“…This may explain the low amplitude of the DAS S wave reflection signal; however, the fact that we observe it implicitly suggests a high level of roughness between the basement and the sedimentary layer. Such roughness at the interface between the sedimentary layers and the Cretaceous bedrock is very well reported by active source reflection profiling data taken at the vicinity of the cable (Geological Survey of Japan, 2013; Kodaira et al, 2017;Minoura et al, 2015). Finally, we acknowledge that another possibility to explain the detection of these somewhat surprising phases could be attributed to incomplete reconstruction of the Green's functions by uneven noise sources distribution.…”

The Sanriku ocean‐bottom seismometer system uses an optical fiber cable to guarantee real‐time observations at the seafloor. A dark fiber connected to a Distributed Acoustic Sensing (DAS) interrogator converted the cable in an array of 19,000 seismic sensors. We use these measurements to constrain the velocity structure under a section of the cable. Our analysis relies on 24 hr of ambient seismic field recordings. We obtain a high‐resolution 2‐D shear‐wave velocity profile by inverting multimode dispersion curves extracted from frequency‐wave number analysis. We also produce a reflection image from autocorrelations of ambient seismic field, highlighting strong impedance contrasts at the interface between the sedimentary layers and the basement. In addition, earthquake wavefield analysis and modeling help to further constrain the sediment properties under the cable. Our results show for the first time that ocean‐bottom DAS can produce detailed images of the subsurface, opening new opportunities for cost‐effective ocean‐bottom imaging in the future.

The 2011 Great East Japan Earthquake (GEJE) has renewed the paradigm of disaster medicine. The Tohoku Journal of Experimental Medicine (TJEM) widened its scope to include the disaster science from the health perspectives. TJEM has been accumulating 76 articles related with "disaster" or "pandemic" out of which 69 were published after 2011. Tohoku University established the International Research Institute of Disaster Science (IRIDeS) that took initiative to impact the Sendai Framework for Disaster Risk Reduction 2015-2030 (Sendai Framework) to include health aspect. Sendai Framework provided the platform for collaboration of different sectors, including the terminology that defines the concept of disaster, risk, hazard & exposure, vulnerability and coping capacity. Disaster medicine covers the diverse causes and damages of disasters by various hazards in this globalized and rapidly changing world. TJEM articles range the physical and mental health damage after the GEJE and other disasters with approved ethical consideration of investigations from the view point of affected area, mechanisms of hazard to affect human health including the radiation, virus or hazardous materials, proposal of refinement of health system to cope with disasters such as mental health support, risk communication, disaster medical coordination and hospital business continuity plan and future perspectives with reconstruction including Tohoku Medical Megabank Project. TJEM scope on disaster medicine had been widened during the 10 years after GEJE and IRIDeS can be the bridging hub not only between the health sector and other sectors, but also between disaster medicine and other medical disciplines.

“…More than 1,100 years have passed since the Jogan tsunami … the possibility of a large tsunami striking the Sendai plain is high … A tsunami similar to the Jogan one would inundate the present coastal plain for about 2.5 to 3 km inland. (Minoura et al, 2001: 87) Minoura reiterated this warning (Minoura et al, 2015) in scientific publications and in the press. It was endorsed and repeated for years by senior seismologists at ministry-level meetings with TEPCO, operator of Fukushima Daiichi.…”
