With an estimated magnitude of 8.6 s y, it triggered a massive tsunami. The exact death toll from this event remains uncertain, but reports range from 5,000 to 41,000 casualties.https://www.ngdc.noaa.gov/hazel/view/hazards/tsunami/event-more-info/146 Global Historical Tsunami Database National Geophysical Data Center 1974 NOAA National Centers for Environmental Information 10.7289/V5PN93H7 Sahé Kaavje insightshub.in September 20, 2024 1498 Meiō earthquake https://insightshub.in/1498-meio-earthquake/ September 20, 2024 InsightsHub The tsunami, caused by the Meiō Nankaidō earthquake, washed away the building that housed the statue of the Great Buddha at Kōtoku-in in Kamakura, although the statue itself remained intact. Tectonic setting The southern coast of Honshū runs parallel to the Nankai Trough, where the Philippine Sea plate subducts beneath the Eurasian plate. Movement along this convergent boundary results in numerous earthquakes, some of which are of the megathrust type. The Nankai megathrust has five distinct segments (A–E) that can rupture independently.Ando M. 1975 Source mechanisms and tectonic significance of historical earthquakes along the nankai trough, Japan Tectonophysics 27 2 119–140 1975Tectp..27..119A 10.1016/0040-1951(75)90102-X Ishibashi K. 2004 Status of historical seismology in Japan http://www.earth-prints.org/bitstream/2122/763/1/02Ishibashi.pdf Annals of Geophysics 47 2/3 339–368 November 22, 2009 These segments have repeatedly ruptured, either singly or together, over the past 1,300 years.Sieh K.E. http://www.gps.caltech.edu/~sieh/pubs_docs/papers/P81b.pdf A Review of Geological Evidence for Recurrence Times of Large Earthquakes 1981 November 13, 2009 https://web.archive.org/web/20100604120819/http://www.gps.caltech.edu/~sieh/pubs_docs/papers/P81b.pdf June 4, 2010 dead Megathrust earthquakes along this fault tend to occur in pairs, with a relatively short time gap between them. In addition to two events in 1854, similar earthquakes occurred in 1944 and 1946. In each case, the northeastern segment ruptured before the southwestern segment.Kaneda Yoshiyuki 2007 Symposium on Underwater Technology and Workshop on Scientific Use of Submarine Cables and Related Technologies Kawaguchi Katsuyoshi Araki Eiichiro Matsumoto Hiroyuki Nakamura Takeshi Kamiya Shinichiro Hori Takane Baba Toshitaka 2007 978-1-4244-1207-5 299–300 Precise real-time observatory and simulating phenomena of earthquakes and tsunamis around the Nankai Trough – Towards the understanding of mega thrust earthquakes 10.1109/UT.2007.370806 45347574 In the 1498 event, the earthquake is believed to have ruptured segments C, D, and E, and possibly A and B. If both parts of the megathrust ruptured, the events were either simultaneous or close enough in time to be indistinguishable in historical records. Characteristics Severe shaking from this earthquake was recorded from the Bōsō Peninsula in the northeast to the Kii Peninsula in the southwest. A tsunami was recorded in Suruga Bay and at Kamakura, where it destroyed the building housing the statue of the Great Buddha at Kōtoku-in,Ishabashi K. https://books.google.com/books?id=UbkSAQAAIAAJ Earthquake prediction: an international review American Geophysical Union 1981 978-0-87590-403-0 Simpson D.W.

Evidence of severe shaking is also found in records of ground liquefaction in the Nankai area. Tsunami deposits attributed to this earthquake have been identified on the coastal plains around the Sagami Trough and the Izu Peninsula.Komatsubara J.

Lake Hamana became brackish after the tsunami broke through low-lying land between the lake and the Pacific Ocean (Enshū Nada), forming a channel to the sea that still exists today.Murata S. https://books.google.com/books?id=9j4DvH8XuUcC&pg=PA102 Tsunami: To Survive from Tsunami Imamura F.
