Research Abstract

The aim of this project is to reveal the feature of the crustal movement around the junction of the Kurile and the Northeastern arc, and to understand the difference of tectonics between Hokkaido and Northeastern Japan. In order to achieve the purpose, We established a regional GPS observation network for repeated campaign in Hokkaido, and performed the continuous measurements in Tohoku district. The correction of atmospheric path delay is also studied.
The regional GPS network of which baseline's length ranges from 100 to 300 km is established in Hokkaido. Some local network for research on prediction of earthquakes and volcanic eruption is also founded. Repeated campaigns of GPS measurements for the regional network are performed, and Short term repeatabilities are obtained less than 0.3ppm. The regional network detected the crustal deformation associated with the 1993 Hokkaido Nansei-Oki earthquake. Continuous measurements with on site recording at 2 new sites installed just after this event reveals post-seismic deformation.
The Continuous measurements carried out by using the network established in Tohoku district. It is confirmed that the continuous GPS array allows to detect variation of baseline with high temporary resolution and is effective to obtain the intraplate deformations.
A new correction method of atmospheric path delay based on the numerical weather prediction data have been developed. This study reveals that the data set of perceptible water vapor and temperature obtained by the GPS networks are useful to improve the accuracy of numerical prediction model. A new system combined the numerical prediction with the GPS meteorology through the estimation of atmospheric path delay.
