Abstract We conducted seismic tomography for entire Japanese Islands including the Sea of Japan and the Pacific Ocean using arrival times from reflection survey as well as the routine seismic network. We successfully imaged the shallow zone along the

Abstract Cabled seafloor seismic and tsunami observation systems are ideal for marine geophysical monitoring because the data can be obtained in real time. We have developed a new compact seafloor‐cable seismic and tsunami observation system using

GPS differential positioning test on the Antarctic penetrator was made at the Aoyama Pasture, Ishikari-Tobetsu-machi, Hokkaido. The reference GPS receiving site was chosen in Hakodate, 200km southwest of the Aoyama Pasture, taking the planned operati

Recently, hydrothermal deposits below the seafloor are believed to be useful for human activity. Because the size of each deposit is much smaller than that of an offshore oil field, detailed exploration for the position and the estimated mass is need

Tomographic analysis of the seismic velocity structure beneath oceans has always been difficult because offshore events determined by onshore seismic networks have large uncertainties in depth. In order to use reliable event locations for our computa
