sanriku japan tsunami 1896
1a shows that the strong ground shaking was recorded to the south of the epicenter, where large (> 10 m) slip occurred at deeper (> 7 km) subfaults. Isl Arc 6:261–266, Tappin DR, Grilli ST, Harris JC, Geller RJ, Masterlark T, Kirby JT, Shi F, Ma G, Thingbaijam KKS, Mai PM (2014) Did a submarine landslide contribute to the 2011 Tohoku tsunami? The computed tsunami heights are similar to the observed heights on the northern Sanriku coast, but larger than those on the southern coast (Figs. Two factors may contribute to this difference: distance from the source to the coast and the seafloor displacement due to faulting at different depths. It describes as follows. (top) Slip distribution on subfaults (color bar scale in the right) and computed maximum tsunami height (color bar scale in the left) for 6 models. The Sanriku Coastal Area, a tsunami-prone region located in the northern part of the main island of Japan, survived catastrophic tsunamis in 1896, 1933, and 1960. Geophys Res Lett. 2f). It was thus attributed as submarine landslide by Tappin et al. 1c, d). 2011; Satake et al. Although the depths of largest slip of the 1896 and 2011 earthquakes were different, the frictional properties on these shallowest subfaults may be similar. The Great Meiji Sanriku Tsunami: Pictograph: Date: June 15, 1896: Place: Sanriku coast of the Tohoku region, Japan: Location: along the Sanriku coast: Overview: After a strong earthquake with a magnitude of 8.5 occurred 150 km off the Sanriku coast, a huge tsunami struck the coast of Sanriku. Sanriku, Japan The tsunami to hit Sanriku, Japan on June 15th, 1896 was caused by an earthquake of a magnitude 7.6. Geophys Res Lett 23:861–864, Tanioka Y, Satake K (1996b) Fault parameters of the 1896 Sanriku tsunami earthquake estimated from tsunami numerical modeling. https://doi.org/10.1785/0120120122, Sella GF, Dixon TH, Mao AL (2002) REVEL: a model for recent plate velocities from space geodesy. 1d), probably due to the different sizes of tsunami source. On March 11, 2011 at 14:46, the most powerful earthquake ever recorded in Japan occurred 70 kilometers off the Pacific coast of the Tohoku Region. 2c) shows large (20 m) slip on subfault 1B, deeper and second northernmost subfault. 1896 many villages along the coast of Sanriku were celebrating the return of the soldiers from the war against China, when an earthquake of magnitude 8.5 occurred nearly 145 kilometers offshore of Honshu. No written records of large tsunamis are available before the 1896 event. Kenji Satake. (2014). During a Shinto festival on June 15, 1896, an earthquake off the coast of Sanriku, Japan estimated to be 8.5 magnitude on the Richer Scale, caused about five minutes of slow shaking. Blue and green circles with bars are computed heights on 6″ grid. Science 332:1426–1429. The damage was particularly severe because the tsunamis coincided with h… Pure Appl Geophys 154:467–483, Satake K, Nishimura Y, Putra PS, Gusman AR, Sunendar H, Fujii Y, Tanioka Y, Latief H, Yulianto E (2013a) Tsunami source of the 2010 Mentawai, Indonesia earthquake inferred from tsunami field survey and waveform modeling. The effects of a 20° dipping fault along the top of the subducting plate was found to match both the observed seismic response and tsunami, but required a displacement of 10.4 m. The displacement was reduced to a more reasonable value after the extra uplift caused by the deformation of sediments in the wedge and a shallower fault dip of 10° was considered. However, 35 minutes later the first tsunami wave struck the coast, followed by a second a few minutes later. , Wave heights of up to 9 meters (30 ft) were also measured in Hawaii. Geophys J Int 159:129–145.
