Heterogeneous crustal deformation along the Central-Northern Itoigawa-Shizuoka Tectonic Line Fault System, central Japan Reviewed

Earth Planets Space Vol. 56 ( 12 ) page： 1247-1252 2004.12

Authorship：Lead author Language：English Publishing type：Research paper (scientific journal)

Based on continuous GPS observation around the Itoigawa-Shizuoka Tectonic Line, central Japan, we found significant lateral heterogeneity in crustal deformation style along the tectonic line, which suggest complex behavior of the active fault. In addition, geodetic strain rate is found to have a good correspondence with the electronic registivity structure in the lower crust, implying lower crustal processes may control the stress accumulation process of the active faults.

A decade of GEONET: 1994-2003 - The continuous GPS observation in Japan and its impact on earthquake studies - Reviewed

Sagiya, T.

Earth Planets Space Vol. 56 page： xxix-xli 2004

Authorship：Lead author Language：English Publishing type：Research paper (scientific journal)

The dense continuous GPS network of Japan, now called GEONET, has been operated since 1994 by the Geographical Survey Institute. GEONET provides precise daily coordinates of all the stations, with which displacement rates and strain rates are calculated nationwide. Various characteristics of tectonic deformation in the Japanese Islands have been revealed. GEONET is also quite useful in earthquake studies, precisely detecting co-seismic, post-seismic, and inter-seismic deformation signals. These observations are utilized to infer physical processes at earthquake sources. Slow slip events on plate boundaries have been found from GPS data. Such slow events provide
an important constraint on the mechanism of faulting. On the other hand, there has been no success in detecting pre-seismic deformation. Lack of a precursory signal before the 2003 Tokachi-Oki (M8.0) earthquake has posed
a serious question to short-term earthquake prediction. GEONET enables a good linkage between monitoring and modeling studies, opening a possibility of practical data assimilation. For further contribution to earthquake studies,
it is necessary to continue GEONET with high traceability on the details in observation and analysis.

PAGEOPH Vol. 161 ( 11-12 ) page： 2601-2616 2004

Authorship：Lead author Language：English Publishing type：Research paper (scientific journal)

Using continuous GPS data, I estimated interplate coupling along the Sagami Trough subduction zone in the southern Kanto district. The shallow part of the plate boundary is considered to be fully locked and accumulating stress. In 1996, southeastern off the Boso Peninsula, anomalous slow deformation was detected and it is interpreted as a result of slow fault rupture on the plate boundary surface. Comparison of these results demonstrates that strongly locked patch and slow slip region show compensative distribution each other, supporting the basic concept of the asperity model.

Continuous GPS observation data in the Japan Islands are processed and the nationwide crustal deformation velocity field as well as the strain rate field are presented. In addition to the large strain region along the plate boundary, we identified an inland zone of large strain rate and named it Niigata-Kobe Tectonic Zone (NKTZ), which may have a significant implication for generation processes of inland large earthquakes.

We analyzed conventional triagulation as well as leveling data in the southwestern Japan to resolve the coseismic fault slip distribution of the 1944 Tonankai and the 1946 Nankaido earthquakes. Our analysis showed that onland geodetic data do not have resolving power for slips on the offshore segments. Estimated slip distribution indicates there are mainly three patches of large coseismic slip, southeast and south off shore the Kii Peninsula, and south of the Shikoku Island.
