Source Process of the 2006 Oita-Chubu Earthquake (Mw6.4) Occurring in the Philippine Sea Slab
Abstract eng: We investigate source characteristics of a moderate-size intermediate-depth earthquake (MW6.4) occurring on 12 June, 2006 at a depth of about 145km in the Philippine Sea slab subducting beneath the Kyushu district, Japan. First we investigate rupture process from waveform inversion of strong ground motion and teleseismic body wave data. The result shows complex source process of this earthquake. We extract two asperities form the inversion result. Next we estimate the short period level of S-wave acceleration source spectrum. Estimated short period level is consistent with typical level estimated from other intraslab events, which is higher than that of crustal and interplate earthquake. 2006 Oita-chubu earthquake, intraslab earthquake, waveform inversion, spatio-temporal slip distribution, asperity model
