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).
