Analysis of seafloor seismograms of the 2003 Tokachi-Oki earthquake sequence for earthquake early warning
[1] Earthquake Early Warning (EEW) algorithms estimate the magnitude of an underway rupture from the first few seconds of the P-wave to allow hazard assessment and mitigation before the S-wave arrival. Many large subductionzone earthquakes initiate 50–150 km offshore, potentially allowing seafloor instruments sufficient time to identify large ruptures before the S-waves reach land. We tested an...
متن کاملFault friction parameters inferred from the early stages of afterslip following the 2003 Tokachi-oki earthquake
[1] We use subdaily GPS time series of positions in the first 5 hours following the 2003 Tokachi-oki earthquake (Mw = 8.0) located offshore of Hokkaido, Japan, to estimate frictional parameters for the afterslip zone on the subduction interface. The data show little motion immediately after the earthquake with sudden acceleration at about 1.2 hours after the main shock. This coincides with the ...
متن کاملElastic oscillations of water column in the 2003 Tokachi-oki tsunami source: in-situ measurements and 3-D numerical modelling
During the 2003 Tokachi-Oki tsunamigenic earthquake the real-time JAMSTEC observatory obtained records which provided a unique opportunity to have a look deep inside the tsunami source. Considering water column as a compressible medium we processed the bottom pressure records in order to estimate amplitude, duration and velocity of bottom displacement. Spectral analysis of the records revealed ...
متن کاملTsunami Generation of the 1993 Hokkaido Nansei-Oki Earthquake
-Heterogeneous fault motion of the 1993 Hokkaido Nansei-Oki earthquake is studied by using seismic, geodetic and tsunami data, and the tsunami generation from the fault model is examined. Seismological analyses indicate that the focal mechanism of the first 10 s, when about a third of the total moment was released, is different from the overall focal mechanism. A joint inversion of geodetic dat...
