| タイトル： | Seismic source characterization defined by minima of local recurrence time before the 2003 MJ8.0 Tokachi-Oki Earthquake" |
| 要旨： |
We specify the most likely locations of asperities in the Tokachi-Oki rupture plane and compare their places, sizes and numbers to suggested asperities defined by strong-motion modelling. We used the technique of mapping local recurrence time (TL) based on the declustered microseismicity that is homogeneous for MJ8.0 during 1997-2003. We mapped TL in the rupture area bounded by 41.5°-42.8° latitude and 143°-144.9° longitude. TL is the probabilistic estimate of recurrence time, calculated from the a- and b-values. |
