<p>The geometry/angle of the deeper extension of active fault is one of the fundamental information to evaluate the magnitude of inland earthquake associated with active faulting. The information is mainly revealed by geophysical exploration that is executed across the active fault. Although the geophysical explorations were scarcely applied for strike-slip fault in Japan, we discuss the applicability of several geophysical explorations, seismic reflection and refraction survey, CSAMT (controlled source audio-magnetotelluric) survey and gravity survey for strike-slip fault in this study. The study area is located in northwest area in Kinki region in Japan, and Go-mura fault zone and Yamada fault zone are distributed in a granite area (Miyazu granite). In the seismic reflection profile, discontinuity and inflection of reflector shows the deeper geometry of active fault in 200-300 m below the surface of the ground. In some profile, discordance between subsurface structure and slip direction of the active fault were shown. Hence, the comparison between seismic reflection profile and other geophysical explorations is important in the interpretation of subsurface geometry of the active fault. Although, the seismic refraction image cannot define the strict angle of the active fault in principle, the image well indicates the low-velocity layer crushed by the strike-slip faulting. In the CSAMT survey, low-specific resistance area extended in depth clearly shows the geometry and angle of deeper part of active fault. In some image, pseudo-specific resistance can be seen in some CSAMT image, comparison to other information of geophysical survey is necessary for interpretation. Because the vertical displacement is not dominant in strike-slip faulting, the gravity survey across the strike-slip fault is generally insufficient method to detect the fault. Dense spacing of gravity stations and precise measurement allow sensing the Bouguer gravity anomaly associated with strike-slip faulting.</p>

Triangulation scale error caused by the 1894 Shonai earthquake: a possible cause of erroneous interpretation of seismic potential along the Japan Trench

Horizontal crustal strain in the Tohoku area during the twentieth century based on triangulation showed N-S extension and E-W contraction was not significant. This feature was one of the reasons why the 2011 Tohoku-oki earthquake was unexpected for many scientists. The first triangulation conducted in the late nineteenth century used a length scale defined by baseline surveys, direct measurements of short (2-10 km) baselines with steel rods. The Shionohara baseline in the Yamagata prefecture was measured in May-July 1894 and the 1894 Shonai (M7.0) earthquake occurred in its western neighbor 3 months after the measurement. The earthquake possibly elongated the baseline by as large as 5 cm or 10 ppm. However, the original length measured before the earthquake was used for the network adjustment of the entire triangulation network, causing extensive underestimation of the length scale of the network as large as 5-10 ppm in northeast Japan. The scale error effect was comparable to tectonic deformation signal over 100 years. The baseline length was re-surveyed in 2012, 1 year after the Tohoku-oki earthquake, and the result is consistent with the hypothesis of scale bias considering interseismic deformation.

Seismic and inter-seismic ground surface deformations of the Murono mud volcano (central Japan): a laser scanning approach

HAYAKAWA Yuichi S., KUSUMOTO Shigekazu, MATTA Nobuhisa

Progress in Earth and Planetary Science (Web) 4 ( Feb ) 3 2017

Language：English Publisher：SPRINGER

A small mud volcano in Murono, Niigata Prefecture, north-central Japan, shows active ground surface displacements, not only when large earthquakes occur in the region but also during quiescent periods between earthquake events. The site recently underwent abrupt deformations due to strong regional earthquakes in 2004, 2007, 2011, and 2014, while gradual surface deformations were reported during quiescent periods between the earthquakes. To detect the spatial distribution of the changes in the mud volcano's ground surface elevation, we carried out multi-temporal terrestrial laser scanning. Point cloud datasets were registered at different times by minimizing the distance between the closest points in different clouds for stable ground features, which revealed centimeter-to decimeter-scale deformations around the domain of the conspicuous uplift. The spatial distribution of the deformation triggered by the earthquakes, including both central uplift and peripheral subsidence, exhibits an elliptical pattern, on which open crack fractures, associated with the earthquake-triggered uplift, were formed. The displacement and stress fields for the earthquakes were modeled numerically, and anomalously high pressure and/or weakening of the surficial materials was expected for the formation of fractures in the local domain. In contrast, continuous uplift was observed during the inter-seismic quiescent periods, the domain of which seems to have changed after the strong earthquake in 2014. In the coming years, further measurements will be necessary to unravel the physical subsurface mechanics of the mud volcano.
