Project Details

Forecasting the size of future megathrust earthquakes and tsunamis by exploiting the new technology of offshore and onshore geophysical observations.
We aim to assess the potential for megathrust earthquakes in the coastal region of the Guerrero state by establishing the first Mexican seafloor geodetic and seismic network to obtain slow earthquake data. After analyzing the onshore data as well as the landward data, such as onshore GNSS* stations and seismic stations, we will develop scenarios for the earthquake and tsunami hazard, an earthquake/tsunami hazard map, and a tsunami evacuation sign to aid in safely evacuating the residents. The development of disaster education programs will help mitigate disasters with the inclusion of Mexican cultural perspectives and actions to be taken.　*GNSS: Global Navigation Satellite System

Utilization of the new knowledge on slow earthquakes to mitigate the disasters from future megathrust earthquakes and tsunamis
Understanding the similarities and differences between slow and megathrust earthquakes in Japan and Mexico will contribute greatly to understanding the fundamental physics of megathrust earthquakes and tsunamis in Japan’s Nankai Trough region as well as the Mexican subduction zone. Furthermore, initiatives aimed at mitigating damage in the event of a megathrust earthquake will aid in the sustainable development of Japanese society by ensuring the lives and belongings of citizens are protected in the event of a future megathrust earthquake centered in western Japan.
