Seismograms of the 1964 Great Alaska Earthquake:

  • (Last updated: November 5, 2004)
  • ------------------------------------------------------------------------------------
  • 3/28 03:36 UTC  61.01N  147.62W  6km deep  Mw=9.2, Prince William Sound, Alaska*
    ------------------------------------------------------------------------------------

The following seismograms were scanned at 400 dpi, 8-bit gray scale by Ronsin Imaging Services, Inc. (215 S. Lemon Creek Drive, Walnut, CA 91789, USA), in August of 2004,  from selected WWSSN
film chips under the USGS/ICSU Scanning Project funded by the International Council of Scientific Unions.

For rapid viewing, the edited image files were saved in this Website at large "quality" reduction in PDF format, but the original scanned image files are archived at IRIS Data Center for download at the scanned 400 dpi resolution.

Seismograms are organized by station as follows, with the following abbreviations for components:
      LPZ = Long Period, Vertical component;  LPN = Long Period,  North-South component;  
LPE = Long Period, East-West component.
For each station, the WWSSN number, station code, coordinates (latitude in degrees, longitude in
degrees, and elevation in meters), and geographical location are given first.  The available seismograms
are then listed by station code and component (with start time given by month, day, year, ‘_’, hour, minute).

For station information, please click:  WWSSN1964.pdf: An extensive summary of the World-wide
Standardized Seismograph Network, including detailed description of all WWSSN stations.
