IODP for Geohazard Mitigation
IODP for Geohazard mitigation: Estimation of rupture area and fault models for historical and pre-historical earthquakes by using submarine event deposit detected from ocean drilling survey Masanobu Shishikura and Yuichi Namegaya Geological Survey of Japan, AIST, 305-8576 Tsukuba, Japan (Corresponding: [email protected]) Abstract Constructing precise fault model of historical and pre-historical subduction zone earthquakes is important for evaluation and mitigation of seismic and tsunami hazards. Because parameters for constraining the model of further past events essentially lack due to limited records, it is necessary to obtain paleoseismological data by offshore piston coring and drilling. Detecting and identifying event deposit such as seismic turbidite, rupture extent can be constrained along the subduction zone. 1. Introduction Fault model is a foundation to evaluate future seismic phenomena such as strong ground motion, crustal movement, tsunami inundation and so on. To estimate fault models of historical or pre-historical earthquakes, we usually try to know their precise rupture area. Since there are no instrumental observation data for estimating them, it must be identified of the magnitude and distribution of crustal movement and tsunami by analyzing historical records and geomorphological and geological traces. In other words, these evidences are unique indicator, and can provide good parameters to estimate rupture area of such earthquakes. If the rupture area is located on coastal region, it is relatively easy to recognize crustal movement from relative sea level change (abrupt uplift and subsidence) that has been recorded in such as marine terrace. However, most of the rupture area of interplate earthquake along subduction zone is located off coast. -

Representations of Pleasure and Worship in Sankei Mandara Talia J
Mapping Sacred Spaces: Representations of Pleasure and Worship in Sankei mandara Talia J. Andrei Submitted in partial fulfillment of the Requirements for the degree of Doctor of Philosophy in the Graduate School of Arts and Sciences Columbia University 2016 © 2016 Talia J.Andrei All rights reserved Abstract Mapping Sacred Spaces: Representations of Pleasure and Worship in Sankei Mandara Talia J. Andrei This dissertation examines the historical and artistic circumstances behind the emergence in late medieval Japan of a short-lived genre of painting referred to as sankei mandara (pilgrimage mandalas). The paintings are large-scale topographical depictions of sacred sites and served as promotional material for temples and shrines in need of financial support to encourage pilgrimage, offering travelers worldly and spiritual benefits while inspiring them to donate liberally. Itinerant monks and nuns used the mandara in recitation performances (etoki) to lead audiences on virtual pilgrimages, decoding the pictorial clues and touting the benefits of the site shown. Addressing themselves to the newly risen commoner class following the collapse of the aristocratic order, sankei mandara depict commoners in the role of patron and pilgrim, the first instance of them being portrayed this way, alongside warriors and aristocrats as they make their way to the sites, enjoying the local delights, and worship on the sacred grounds. Together with the novel subject material, a new artistic language was created— schematic, colorful and bold. We begin by locating sankei mandara’s artistic roots and influences and then proceed to investigate the individual mandara devoted to three sacred sites: Mt. Fuji, Kiyomizudera and Ise Shrine (a sacred mountain, temple and shrine, respectively). -
Earthquake-Resistant Design for Architects Revised Edition to Whom This Report May Interest
Earthquake-resistant Design for Architects Revised edition To whom this report may interest, There are many earth quake prone countries in this world, not only Japan Therefore, at various occasions we were requested to explain our efforts and initiatives for reducing the risk of future earth quakes. After the Great Hanshin Earthquake, we had studied various methods to reduce the damages to ensure inhabitants lives, through collaborations of architects, structural engineers, building mechanical engineers and various specialists. Those considerations were realized in the book “Taishinkyohon” by the Japan Institute of Architects. The book was also revised after the Great East Japan Earthquake experiences. Owing to the language barriers, we are not able to explain easily our initiatives to outsiders. Therefore, we had tried to publish it in an English edition. Nevertheless through economic diculties, English editions had not been translated until now. In 2014, NPO called Japan Aseismic Safety Organization (JASO), decided to donate for the English translation, and furthermore their members donated for editing in English to form this report as well. A free report with internet download http://www.jaso.jp/ Since original Japanese book was published by publisher Shokokusha in Tokyo who still has the right to publish this book, we finally agreed that we would not sell commercially, but disperse only as a delivered free booklet with internet downloads. Therefore, anyone who likes to study is able to download from the HP of JASO who is holding their -

Approximately 45% of Japan’s tea is produced in Shizuoka. In this region, tea plants are often grown in hilly terrain. Therefore, due to this topographic setting, as well as other natural characteristics including geotechnical and geological conditions, tea plantation fields are occasionally subject to landslides. This paper investigates the relationship between the tea plantation fields and landslide prone areas in Shizuoka Prefecture. In this study, tea plantation fields are described from the engineering standpoint. Typical mechanisms of landslides that have occurred in the tea plantation fields are also studied. A series of investigations reveal that there are many common points between the tea plantation fields and the landslide prone areas in this region. Keywords: Landslides, Tea Plantation Fields, Primary Cause, Triggering Cause this paper investigates the relationship between the tea 1.

Numerical Tsunami Propagation of 1703 Kanto Earthquake
Numerical Tsunami Propagation of 1703 Kanto Earthquake Wu Yifei Supervisor: Kenji Satake Introduction Near Tokyo Bay, the 1703 Genroku Kanto Earthquake is known to generate a tsunami which hit the nearby coast. Considering the strength of the earthquake and the fault is quite close to Tokyo, we use numerical method to simulate the tsunami generated by the 1703 Genroku Kanto earthquake and see if there are any hazards when such a tsunami recurs. In our procedure, we first obtain ground deformation by Okada’s [1] program and then use the deformation as an initial condition to calculate the tsunami propagation. Properties of reverse fault Like the case of 1703 Genroku Kanto Earthquake, most big tsunamis that affect human being are caused by reverse fault. So we first examine the basic properties of reverse fault. Fig 1 and Fig 2 shows cross-section and map view Figure 1 Cross-section of deformation caused by reverse fault (W=15km, Slip=5m, Depth=0m) with different dips. Black line indicates the fault. The deformation is calculated by Okada’s program. Of the deformation caused by several reverse faults. Since in our procedure we consider vertical deformation as the cause of tsunami, we will just focus on that, or Uz. The most important thing we can gain is that for those reverse faults with dip not very large, we can observe uplift and subsidence. That makes the initial condition for tsunami propagation. Figure 2 Map view of the deformation caused by a reverse fault (L=85km W=55km Depth=5km Dip=30° Slip=6.7m) Yellow rectangle is the fault whose hanging wall is moving upward in the figure.
