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.
