内容記述 | The Earthʼs surface is influenced continuously by natural forces such as tides, air pressure, and precipitation, as well as human-induced sources. To separate the geodetic strain of trend components from these induced responses, state-space modeling is applied to volumetric strain data recorded with borehole Sacks-Evertson strainmeters, which have been operated by the Japan Meteorological Agency (JMA) since 1976 in the area of an expected Tokai earthquake. Modeling reveals that no pre-slips occurred just before the earthquake at Suruga-bay in 2009 (M 6.5), regardless of the clear trend components extracted at all stations. Coseismic strains at stations within and near the coastal area indicate extension, despite the contraction field predicted from the inversion of strong motions. This suggests that fluid movement is stimulated by variations of water volume, which are caused by seismic motions changing pore pressure in the sand layer. Liquefaction in the same area supports this hypothesis. Moreover, normalized trend components suggest that long-period waves of strain changes still exist, inducing further strain responses. Such information may provide a breakthrough in geodetic studies of the area. | |||||
