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 کاملSurface latent heat flux and nighttime LF anomalies prior to the Mw=8.3 Tokachi-Oki earthquake
Surface Latent Heat Flux (SLHF) is an atmospheric parameter proportional to the evaporation from the Earth’s surface. SLHF has been found to exhibit an anomalous behavior in the epicentral region prior to several coastal earthquakes. Sub-ionospheric low frequency (LF) radio sounding measurements have shown its potentiality for the short-term earthquake forecasting since the last decade. The ano...
متن کاملA State-Space Approach to Explore the Strain Behavior before and after the 2003 Tokachi-Oki Earthquake (M8)1
The Earth’s surface is under the continuous influence of a variety of natural forces and human induced sources. Strain data are good examples of such disturbed signals. To determine the geodetic strain behavior before and after the 2003 Tokachi-oki earthquake (M8.0), we decomposed the disturbed strain data into trend, air pressure, earth tide, and precipitation responses components. The decompo...
