Seismology Sites

Reflection Seismology
  • Reflection Seismology at the University of Arizona 
      • This site gives a bit of insight into the academic applications of reflection seismology with its summaries of recent research at the university. It also manages to give a quick overview of 3-dimensional seimic data.

  • Univ. of Technology, Delft 
      • The previous web site is an excellent location for understanding practical applications of improving seismic data. The web site will explain the implementation of bilinear time-frequency representations in the interpretation of seismic reflections. The time-frequency representations presents the seismic reflection in a clear pattern thus providing useful interpretations of the subsurface lithology.

    • Earthquake Seismology

  • Earthquake at Alumn Rock 
      • On May 21, 1996 at 1:50PM, the Rapid Earthquake Location Service in Menlo Park and U.C. Berkeley Seismographic Stations, in Berkeley, California registered an earthquake of magnitude 4.7. It struck the Calaveras Fault 10 miles east of San Jose, California at a depth of 7.8km. The earthquake was produced by lateral strike slip movement. This seismic event is consistent with the horizontal motion of other earthquakes on the Calaveras Fault and fits in a pattern of several other earthquakes in this area.

  • Harvard University 
      • Harvard seismic data base provides the user with quick daily information on the latest world wide major earthquake events, along with detailed information on the Southern California area. The system has several earthquake location systems that compile a list of the latest events, with information such as magnitude, depth, time,... These earthquake locations are plotted on a global map that displays several options such as zooming on location, longitude, latitude,...

  • Institute of Seismology-Helsinki
      • This is an extensive site on earthquake seismology. It has tons of waveform data. The downside is that it's all in X-window format. But, hey!! We can handle that, right? Although it only covers north European activities, it seems very educational. All the waveform data is in compressed GSE1.0 format. The page also includes a very interesting post of all recorded earthquake activity from 1375 AD to present.

  • IRIS
      • The Incorporated Research Institutions for Seismology is a university research consortium dedicated to exploring the Earth's interior through the collection and distribution of seismographic data. The IRIS Data Management Center (DMC) is located in Seattle, Washington, just off the University of Washington campus. The IRIS DMC receives earthquake and seismic data from a variety of Data Collection Centers and is responsible for the long term archive and distribution of all IRIS generated data. The IRIS DMC website distributes earthquake data sets and reports in a variety of formats, as well as related software. There is also a good listing of other seismology related sites.

  • Ocean Seismic Network Pilot Experiment 
      • The goal of the Ocean Seismic Network (OSN) Pilot Experiment is to deploy for a three-month period an observatory-grade seismometer in a case borehole (OSN-1 aka ODP 834B, 225 km SSW of Oahu) and to simultaneously compare the data with broadband instruments lined up at and directly beneath the sea floor. One of the objectives of the experiment will be data collection which will assist in determining the structure of the Hawaiian swell. The project results may help answer questions about the Hawaiian upper mantle, plume and lithosphere structure.

  • Southern Ontario Seismic Network
      • The Southern Ontario Seismic Network provides information about the seismic hazards in Southern Ontario since 1991. Six seismic stations are operated by the University of Western Ontario for Ontario Hydro (this company owns nuclear power plants in that area). 

      This web site provides a seismicity map of Southern Ontario as well as a list of recent earthquakes, including location, magnitude, waveform plots. A list of major teleseismic events recorded by the SOSN (nuclear tests for example) and a list of recent Canadian events can also be found.

  • UCLA 
      • UCLA Southern California seismicity homepage allows access to a wide range of information based upon earthquakes in the Los Angeles Basin. Individual earthquakes are shown on detailed maps with their magnitude, location and type of faulting recorded. In addition, photographs of the damage caused during individual events are shown. Particular attention is focus on the Northridge earthquake with an impressive 3D animation displaying epicenter, fault location and topography.

  • University of Nevada 
      • This site, run by the University of Nevada, Reno, includes a wide variety of information on earthquakes both local and worldwide, and offers links to earthquake related pages. In addition, there is access to earthquake archives and catalogs, as well as information about the Nevada Seismological Laboratory and its staff. 

      The "Earthquake Information Page" within the site features listings of recent earthquakes, press releases for major earthquakes, fault maps, and locator maps for both local and global events. A unique feature for people who have been through an earthquake is an on-line form that they can fill out with descriptions of their experience. Another interesting item is an up-to-the-minute live picture of an analog earthquake drum seismogram showing current seismic activity.

  • USGS National Earthquake Information Center 
      • The U.S. Geological Survey has produced an excellent earthquake seismology web site for its National Earthquake Information Center. The NEIC works to determine quickly the magnitude and location of earthquakes worldwide, to provide a comprehensive seismic database, and to conduct research on locating and understanding earthquakes. This web page provides both current and general seismicity information, including a variety of maps showing size and depth of seismic events. The general seismicity section also uses graphics and text to explain such subjects as earthquakes, plate tectonics, and magnitude scales. Online information and information about NEIC products and services are also available.

    Other Hyperlink Listings for Seismology
  • Surfing the Internet for Earthquake Data 
      • "Surfing the Internet for Earthquake Data" by Steve Malone provides internet connections where original seismic data or seismic research information is available. The information presented is easy to read and very pertinent to earthquake seismology. "Special News Items" regarding the annual conferences and AGU meetings is also available. Sites for "Physics of Earthquakes", "Seismic Hazard Mapping", "Deep Earthquakes and Physical and Geochemical Processing" and "Active Hawaiian Volcanoes" are also offered. Detailed attention is given to each topic. Global or Composite earthquake catalogs, maps and data providing at least 200 links are also accessible from this page.
