What's New

Historical Seismograms Online

Scans of the Caltech Archive

We are pleased to announce that scanned images of historical seismograms from the Caltech archive are now publically available online at IRIS at:
http://www.iris.edu/seismo/projects/#caltech

This repository of images includes major historical global events as well as local records of the 1920's and 1930's. The images can be browsed in thumbnail size or downloaded for digitization at full resolution. Fuller documentation is available on the IRIS site. Please enjoy!

This scanning project was a collaboration with UC Santa Cruz and Google as part of the Google books project. Many thanks to the IRIS staff and Google collaborators who made this possible.
