AbstractDespite recent observations of slow earthquakes along the Nankai subduction zone, none have been reported in the central Nankai Trough between the Kii Channel and Cape Shionomisaki. A study by the Japan Society of Civil Engineers in 2018 estimated that the long-term damage from the earthquake could result in 1,240 trillion yen in economic losses over a 20-year period. Keywords: core-to-core collaborative research, disaster mitigation, hazard estimation, risk evaluation, Nankai Trough earthquake. In southwest Japan, large earthquakes around M 8 have repeatedly occurred in the Nankai Trough (hereafter referred to as Nankai Trough earthquakes) at intervals of ~100–200 years (Ando, 1975). Published online by Cambridge University Press: 14 February 2020; Abstract. In 2012, the government released its estimates on the highest tsunami in case of a Nankai Trough earthquake. In addition, we calculated the tsunami propagation that would be caused by the Nankai Trough earthquake, taking into account the largest class of earthquakes excluded by ERC (see also Hirata et al., this meeting). Figure 1 illustrates the location of the Nankai Trough together with the epicenter of the 2011 earthquake and the resulting tsunami areas. The Japanese government estimates that a major earthquake on the Nankai Trough would cause 169.5 trillion yen in direct damage and 50.8 trillion yen in economic losses for the following year. "If the Nankai Trough quake happens, 320,000 people are expected to die if no measures are taken," Professor Matsuo said. Four phases and seven key tasks “Life-saving” phase Task 1 Disseminate timely information, and fully support evacuation from mega tsunami’s landfall in short timeframe. The research program titled “Earthquake and Volcano Hazards Observation and Research Program” was started in fiscal year (FY) 2014 as a new five-year project authorized and funded by the Council for Science and Technology of … To be ready for a national crisis should the Nankai Trough Mega Earthquake occur, we are making every effort to promote various operations.

First, the recurrence intervals of earthquakes in the Tōkai and Nankai regions appears to be different before and after the 1361 CE earthquake . Prehosp Disaster Med. The observation systems There are over 15 observation sites along the Nankai Trough: six established before the 2011 Tohoku-oki earthquake, and others deployed subsequently in order to produce a complete picture of the SDR distribution. Share 0; Tweet list; Print; The Asahi Shimbun. Some questions remain about the recurrence pattern of Nankai Trough earthquakes. Above 45°C, concentrations of vegetative cells drop two orders of magnitude and endospores become more than 6000 times more abundant than vegetative cells. According … The adjacent locked area along the Nankai trough subduction zone is a well-known seismic gap and the 2018–2019 SSE changed the stress state in favor of the occurrence of nearby subduction earthquakes. It targeted 108 municipal education boards -- 72 cities in 13 prefectures in the central government-designated areas under increased measures against the Nankai Trough earthquake … The AD 1498 submarine … In this paper, we report on … Journal of Geophysical Research: Solid Earth , 125, e2019JB019047. As there have been no reports of such earthquake-induced landslides during historical megathrust earthquakes along the Nankai–Suruga Trough (e.g., Garrett et al., 2016) and other subduction zones, it would appear that it is extremely rare for an M8 earthquake in the trough to cause deformation of coastal landforms by the generation of submarine landslides. The two best known faults in Japan are the Itoigawa-Shizuoka Tectonic Line (ISTL) which cuts across Honshu north to south just west of Tokyo and the Median Tectonic Line (MTL) which is an east-west trending strike-slip fault that parallels the Nankai Trough from the Kii Peninsula into the heart of Kyushu. This is the last in a series of investigative reports from the Chunichi Shimbun about how figures for the probability of a Nankai Trough earthquake were manipulated for a … The Nankai Trough and Cascadia are very similar subduction zones in that they have large accretionary prisms and produce large earthquakes and tsunami. Thank you for your … But it’s always a good idea to be prepared for natural disasters when living in Japan, no matter where you are or how it smells on any given day. 2020;35(2):160–164. The committee calculated the possibility of tsunami as of Jan. 1, 2020, with reference to magnitude-8 or 9-class earthquakes along the Nankai Trough that had happened once in about 100 or 200 years. The Nankai Trough is a submarine trench on the Pacific side of the Japanese archipelago stretching from the eastern part of the main island of Honshu to waters east of … He is working on a Japan Society for the Promotion of Science-funded project entitled 'Urgency Evaluation of the Nankai Great Earthquake and Tsunami by Scientific Ocean Drilling' (lead by Gaku Kimura) that is seeking to estimate the earthquake likelihood of a severe Nankai Trough earthquake.

Details of the Nankai Trough Mega Earthquake Operation Plan. Methane is biologically produced and oxidized until sediments reach 80° to 85°C. Q: Yasir Javed, New Zealand If we can get data on the patterns of small tremors before big devastating earthquake from the past, why can't we use such patterns to predict the future devastating earthquake by such tremor patterns currently? Elizabeth Sherrill, a doctoral student at Indiana University, presented her work on the Nankai trough, which has produced two major megathrust earthquakes in the recent past — the 1944 magnitude-8.1 Tonankai earthquake and the 1946 magnitude-8.4 Nankai event. A biennial survey by Shizuoka Prefecture showed in 2017 that the percentage of residents “very interested” in the Nankai Trough or Tokai earthquakes stood … Nankai Trough earthquake risk map. The regular and slow interplate earthquakes were separately distributed, with these distributions reflecting the heterogeneous distribution of effective strengths on the plate boundary. The Japanese government believes that the number of casualties would be huge. Nankai Trough Earthquake Evaluation Study Group "No particular changes observed" October 7, 19:10. 1 shows the spatial distribution of regular earthquakes with moment magnitudes (M w) of 4.3–6.5 that occurred from April 2004 to August 2019, as listed in … The 1707 CE Hōei and 887 CE Nin-na earthquakes were full-length ruptures of both the Tōkai and Nankai fault segments (Fujiwara et al., 2020).
