Recently, ocean bottom observation using seismometer and pressure gauge successes to document shallow slow earthquakes activity occurring in some subduction zones [e.g., Ito et al., 2013; Yamashita et al., 2015; Wallace et al., 2017]. Publish_year=2007. Along from the Nankai Trough to the Ryukyu Trench, shallow slow earthquake seismicity has been found by some previous studies. Earthquake and Tsunami Scenarios as Basic Information to Prepare Next Nankai Megathrust Earthquakes Takane Hori † Japan Agency for Marine-Earth Science and Technology 3173-25, Showa-machi, Kanazawa-ku, Yokohama 236-0001, Japan † Corresponding author Besides limited instrumental data of seismic waves and tsunami, distribution of ground shaking (seismic intensity) and tsunami heights (4–9 m) were documented. Nankai (Southern sea) Trough Earthquake The frequency of occurrence of the Nankai Trough Earthquake assumed by this map is 1/1,000years or lower, but if it occurs, Tsushima city will suffer serious damage. Among earthquakes, repeatedly rupturing along the Nankai trough, source of the M8 class Nankai earthquake covers segments from cape Shiono-misaki to cape Ashizuri-misaki, southwest Japan. Authors=NAKAMURA Fujio Journal/Book_names=Programme and Abstracts, the Seismological Society of Japan, Fall Meeting Likewise, the height of the 1960 Chile earthquake tsunami was about 1.5 m at the study site (The committee for field investigation of the Chilean tsunami of 1960, 1961 50 people / 3 - 5 m. 1983. The Showa-Nankai earthquake also caused coastal subsidence of at least 0.3 m or more in this area, such that groins built to stand above spring high tides were submerged to about 0.3 m depth at spring tides after the earthquake (Editing Committee of the History of Tokushima Prefecture 1963). To clarify the characteristics of tsunami duration on the south coast of Shikoku from Nankai trough earthquakes (which consists of four segments: Tokai, Tonankai, and two Nankai segments), numerical tsunami simulations were carried out. Considering that average KAWATA Kazuaki ! About 70 years have passed since the occurrence of these earthquakes, which is about half the average recurrence interval of a Nankai Trough Language_of_Text=JA. Earthquake Research Committee (1999):Seismic Activity in Japan Depth Depth Seismic activity of small to middle size earthquakes along Nankai Trough is NOT high . Tokachi-oki Earthquake / Approx. The Nankai Trough, where the Philippine sea plate is subducting beneath the Eurasian plate, is considered unique because it has a well-investigated recurrence interval and displays rupture zone segmentation of magnitude 8–class earthquakes ().Tsunami wave (2, 3) and seismic wave modeling studies have shown that the slip of the 1944 magnitude 8 Tonankai event propagated across all of … The last two Nankai Trough earthquakes occurred in 1944 (Showa Tonankai earth-quake) and 1946 (Showa Nankai earthquake), as indicated at the bottom of Figure 1. This map takes into account every possible situation in order to hypothesize the largest conceivable earthquake. Nihonkai Chubu Earthquake / Approx. The area remains seismically active, and future earthquakes are anticipated, with a high risk of a Nankai earthquake in the near future, which could be potentially very damaging. The magnitude was 8.6, and it triggered a large tsunami. Experts believe there is a 70% to 80% probability of a severe Nankai Trough earthquake within 30 years. In the early morning hours of December 21, 1946, a M 8.0 earthquake struck off the coast of southern Japan, triggering multiple tidal wives, causing major destruction and death in 15 prefectures, and other damage in a total of 25 prefectures. The Pacific coast of Shikoku district facing the Nankai Trough has suffered major tsunami each time due to a trench type earthquake repeated at 100 to 150 years cycle. 21 140 people / 5 - 6 m. 1968. Simulation of the Great Earthquakes along the Nankai Trough: An Attempt to Simulate Event History, Slip Areas of the Showa Tonankai / Nankai Earthquakes, Heterogeneous Slip Deficit Rate Distribution, and Long-term Slow Slips Fuyuki Hirose1, Kenji Maeda2, Kenichi Fujita1, and Akio Kobayashi1 100 people / More than 6 m. 1993. MURAKAMI Hitoshi. The Nankai Earthquake occurred at 08:00 local time of Japan off the coast of Nankaido, Japan on September 20, 1498. Earthquake . 2011 ). The last event was the 1946 Nankai earthquake (the Showa Nankai earthquake). 1904～1995 . Tōkai, Tōnankai and Nankai earthquakes occurred at the same time with magnitude 8.4–8.6. Plate-boundary earthquakes of magnitude 8 or greater along the Suruga–Nankai Trough subduction zone have repeated at intervals of 90–150 years, but with widely varying magnitudes and rupture areas. More The Earthquake Research Committee announced in May 2013 that the chance of a quake of magnitude 8 or more happening in the Nankai Trough within 30 years was between 60 and 70 percent.
