Seismograms of the 1948 Fukui (Japan) Earthquake:
The following seismograms were scanned at 600 dpi, on either 8-bit gray scale or 1-bit black- and-white from two publications: Central Meteorological Observatory (1948) and Office of the Engineer (1949).
For station and instrument information, please consult: �Principal seismographs used in JMA Seismological Observation Network since 1875, a history of the observation�, released on a CD-ROM by the Japan Meteorological Agency, 2002.
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 600 dpi resolution.
Seismograms are organized by station as follows, and each seismogram has annotation on it.
