UTIG researchers have deployed ocean bottom seismographs, deployed high resolution temporary networks, analyzed seismograms collected on the Moon, and helped plan seismometers to be deployed on Mars. Members of the UTIG staff have international reputations and travel throughout the world to conduct research and present results. Since Texas has no organization with a formal mandate to provide earthquake information, members of the UTIG scientific staff regularly answer questions asked by private individuals and commercial organizations that must make decisions abou Read More Go to Site Earthquakes - General Interest Publication Votes:0 Text Only Version Earthquakes by Kaye M.

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 Read More Go to Site Historic Earthquakes in Southern California Votes:0 Home Below is a clickable map of southern California, with epicenters of historic earthquakes (as far back as 1812) of particular note plotted over the background topography. Shown, too, are major highways (in tan) and the surface traces of major faults (in greenish-blue). This map does not show the epicenters of all earthquakes greater than magnitude 4.5 recorded in the southern California area since the 19th century. It is meant as an overview of large and destructive, fairly recent, or unusual earthquakes. The magnitudes given by the scale are generally moment magnitudes (denoted M w ), for earthquakes above magnitude 6, and local magnitudes (denoted M L ), for most earthquakes below magnitude 6 and for earthquakes which occurred before accurate instrumental measurements of magnitude we Read More Go to Site IDEERS Shaken Societies Votes:0 Quindio Date: 25.01.99 Magnitude: 5.9 ML Dead: 1,200 Injured: 8,500 Homeless: 90,000 Kobe Date: 17.01.95 Magnitude: 6.9 MW Dead: 5,500 Injured: 35,000 Homeless: 300,000 Izmit (Kocaeli) Date: 17.08.99 Magnitude: 7.4 MW Dead: 17,000 Injured: 44,000 Homeless: 600,000 Chi-Chi Date: 21.09.99 Magnitude: 7.5 MW Dead: 2,400 Injured: 11,000 Homeless: 100,000 Northridge Date: 17.01.94 Magnitude: 6.8 Ms Dead: 60 Injured: 9,000 Homes Destroyed: 25,000 Bhuj To be added soon.

I put up these pages moments after the Kobe earthquake happened in early 1995 when I got a few TV images from Japan through a friend on IRC (Internet Relay Chat). Now the information and many links on this pages are out of date , and much better information and images is available from the Kobe City itself on the net among other places. The web is not an archival medium: web pages move, and web pages are removed completely. Lesson: learned: if you put up information, please try use URLs that will work forever. Several people have written to me while studying the Kobe earthquake, so here are some additional pointers: Check the Kobe city home page mentioned above Do check your local library for issues of magazines such as Time, Newsweek etc published shortl Read More Go to Site Plate Tectonics, the Cause of Earthquakes Votes:0 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 boili Read More Go to Site Recent Earthquakes in California and Nevada - Index Map Votes:0 Home Relative2Me - Which earthquakes happened near you?

Schulz and Robert E. Wallace The presence of the San Andreas fault was brought dramatically to world attention on April 18, 1906, when sudden displacement along the fault produced the great San Francisco earthquake and fire. This earthquake, however, was but one of many that have resulted from episodic displacement along the fault throughout its life of about 15-20 million years. What Is It? Scientists have learned that the Earth's crust is fractured into a series of "plates" that have been moving very slowly over the Earth's surface for millions of years. Two of these moving plates meet in western California; the boundary between them is the San Andreas fault. The Pacific Plate (on the west) moves northwestward relative to the N Read More Go to Site The Southern Arizona Seismic Observatory Votes:0 The Southern Arizona Seismic Observatory No Frames Version click here Read More Go to Site The World-Wide Earthquake Locator Votes:0 Quake Animation Quake Prediction Catalogue Query Quake Mapping Current Quake Report Home THE WORLD-WIDE EARTHQUAKE LOCATOR QUAKE REPORT Find out about the latest earthquakes around the world.
