- Estimation of actual activity rate-changes from seismic catalogs with systematic missing measurements: Aftershock activity of the M6.5 Noto Peninsula earthquake:
- For the purpose of online early prediction, we dared to consider all of the detected aftershock data and tried to analyze the aftershock activity immediately after the May 5 M6.5 earthquake. As a result, an interpretation was proposed that fluid pressure may have increased after the main shock and then converged to explain the change in background seismic activity level.
