Association for the Development of Earthquake Prediction ADEP Japan#
More than 146,000 high‐quality images of analog seismograms from several academic institutes and agencies in Japan are made available through a database hosted by the Association for the Development of Earthquake Prediction (ADEP, Tokyo, Japan). Participating institutions - Hokkaido University, Kyoto University, Tohoku University, University of Tokyo, and National Astronomical Observatory of Japan maintain the original records and copyright.
