タイトル（英）：	SOURCE MODEL OF THE 2000 TOTTORI-KEN SEIBU EARTHQUAKE AND NEAR-SOURCE STRONG GROUND MOTION
抄録（英）：	Source process of the 2000 Tottori-ken Seibu, Japan, earthquake is studied by inverting combined data of strong motion records and geodetic data using the multiple time window linear waveform inversion method. This earthquake is comparable to the 1995 Hyogo-ken Nanbu (Kobe), Japan, earthquake in size, but different from the Hyogo-ken Nanbu earthquake, it did not occur along a known active fault. Additionally, it created only small-scale, intermittent surface ruptures but no clear one. However, the inverted source model shows large slip at small depth. It also suggests a possibility that the rupture progression was affected by the swarm activities in the past. Estimated near-source ground motion shows a complex pattern and is found to be strongly affected by heterogeneous rupture.
