The source of this activity was around 12 km beneath an artificial lake. At the same time, activity on the Nagamachi-Rifu fault nearly ceased. More than 1550 micro-earthquakes were observed between 11 March 2011 and 1 August 2012, of which 63% exhibited similar waveforms and defined 64 multiplets. It appears that crustal extension of about 2 m during the Tohoku earthquake and additional extension of about 1 m during the following year changed the stress field in this region, thus generating micro-earthquakes and controlling their frequency. However, it has been presumed that crustal movement during the Tohoku earthquake did not affect the direction of principal stress, and that these events induced repeated quasi-static slips at asperities and the resultant micro-earthquakes. Keywords: acoustic emission swarm; 2011 Tohoku earthquake; repeating earthquake; multiplet; crustal movement 1. Introduction Acoustic emission (AE)/seismicity is important for evaluating the stability of geological structures; for instance, the delineation of fracture systems from AE activity in geothermal reservoirs is indispensable for thermal energy extraction [1]. The stability evaluation of fractures during hydraulic stimulation in geothermal reservoirs is necessary to avoid inducing large AE events, where the relationship between large AE events and the pore-pressure distribution in reservoirs is studied [2]. The stability of geological structures is also important from the viewpoint of disaster prevention. The dynamic behavior of geological structures has been studied by many seismologists who have examined repeating earthquakes and slow slip at seismic zones [3–5]. The 11 March 2011 Tohoku earthquake and its many aftershocks brought widespread destruction to eastern Japan [6–8]. This seismic activity occurred on both offshore and inland faults. Although thrust events dominated seismicity before and during the Tohoku earthquake, eastward movement of the shallow crust of the overriding tectonic plate caused extension that relaxed the subduction-related horizontal compressional stress locally, resulting in normal movement on some inland faults after the Tohoku earthquake [9]. Close observations of seismic activity are indispensable for the monitoring of the stability of geological structures. This paper describes a seismic swarm that occurred beneath an artificial lake near the plane of an active fault in Sendai city, Japan, after the Tohoku earthquake. It has long been known that changes in the water level of reservoirs can trigger substantial earthquakes, and it is shown that the seismic activity was sensitive to the small change of tectonic stress caused by the water level of the artificial lake.

It is composed of more than excitement in a haiku poem for Matsushima. 200 islands in Matsushima Bay and the islands just out into Matsushima and Matsushima Bay have long been the sea. Topographically Matsushima Bay suddenly breaks considered as a typical submerged coast, but they are inferred the gently concaved coastline from Sendai Bay to Ishinomaki to have been formed by a coastal mega-landslide in middle Bay. Matsushima and Matsushima Bay have been considered Holocene age from geological and topographical inferences. as a typical submerged coast, but they are inferred to have been formed by a coastal mega-landslide in middle Holocene age from geological and topographical evidences.

Introduction Mega-landslides due to volcanic activities and earthquakes have caused severe damage to the surrounding areas. Sector collapse of volcanoes is one of the most destructive landslides. Debris avalanche deposits from a sector collapse generally form strange topography punctuated by hundreds of small hills, ridges and closed depressions. The 1792 Mayuyama sector collapse of Unzen volcano in Kyushu, southern Japan, caused debris avalanche which flowed through ancient Shimabara City and entered the sea.

Come experience this healing journey, Miyagi Olle. At long last, a healing journey through magnificent landscapes and rich history < 3 Trails Version > Issue Date: First Edition September 2019 Miyagi Olle Trail, a Healing Journey Matsushima, its picturesque bay dotted with islands large and small, is the start of the journey to Miyagi Prefecture, a region rich with natural beauty. In the west is a range of mountains stretching from Mt. Zao to Mt. Funagata to Mt. Kurikoma. In the center, rice fields stretch out as far as the eye can see, with a beauty that changes from season to sea- son, and is ideal for experiencing traditional culture. The coastal area was badly damaged by tsunami caused by the 2011 Great East Japan Earthquake, but the coastal and mountain trails are being restored to their former beauty. Disaster became the opportunity which sparked the creation of the Miyagi Olle Trail, and with assistance from the Jeju Olle Foundation, in 2018 the Miyagi Olle Trail was created as a sister trail to those in Jeju (Korea), Kyushu and Mongolia. Miyagi Olle Trail has diverse routes, ranging from trails which travel by the endless stretch of the Pacific Ocean, to the natural richness of forested trails, to country roads with opportunities to meet local res- idents. While there are similarities to the Jeju Olle and Kyushu Olle, Miyagi has its own unique features. Olle trails are characterized by people coexisting with nature, and this is firmly embedded in Miyagi Olle as well.

All rights reserved. 0 Hitachi Solutions Donates GeoPDF Files to Aid Japan Quake Reconstruction Efforts Data to Facilitate Damage Verification in Disaster Areas through Comparison of Maps and Post-Disaster Satellite Imagery TOKYO, April 18, 2011 — Hitachi Solutions, Ltd. today announced that it will donate GeoPDF files to the Japanese government, in order to support reconstruction efforts following the recent March 11 Great Eastern Japan Earthquake and tsunami. Hitachi Solutions will provide the GeoPDF files, which deliver geographical information systems data in PDF format to facilitate viewing and adding of information, to the Cabinet Office for distribution to local disaster headquarters and municipal governments in areas affected by the disaster. The use of GeoPDF files will facilitate the verification of housing damage to greatly simplify the administration of Risai Shomeisho (Disaster Victim Certificates) issued to property owners. The files can also be effectively used for reconstruction planning. Hitachi Solutions is providing GeoPDF files that contain three layers of data: pre-disaster housing maps, estimated water submersion data, and post-disaster satellite imagery. Users can compare the layers to assess damage, and add data and photos to map points by using geographic coordinates. This process will greatly streamline the time it takes to verify damage, by enabling remote comparison of post-disaster satellite imagery with housing maps containing owner identification information.

    Tohoku J. Exper. Med., 1961, 73, 268-273 Studies on the Skin Test of Yato-Byo (Ohara's Disease, Tularemia in Japan) Fourth Report : Results of the Skin Test in Miyagi Prefecture By Toshio Kurokawa, Hisayuki Masuda, Kiyoaki Ichikawa, Masao Sato From the Medical Clinic of Prof. T. Kurokawa, Tohoku University, Sendai and Shoichiro Ohara From the Laboratory of Ohara Hospital, Fukushima (Received for publication, September 17, 1960) To diagnose yato-byo, both the immunologic and bacteriologic tests are generally used. They are the intracutaneous skin test, agglutination test and culture on some suitable media or inoculation of guinea pigs or mice with the infected materials. Of these methods the skin test is most popularly employed for the convenience of its procedure and its applicabililty for a mass examination. One of the authors already reported that the skin test was available for the early diagnosis of yato-byo in comparison with the agglutination test.') On the other hand, from the results of surveys by the skin test undertaken in Fukushima Prefecture, the infected areas with yato-byo were brought to light.2 1 In these surveys the positive cases of the skin test, which had no past history of manifest infection of yato-byo, were observed. However, their sera showed positive reaction for the agglutination test performed at the same time. They were thought to be the latent infection with yato-byo. We believe that the skin test is most suitable for the epidemiological study of yato-byo. We applied the skin test of yato-byo to mass examinations in several towns and villages in Miyagi Prefecture, the north eastern part of the main island of Japan, where yato-byo is frequently observed as reported by one of the authors.') The results and some epidemiological considerations are reported herein.
