[SSS32-02] Triggering process of the M6.4 Eastern Shizuoka earthquake on March 15, 2011
Keywords:2011 Eastern Shizuoka earthquake, 2011 Tohoku-oki earthquake, static stress changes, dynamic stress changes, triggering
We investigated the triggering process of the MJMA6.4 Eastern Shizuoka earthquake which occurred near Mt. Fuji at a depth of about 14 km, four days after the Mw9.0 2011 Tohoku-oki earthquake. The Eastern Shizuoka earthquake may have been triggered by the static stress changes from the 2011 Tohoku-oki earthquake and/or the dynamic stress and strain changes due to the passage of surface waves from the MJMA6.2 Fukushima-oki earthquake which occurred about 230 sec earlier and at a site located about 400km away.
