In cooperation with Incorporated Research Institutions for Seismology (IRIS)


Coordinated by Michael F. Diggles and William H.K. Lee

This is a site where seismologists and geophysicists worldwide can share scans of analog seismograms; these will be curated and archived at IRIS (Incorporated Research Institutions for Seismology) at the University of Washington as time permits. This work is funded by IASPEI (International Association of Seismology and Physics of the Earth’s Interior).

“... old seismograms, if properly interpreted, provide invaluable information on earthquakes in the past, and every effort should be made to save them, regardless of their quality, from possible loss and to make copies in an easily readable form.” —Hiroo Kanamori (1988)


Donated seismograms are available in these folders:
