during an earthquake is to DROP and COVER. Drop and cover means to DROP to the floor and get under something for COVER.

Hazards Assistance Flood Maps NPSC ... Hazards Earthquakes Search FEMA Hazards Dam Safety Earthquakes Extreme Heat ... Mitigation Division Earthquakes 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. This shaking can cause buildings and bridges to collapse; disrupt gas, electric, and phone service; and sometimes trigger landslides, avalanches, flash floods, fires, and huge, destructive ocean waves (tsunamis). Buildings with foundations resting on unconsolidated landfill, old waterways, or other unstable soil are most at risk. Buildings or trailers and manufactured homes not tied to a reinforced foundation anchored to the ground are also at risk since they can be shaken off their mountings during an earthquake. Earthquakes can occur at any time of the year. ( More Information What Should I Do? Before The Earthquake Strikes Protect Your Property During An Earthquake After The Earthquake Preparedness Information Preparedness planning involves those efforts undertaken before an earthquake to prepare for or improve capability to respond to the event.
