| Zusammenfassung |
| The 2006 large interplate Kurile earthquake proved that the entire plate
interface of the Kurile-Kamchatka subduction zone was strongly coupled from
Hokkaido, Japan, to Kamchatka, Russia. The seismic moment of the 2006 Kurile
earthquake estimated from ten tsunami waveforms is 3.1×1021 Nm
(Mw=8.3). This estimate is consistent with the seismic moment estimated from the
seismological data in the Global CMT catalog. The computed tsunami
propagation indicates that scattering of the tsunami waves occurred at the
shallow region near the Emperor Ridge. The computed tsunami propagation also
indicates that large later tsunami waves observed at Crescent City is caused
by the shallow region along the Mendocino Fracture Zone. The seismic moment
of the 2007 outer-rise Kurile earthquake estimated from tsunami waveforms is
1.0×1021 Nm (Mw=8.0). This estimate is also consistent with the
seismic moment in the Global CMT catalog. |
