CoreLogic honors the long tradition of Japanese earthquake science by adhering to customary region-specific use of hazard parameters. The CoreLogic model adopts a view of hazard based on the December 2013 report released by the Earthquake Research Committee - Headquarters for Earthquake Research and Promotion (ERC-HERP) as implemented by the National Research Institute for Earth Science and Disaster Prevention (NIED) in the Japanese National Seismic Hazard Maps. New views of hazard including new seismic source zonation with earthquake ruptures cascading over multiple segments, updated maximum upper-bound magnitudes, and revised ground motion attenuation relationships with an improved nonlinear soil amplification model with a countrywide resolution of 250 meters.
This new, fully probabilistic and scenario earthquake tsunami flooding model is included as a sub-peril in the Japan Earthquake Model. Tsunami heights are computed using the Cornell University Multi-grid Coupled Tsunami Model (COMCOT), a state-of-the-art numerical model for all subduction interface and offshore crustal events of moment magnitude (M w) ≥ 7.0, including Nankai Trough, Sagami Trough, Japan Trench, Chishima/ Kuril Trench events, Izu-Bonin Trench events (many of which cause tsunami damage, but not shake damage due to the great distance from shore), Sea of Japan events, and relevant stochastic, historical, and scenario events.
