Earthquake swarm around Nakagawa town, northern Hokkaido in 2012
Ichiyanagi, M; H. Takahashi; T. Yamaguchi; R. Azuma; T. Yamada; M. Ohzono; A. Shinjo; M. Kasahara; Y. Tanioka, An earthquake swarm begun at 15 July 2012 in Nakagawa town of northern Hokkaido. The largest earthquake with MJMA4.3 occurred on 16 July 2012. We carried out temporal seismic observation with seven stations from 18 July 2012 to the last October 2012. Hypocenters were calculated using the Double-Difference hypocenter determination procedure with a local one dimensional P-wave velocity structure. Precise hypocenter data indicated that epicenters were distributed in very narrow area of 2 km×2 km with shallow depth from 4 km to 7 km. Earthquakes after middle of August occurred only in southern part of the region and depth had got shallower with time. Hypocenters indicated no clear alignment in consistent with any nodal planes of major earthquakes. An independent hypocenter cluster with shallower than 2 km was observed above the main activity area. A slow slip event (SSE) with Mw 5.4 coincidentally detected by GNSS crustal deformation data during the swarm. This swarm was situated at the southeastern end of the fault of SSE. This fact suggested that seismic swarm might triggered SSE or was induced by SSE., 北海道大学大学院理学研究院

Seismic Activity Associated with the 2010 M4.6 Sapporo Earthquake in central Ishikari region, Hokkaido
一柳昌義; 山口照寛; 高田真秀; 東龍介; 黒井和典; 山田卓司; 高橋浩晃; 前田宜浩, On December 2, 2010, MJMA4.6 shallow felt earthquake occurred beneath southeastern part of Sapporo city. Three temporal seismic stations were installed near epicentral area. Reliable hypocenter data estimated by double difference procedure with local seismic velocity structure indicated clear southeastern-dipping distribution. Fault plane from focal mechanism estimated from P-wave polarization well agreed with this hypocenter distribution. Geometry of hypocenter distribution was also well consistent with an anticline structure and possible buried active fault estimated for earthquake disaster damage assumption by local government. Recalculation of hypocenters of the 1985, 1990, and 2010 felt earthquakes under equal condition implied that epicentral locations of these three events were approximately same. These facts implied possible stress concentration in epicentral region., 北海道大学大学院理学研究院

Development of an Observation System for Ocean Bottom Crustal Deformation Using an Acoustic Ranging-GPS Link
TADOKORO Keiichi; ANDO Masataka; SATO Kazutoshi; YAMADA Takuji; OKUDA Takashi; KATAO Hiroshi; KISHIMOTO Kiyoyuki, We have developed an observation system for ocean bottom crustal deformation using an acoustic ranging-GPS link. A seafloor-positioning test at Suruga Bay revealed that our system can obtain the horizontal location of a sea-bottom station within 5 cm (95 % confidence interval) using accurate GPS positioning data. GPS positioning error is a major source of error in our whole system. We carried out experiments on kinematic GPS positioning with a long base line and a moving antenna to investigate its accuracy. The results of the experiments suggest that data with PDOP (Position Dilution of Precision) of 2 or less can reduce the GPS positioning error to 7 cm. The network of the observation system for ocean bottom crustal deformation may lead to advances in tectonic studies along subduction zones and contribute to predictions of interplate large earthquakes in the future., Tokyo Geographical Society
