Plate Tectonics
 Websites presented in alphabetical order 2005 Silent Earthquake and Deep Tremor 
 Background information and updates on the 2005 slow earthquake and deep tremor occurring in the Pacific Northwest in September 2005. This earthquake, which affected southern British Columbia and Northern Washington state, is the "predicted 'tremor and slip event' which is related to the movement of the Juan de Fuca and North America tectonic plates along the Cascadia margin of southern British Columbia." From the Pacific Northwest Seismograph Network at the University of Washington. http://www.pnsn.org/NEWS/PRESS_RELEASES/TREMOR_05.html Topics: Geography, Geology Last updated Sep 22, 2005 Earth Like a Puzzle
Explores plate tectonics. Contains information on spreading centers, what happens when plates collide, and the layers of the earth. Includes maps. From the Scripps Institution of Oceanography, University of California, San Diego. http://www.sio.ucsd.edu/voyager/earth_puzzle/ Topics: Geology, Mysteries and More Last updated Mar 19, 2006 The Earth's Ring of Fire
An overview and map of this area circling the Pacific Ocean. "The zone — the 'Ring of Fire' — notorious for frequent earthquakes and volcanic eruptions, coincides with the edges of one of the world's main tectonic plates. More than half of the world's active volcanoes above sea level are part of the ring." From the British Broadcasting Corporation (BBC). http://news.bbc.co.uk/2/hi/136248.stm Topics: Geography, Geology Last updated Sep 8, 2009 EarthScope
This site provides information about the project that uses "modern ... technologies to investigate the structure and evolution of the North American continent and the physical processes controlling earthquakes and volcanic eruptions." Learn about projects such as the drilling of a borehole into the San Andreas Fault, and read reports on the progress of research. "EarthScope is sponsored by the National Science Foundation and conducted in partnership with the US Geological Survey." http://www.earthscope.org Topics: Astronomy, Geology, Science, Science Last updated Sep 6, 2004 The Educational Multimedia Visualization Center (EMVC)
This site features dozens of computer animations and visualization tools about geologic changes. Includes animations about global tectonics (such as Pangaea and Mesozoic subduction), regional plate tectonics (with an emphasis on California), Ice Age earth (including the deglaciaton of North America), Craters of the Moon National Monument in Idaho, and more. From the Department of Earth Science, University of California, Santa Barbara. http://emvc.geol.ucsb.edu/ Topics: Geology Last updated May 11, 2009 Geology: Plate Tectonics
Contains an overview of plate tectonics theories (including information on Alfred Wegener), a description of the mechanisms driving plate tectonics, and animation illustrating the positions of the continents during various geologic time periods. From the Museum of Paleontology, University of California, Berkeley. http://www.ucmp.berkeley.edu/geology/tectonics.html Topics: Geology Last updated Aug 9, 2003 Paleomap Project
"The goal of the PALEOMAP Project is to illustrate the plate tectonic development of the ocean basins and continents, as well as the changing distribution of land and sea during the past 1100 million years." Earth History displays maps of the continental arrangements throughout the various geologic periods including future projections. Climate History displays climatic maps for each period. http://www.scotese.com/ Topics: Geology, Scientific Themes Last updated Oct 2, 2004 This Dynamic Earth: The Story of Plate Tectonics
This site provides "a brief introduction to the concept of plate tectonics," and "highlights some of the people and discoveries that advanced the development of the theory and traces its progress since its proposal." Includes illustrations. Online edition of a book "originally published in paper form in February 1996." From the U.S. Geological Survey (USGS). http://pubs.usgs.gov/gip/dynamic/ Topics: Geology Last updated Mar 12, 2006 |
