Major achievements
Kenji Satake has led research on the mechanism and history of occurrence of giant earthquakes and giant tsunamis around the world using geophysical, historical and geological approaches. He developed a method to estimate tsunami sources using tsunami waveforms and numerical simulations, and investigated the magnitude and slip distribution of giant earthquakes in subduction zones around the world. He showed that tsunami earthquakes that generate larger tsunamis than seismic waves have larger slip at shallow plate boundaries near the trench axis. Based on Japanese historical records and tsunami simulations, he found the timing and magnitude of the latest giant earthquakes in the Cascade subduction zone in North America. Furthermore, by combining tsunami deposit survey and tsunami simulation, he showed that giant earthquakes occurred in the 17th century in the Kuril Trench and in the 9th century in the Japan Trench (Jogan Earthquake) before the 2011 Great East Japan Earthquake. He also made significant contributions to the domestic and international communities through his efforts in the establishment and management of AOGS (Asia Oceania Geosciences Society) and its journal, Geoscience Letters.
