The tsunami heights on the Sanriku coast are similar to the above final model (K = 1.32), while the computed tsunami waveforms are slightly different; the periods of the first wave become shorter and the amplitude at Ayukawa is slightly larger. Tsunami waveforms computed at Miyako from the 2011 model (8 subfaults) and the 1896 final model. Sanriku, Japan The tsunami to hit Sanriku, Japan on June 15th, 1896 was caused by an earthquake of a magnitude 7.6. (2014). Tsunami heights on the Sanriku coast reported by (a) Iki (1897) and (b) Matsuo (1933) are shown by black circles. Comparison of the 1896 and 2011 tsunami waveforms indicates that both periods and amplitudes of the 2011 waveforms are larger than those of the 1896 tsunami (Fig. Although the 1896 tsunami heights were measured 37 years after the occurrence based on the eyewitness accounts, the survey points were plotted on 1:50,000 maps and provided valuable information. The 8.5 magnitude earthquake occurred at 19:32 (local time) on June 15, 1896, approximately 166 kilometres (103 mi) off the coast of Iwate Prefecture, Honshu.. On the evening of June 15, 1896, communities along the Sanriku coast in northern Japan were celebrating a Shinto holiday and the return of soldiers from the First Sino-Japanese War. https://doi.org/10.1111/j.1365-246X.2004.02350.x, Tanioka Y, Satake K (1996a) Tsunami generation by horizontal displacement of ocean bottom. c Tsunami heights on the Sanriku coast from the 1896 Sanriku tsunami (blue symbols with different shapes for the data source) and the 2011 Tohoku earthquake (red symbols with different shapes for runup and inundation heights) from Tsuji et al.

For the Sanriku coast, additional computations including inundation on land with the finest grid size of 75 m are also made, and the computed tsunami heights are compared with the 143 heights reported by Iki (1897) and the 260 heights reported by Matsuo (1933) (Fig. We need to formulate future strategies for post-disaster recovery policy and planning based on the lessons of past disasters. 5). Pure Appl Geophys 144:455–470, Satake K, Tanioka Y (1999) Sources of tsunami and tsunamigenic earthquakes in subduction zones. The water depth at these subfaults are also different: the water is deeper for the shallower subfaults near the trench axis. Kamaishi has been periodically hit by tsunami over the centuries, including the ones that struck the Sanriku Coast in 1896 and 1928.

During the 1896 Sanriku earthquake, the large (20 m) slip occurred on subfaults (1B and 1C: Table 1) at a depth of 3.5–7 km. The 1896 Sanriku earthquake was one of the most destructive seismic events in Japanese history. Terms and Conditions, Earthquake and giant tsunami at the coast of Sanriku (Japan), which led to 25 000 victims.The quake (M=8,5) was followed by a tsunami reaching the height of 38,2 m. It took 10 000 villages at the coast. Bull Seismol Soc Am 84:415–425, Aida I (1978) Reliability of a tsunami source model derived from fault parameters. An almost identical event occurred in the same location in 1896, causing the deaths of more than 26,000 people. This model explains both tsunami heights on the Sanriku coast and the recorded tsunami waveforms, and yields the smallest κ, hence considered as the best model of the 1896 Sanriku earthquake.  As was their normal practise each evening, the local fishing fleets were all at sea when the tsunamis struck. https://doi.org/10.1007/s00024-014-0779-x, Unohana M, Ota T (1988) Disaster records of Meiji Sanriku tsunami by Soshin Yamana. The delayed rupture along the northern Japan Trench during the 2011 Tohoku earthquake was estimated by tsunami data (Satake et al. This is contrary to the 2011 Tohoku earthquake model, which had large slips at shallowest subfaults. (1997) further proposed that the 1896 Sanriku ‘tsunami earthquake’ occurred in a region where the ocean bottom topography is rough, characterized by well-developed horst and graben structures. The often-quoted maximum height of 38 m at Shirahama from the 1896 Sanriku tsunami was based on his report. Een van de getroffen gebieden in 1896 2012), and tsunami waveforms (Fujii et al.

The 8.5 magnitude earthquake occurred at 19:32 (local time) on June 15, 1896, approximately 166 kilometres (103 mi) off the coast of Iwate Prefecture, Honshu.It resulted in two tsunamis which destroyed about 9,000 homes and caused at least 22,000 deaths. http://www.dpbolvw.net/click-5028330-10426267 (2013b), but only the spatial slip distribution is estimated. The strike, dip, and slip angles are 193°, 8°, and 81°, respectively. Blue and green circles with bars are computed heights on 6″ grid. Part of The origin time: 19 h 32 m (local time), the epicenter: 144°E, 39.5°N, and magnitude: M = 6.8 were estimated from Japanese seismological data (Utsu 1979). The 1896 tsunami was instrumentally recorded on three tide gage stations at regional distances in Japan: Hanasaki (440 km from the epicenter), Ayukawa (250 km), and Choshi (500 km) (Fig. In the present study, the local tsunami amplification observed in Ryori Bay, located on the Sanriku coast of Japan, was investigated using numerical simulations. Zisin (J Seis. The computed tsunami heights are similar to the observed heights on the northern Sanriku coast, but larger than those on the southern coast (Figs. 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. The Sanriku region of Japan The 36 bays of this irregular coastline tend to amplify the destructiveness of tsunami waves which reach the shores of Sanriku,  as demonstrated in the damage caused by the 2011 Tōhoku earthquake and tsunami . 2b). https://doi.org/10.1029/2011JB009133, Matsuo H (1933) Report on the survey of the 1933 Sanriku tsunami. We also compare the tsunami source models, or obtained slip distributions, of the 1896 and 2011 earthquakes, and discuss why the 2011 earthquake was not a ‘tsunami earthquake.’. It resulted in two tsunamis which destroyed about 9,000 homes and caused at least 22,000 deaths After a small earthquake, there was little concern because it was so weak and many small tremors had also been felt in the previous few months. The 1896 Sanriku earthquake was one of the most devastating tsunami earthquakes, which generated an anomalously larger tsunami than expected from its seismic waves. Shaking from the 1896 event was not widely felt but the tsunami destroyed nearly 9,000 homes and claimed more than 22,000 lives, making this one of the most damaging earthquakes in Japan’s history. We also consider the effects of horizontal displacement on a steep bathymetric slope (Tanioka and Satake 1996a).

The non-linear shallow-water equations including advection and bottom friction terms and the equation of continuity on the spherical coordinate system are numerically solved (Satake 1995). Red curves are observed waveforms and blue curves are computed ones. The largest heights of 55 m were reported at two locations. The 1896 Sanriku tsunami earthquake that occurred along the Japan trench was one of the most anomalous earthquakes; the ground shaking was relatively weak, but the following tsunamis were devastating. It is estimated that 27,000 people lost their lives. The slip ratio (2011/1896) is smaller than one in the deeper (3.5–7 km) subfaults except for the southern one (1D), while the ratio ranges 1.9–13 on the shallowest subfaults (Table 1). The In this study, we re-estimate the slip distribution, particularly in depth direction, of the 1896 Sanriku ‘tsunami earthquake’ based on both tsunami heights on the Sanriku coast and the tsunami waveforms recorded on three tide gage stations at regional distance in Japan. We adopt the finite-difference method with the grid interval of 6″ (140 to 190 m). More recently, Lay et al. 1c). We first adopt the northeastern eight subfaults of the 2011 Tohoku earthquake tsunami source model (Satake et al. However, additional tests indicate that the water depth difference makes an insignificant effect for the tsunami heights on the Sanriku coast. 5 Tsunami memorial stone: Such as stone monuments, can be found in many areas along the Sanriku coast. He measured tsunami heights based on various kinds of traces and eyewitness accounts, and assigned different reliabilities depending on the kind of data. w = 8.1. 1b). Juni 1896 ( Meiji 29) vor der Küste Japans um etwa 19:32 Ortszeit. In this study, we adopt the reported tsunami heights by Iki (1897) and Matsuo (1933) and compare them with the calculated heights. Abe K (1979) Size of great earthquakes of 1873–1974 inferred from tsunami data. It was immediately after Meiji Tsunami 1896 when Soshin Yamana, an entrepreneur from (1) On June 15, 1896, one of the most destructive seismic events in Japanese history occurred when an 8.5 magnitude earthquake happened and triggered 2 tsunamis, their waves reaching up to 125 feet. It occurred along the Japan Trench in the northern tsunami source area of the 2011 Tohoku earthquake where a delayed tsunami generation has been proposed.

Tesla Tsunami. statement and It resulted in two tsunamis which destroyed about 9,000 homes and caused at least 22,000 deaths. Preventive coastal measures were not implemented until after another tsunami struck in 1933. Iki (1897) made a survey in June and July of 1896 along the Sanriku coast. The trench forms part of the convergent boundary between the Pacific and Eurasian plates. At about 19 h 50 m, the sea began to recede. 1b, Honda et al. Konkrete Beispiele für Tsunamis an der Sanriku-Küste sind das Jōgan-Sanriku-Erdbeben 869, das Keichō-Sanriku-Erdbeben 1611, das Meiji-Sanriku-Erdbeben 1896 mit insgesamt 22.000 Toten und einer maximalen Auflaufhöhe von 38 m in Ryōri -Shirahama (heute: Ōfunato, Präfektur Iwate), das Shōwa-Sanriku-Erdbeben 1933 mit 3000 Toten und einer maximalen Auflaufhöhe von 29 m in Ryōri … The computed tsunami heights on the southern Sanriku coast become smaller and similar to the observed (Figs. https://doi.org/10.1046/j.1365-246x.2000.00205.x, https://doi.org/10.1007/s00024-012-0536-y, https://doi.org/10.1111/j.1365-246X.2004.02350.x, https://doi.org/10.1016/j.margeo.2014.09.043, https://doi.org/10.1007/s00024-014-0779-x, http://creativecommons.org/licenses/by/4.0/, https://doi.org/10.1186/s40562-017-0099-y. s 8.5). Note that the scale for horizontal axis is location numbers (Additional file 1: Table S1, Additional file 2: Table S2), not distance. 2011), inland and submarine geodetic data (Iinuma et al. Why was the 1896 event a ‘tsunami earthquake’ while the 2011 earthquake was not? However, the computed tsunami waveforms at regional distances are much larger than the recorded ones, particularly at Hanasaki and Ayukawa (Fig. The tsunami was also observed across the Pacific. (bottom) Tsunami waveforms at three tide gage stations at regional distances. w 9.0 Tohoku-Oki earthquake. "On June 15, 1896, nearly 22,000 Japanese lost their lives due to the most devastating tsunami in Japanese history. In addition, the tsunami arrival times were measured relative to the earthquake. The inversion method is similar to Satake et al. Previous studies indicate that the earthquake occurred beneath the accretionary wedge near the trench axis. , The epicenter lies just to the west of the Japan Trench, the surface expression of the west-dipping subduction zone. YF made tsunami simulation and inversion using the coarse grid. Mar Geol 357:344–361. The tsunami heights on the Sanriku coast from this model are smaller (K = 1.63), while the tsunami waveforms at regional distances are similar to those from the previous uniform-slip model at 3.5–7 km depth. 35 minutes later, the tsunami was reported at Shirahama that reached as high as 125 feet (38.2 m), causing damage to more than 11,000 homes and killing some 22,000 people.
