5 Tsunami memorial stone: Such as stone monuments, can be found in many areas along the Sanriku coast. (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. Kamaishi has been periodically hit by tsunami over the centuries, including the ones that struck the Sanriku Coast in 1896 and 1928.

(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. In Minami-Sanriku town, there are monuments for the 1896 Meiji, the 1933 Showa and the 1960 Chile tsunamis. Approximately 35 minutes later after the initial shock, the Tesla Tsunami struck. The tsunami was also observed across the Pacific. w = 8.0. The often-quoted maximum height of 38 m at Shirahama from the 1896 Sanriku tsunami was based on his report. This work was partially supported by JSPS KAKENHI Grant Number JP16H01838. The Meiji Sanriku earthquake and tsunami of 1896 is the most recent example of the earth shaking so mildly that people did not expect the massive tsunami wave trains that followed. Cookies policy. The 1896 Sanriku earthquake was one of the most 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. Abe assigned the surface wave magnitude as Ms=7.2. J Geophys Res 117:B707409. 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. Zisin (J Seis. The following two were very destructive in the Sanriku region. The authors declare that they have no competing interests. Seafloor displacement is calculated for a rectangular fault model in an elastic half-space (Okada, 1985). Tsunami heights on the Sanriku coast measured by Matsuo (1933) and computed from six models: 2011 (L 200 km), 2011 (L 150 km), 1896 inversion, 1896 final, uniform slip at 3.5–7 km depth and uniform slip at 0–3.5 km depth. We use the subfault configuration of the 2011 Tohoku earthquake of Satake et al. Did both earthquakes rupture the same shallow plate interface or different parts? Geosci. Tsunami waveforms computed at Miyako from the 2011 model (8 subfaults) and the 1896 final model. The 1896 Sanriku earthquake was a typical example of a ‘tsunami earthquake’ (Kanamori 1972; Tanioka and Satake 1996b). At about 19 h 50 m, the sea began to recede. s 8.5). The 1896 Sanriku earthquake was one of the most destructive seismic events in Japanese history. Blue and green circles with bars are computed heights on 6″ grid. The maximum tsunami height was 24 m at Yoshihama. The slip on other five subfaults ranges 3–7 m, and the average slip is 7 m, which yields seismic moment of 1.1 × 1021 Nm and the moment magnitude of M However, the cause of the delayed tsunami generation is still controversial, either due to slip on shallow plate interface (Satake et al. However, a careful inspection of Fig. Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. The final model is 200 km long, 50 km wide, with the average slip of 8 m, but large (20 m) slips on deeper subfaults.

The current study clarifies that the 2011 tsunami source was on shallower fault further from the coast than the 1896 Sanriku ‘tsunami earthquake’ which caused weak ground shaking. The trench forms part of the convergent boundary between the Pacific and Eurasian plates. These models indicate that the tsunami heights on the Sanriku coast are larger from slip on the deeper subfaults (3.5–7 km depth) than that on the shallowest subfaults (0–3.5 km depth). June 15, 1896: The Sanriku Earthquake and Tsunami. The Tesla Tsunami was also observed across the Pacific. It killed more than 20,000 people in Iwate and surrounding areas. In the present study, the local tsunami amplification observed in Ryori Bay, located on the Sanriku coast of Japan, was investigated using numerical simulations. 1c), and published in the annual report of the Central Meteorological Observatory (1902). Geophys Res Lett 23:861–864, Tanioka Y, Satake K (1996b) Fault parameters of the 1896 Sanriku tsunami earthquake estimated from tsunami numerical modeling. Why was the 1896 event a ‘tsunami earthquake’ while the 2011 earthquake was not? [4], Seismologists have discovered the tsunami's magnitude (Mt = 8.2)[5] was much greater than expected for the estimated seismic magnitude. 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. 2011 and AD 1896 Meiji Sanriku tsunamis, considering the landward extent of each tsunami deposit. In order to find a model that explains the tsunami waveforms, we conduct inversion of the 1896 tsunami waveforms recorded at three tide gage stations. https://doi.org/10.1029/2012JB009186, Iki T (1897) Field survey report of the 1896 Sanriku tsunami.

Cumulative slips on subfaults of the 2011 (red columns) and 1896 (blue) earthquakes. Tsunami 1611 are similar in magnitude to the Tsunami 2011 from the corresponding tsunami deposits found in the Sendai Plain, in the south of Sanriku Coast [41]. However, 35 minutes later the first tsunami wave struck the coast, followed by a second a few minutes later. https://doi.org/10.1002/2017gl075839, Honda K, Terada T, Yoshida Y, Isitani D (1908) Secondary undulations of oceanic tides.

The surface wave magnitude M The deeper subfaults are located closer to the coast than shallowest subfaults, thus the tsunami heights are larger on the coast. 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.’. volume 4, Article number: 33 (2017) Comparison of 6 models a 2011 model with 8 subfaults and 200 km long, b 2011 model with 6 subfaults and 150 km long, c 1896 inversion model, d 1896 final model, e uniform (20 m) slip at 3.5–7 km depth, f uniform (20 m) slip at 0–3.5 km depth. It resulted in two tsunamis which destroyed about 9,000 homes and caused at least 22,000 deaths The data used in this study are from published literature. Tanioka et al. (2004) estimated the seismic velocity structure along the northern Japan Trench by using the wide-angle airgun and ocean bottom seismogram data. Due to higher levels of tsunami awareness, fewer casualties were recorded following the Sanriku earthquake. On 3 March 1933 a tsunami in the Sanriku area reached a height of about thirty meters and killed over 3,000 people. KS made overall design of the study and drafted the manuscript. (2014). Sanriku, Japan The tsunami to hit Sanriku, Japan on June 15th, 1896 was caused by an earthquake of a magnitude 7.6. Most deaths occurred in Iwate and Miyagi although casualties were also recorded from Aomori and Hokkaido. 2014). In Hawaii, wharves were demolished and several houses were swept away. The 8.5 magnitude earthquake occurred at 19: 32 local The 1994 o Red and yellow circles show observed heights by Iki (1897) and Matsuo (1933), respectively. 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. Tsunami heights on the Sanriku coast reported by (a) Iki (1897) and (b) Matsuo (1933) are shown by black circles. In our study area specifically, the 1896 Meiji Sanriku tsunami reached up to ~880 m inland and 16 m in … However, comparative multibeam surveys before and after the 2011 Tohoku earthquake in the northern Japan Trench did not detect large bathymetry change indicating large submarine landslide (Fujiwara et al. w = 8.1. Bull Seismol Soc Am 84:415–425, Aida I (1978) Reliability of a tsunami source model derived from fault parameters. Its direction was ENE–WSW and the nature was extremely slow. This is a typical tsunami earthquake, which generates anomalously larger tsunamis than expected from its seismic waves. The computations are made for 3 h after the origin time with a time step of 0.3 s. 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. Velocity structure profile touched in Takahashi et al. 6) indicates that both faults are located at the contact zone between deformed area (Vp = 3.2–2.6 km/s) and oceanic crust (Vp = 5.3–5.6 km/s), suggesting similarities of fault zone properties. The 1896 Sanriku earthquake (明治三陸地震, Meiji Sanriku Jishin) was one of the most destructive seismic events in Japanese history. They destroyed wharves and swept several houses away.[3][11]. In the present study, the local tsunami amplification observed in Ryori Bay, located on the Sanriku coast of Japan, was investigated using numerical simulations. The geometric standard deviation can be considered as an error factor. (2013b). Its epicenter was ninety miles offshore, near an area of very deep water known as the Japan Trench. The Sanriku earthquake was followed 30 minutes later by a huge tsunami that towered as high as 38.2 meters. Kamaishi in April 2011. It was thus attributed as submarine landslide by Tappin et al. 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. 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. In order to examine the effects of the small slips around the largest one, we trim these smaller slips and compute tsunamis from a uniform 20 m slip model on a 100-km × 25-km fault at a depth of 3.5–7 km (Fig. 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, [1] as demonstrated in the damage caused by the 2011 Tōhoku earthquake and tsunami . Therefore the timing of tsunami arrival at Miyako provides additional important information. Central Meteorological Observatory of Japan, Tokyo, Fujii Y, Satake K, Sakai S, Shinohara M, Kanazawa T (2011) Tsunami source of the 2011 off the Pacific coast of Tohoku Earthquake. The subfaults are placed on the Pacific plate (Nakajima and Hasegawa 2006), and the top depths beneath seafloor are 0 and 3.5 km for shallowest (row 0) and next (row 1) subfaults (Table 1). The slips on the shallowest subfaults along the axis (row 0, depth of 0–3.5 km) are 11–36 m, whereas those on row 1 at the depth of 3.5–7 km range from 1 to 22 m. The average slip for the eight subfaults is 17 m, yielding the seismic moment of 3.5 × 1021 Nm and the corresponding moment magnitude M 1c). 3, Additional file 1: Tables S1, Additional file 2: Table S2). https://doi.org/10.5047/eps.2011.06.010, Fujiwara T, dos Ferreira Santos C, Bachmann AK, Strasser M, Wefer G, Sun T, Kanamatsu T, Kodaira S (2017) Seafloor displacement after the 2011 Tohoku-oki earthquake in the northern Japan Trench examined by repeated bathymetric surveys. Soc Japan) 2(47):89–92 (in Japanese). 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 sum of subfault slip ranges from 20 to 40 m on shallowest subfaults (rows 0). While the 2011 earthquake has a feature of ‘tsunami earthquake’ in the northern part of the source, deeper slip in the southern part of the source caused strong ground shaking, hence the 2011 was not a ‘tsunami earthquake.’. 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. 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. Über 27.000 Menschen kamen um. 1c). Op 15 juni 1896 werd de oostkust van Japan getroffen door een beving van 8,5 op de schaal van Richter. The northeast coast of Honshu, Japan, in Iwate Prefecture, was hit with a powerful earthquake of magnitude 8.4 on March 2, 1933. This is contrary to the 2011 Tohoku earthquake model, which had large slips at shallowest subfaults. No written records of large tsunamis are available before the 1896 event. 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). 2a, Table 1) in the northern and shallow part of the source are adopted. 2013a; Tappin et al. On June 15. Earth Planets Space 63:815–820. It resulted in two tsunamis which destroyed about 9,000 homes and caused at least 22,000 deaths. The moment magnitude M , "On June 15, 1896, nearly 22,000 Japanese lost their lives due to the most devastating tsunami in Japanese history. For the 1896 tsunami heights along the Sanriku coasts, at distances ranging from 170 to 250 km from the epicenter, field surveys were made by three groups (Fig. 1c, Tsuji et al. The slips on surrounding subfaults range 3–7 m, including the shallowest subfaults (0–3.5 km). However, the tsunami heights on the Sanriku coast from the 2011 and 1896 earthquakes were roughly similar (Fig. The suddenly rising waters killed nearly 20,000 people and destroyed countless homes, schools, buildings and bridges. 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.

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. 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. The inversion method is similar to Satake et al. He measured tsunami heights based on various kinds of traces and eyewitness accounts, and assigned different reliabilities depending on the kind of data. Sanriku, Japan 1896 June 15 UTC Magnitude 8.5 Damage extreme. As mentioned in “Tsunami data of the 1896 earthquake,” there is an additional observation of the 1896 Sanriku tsunami: tsunami arrival times at Miyako observatory. The bathymetry data are sampled from J-EGG500 (mesh data with 500 m interval provided by Japan Oceanographic Data Center) and M-7000 series digital bathymetry chart (provided by Japan Hydrographic Association), but newer coastal topography such as breakwater around tide gage stations are removed to reproduce the situation in 1896. https://doi.org/10.1029/2000jb000033, Shuto N, Imamura F, Koshimura S, Satake K, Matsutomi H (2007) Encyclopedia of tsunamis (Tsunami no Jiten). 2007). On June 15, 1896, an earthquake of magnitude 8.5 struck the Sanriku coast on the northeast of Honshu, Japan, in the Iwate Prefecture. However, the computed tsunami waveforms at regional distances (Hanasaki and Choshi) are very similar to the previous model and the observed ones. Posted on 7 września 2020. by. While his report contains 168 diagrams, the reliability of his measurements has been questioned (Shuto et al. Kenji Satake. The Sanriku Coast has periodically been struck by large tsunami. The 1896 Sanriku earthquake was one of the most devastating tsunami earthquakes, which generated an anomalously larger tsunami than expected from its seismic waves. This is a common feature of ‘tsunami earthquakes’ such as the 1992 Nicaragua or 2010 Mentawai earthquakes (Satake and Tanioka 1999; Satake et al. The 1896 Sanriku earthquake (明治三陸地震, Meiji Sanriku Jishin) was one of the most destructive seismic events in Japanese history. During the 2011 Tohoku earthquake, slip on the 1896 asperity (at a depth of 3.5–7 km) was 3–14 m, while the shallower part (depth 0–3.5 km) slipped 20–36 m. Thus the large slips on the plate interface during the 1896 and 2011 earthquakes were complementary. This model is basically similar to that of Tanioka and Satake (1996b), although their average slip is smaller (5.7 m) and the dip angle is larger (20°). 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. These are important issues both in science of tsunami generation in subduction zones, particularly near the trench axis, and also for tsunami hazard assessment. 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. J Geophys Res 84:1561–1568, Article  The tsunami heights along the northern and central Sanriku coasts from both earthquakes were similar, but the tsunami waveforms at regional distances in Japan were much larger in 2011.

Geophys Res Lett. 2013a). Previous studies indicate that the earthquake occurred beneath the accretionary wedge near the trench axis. 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 average slip becomes 14 m, the seismic moment is 2.1 × 1021 Nm, and M S = 7.2 was assigned from global data (Abe 1994). The inversion model (Fig. More than 1,000 people were killed in the Sanriku region in 1933 by another massive earthquake and tsunami. The tsunami heights along the northern and central Sanriku coasts from both earthquakes were similar, but the tsunami waveforms at regional distances in Japan were much larger in 2011. The computed tsunami waveform at Ayukawa, located at the southern Sanriku coast, also becomes larger than the previous model. [2] 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. The ground shaking was felt throughout the Japanese Islands with the maximum seismic intensity of 7 on the Japan Meteorological Agency (JMA) scale, or 11–12 on the Modified Mercalli scale (Fig. Computed tsunami heights on 75 m grids for the four different models are shown by colored lines. [2][9] The damage was particularly severe because the tsunamis coincided with high tides.

A figure much closer to the estimated actual tsunami magnitude. The computed tsunami heights on the southern Sanriku coast become smaller and similar to the observed (Figs. More recently, Lay et al. 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. It occurred along the Japan Trench in the northern tsunami source area of the 2011 Tohoku earthquake where a delayed tsunami … Note that the scale for horizontal axis is location numbers (Additional file 1: Table S1, Additional file 2: Table S2), not distance.

This earthquake is now regarded as being part of a distinct class of seismic events, the tsunami earthquake. On the subfaults where the 1896 slip was large (1B and 1C), the 2011 slips were 3 and 14 m (Fig. & Yamaki, S. Different depths of near-trench slips of the 1896 Sanriku and 2011 Tohoku earthquakes. Tesla Tsunami. We adopt the finite-difference method with the grid interval of 6″ (140 to 190 m). Das Meiji-Sanriku-Erdbeben ( jap. (2004). For comparison, we also test another model of uniform 20 m slip, with the same size, at shallowest (0–3.5 km) part (Fig. The Sanriku coast of Japan is characterized by significant seismic activity. We first adopt the northeastern eight subfaults of the 2011 Tohoku earthquake tsunami source model (Satake et al. 2014), but not recorded on other types (seismographs or high-rate GPS) of data. 2c, 3). Both 1896 and 2011 slips were on the shallowest part of the subduction zone near trench axis, below low velocity prism, If the 2011 northern slip occurred at shallower part than the 1896 source, a question might arise why the 2011 earthquake was not a ‘tsunami earthquake.’ As indicated in Fig. Therefore, it is possible that the fault motion was too slow and weak to be detected on seismic or high-rate GPS data. d Tsunami waveforms from the 1896 Sanriku (blue curves) and 2011 Tohoku (red curves) earthquakes recorded at the three tide gage stations, In the northern part of the 2011 tsunami source, the 15 June 1896 Sanriku earthquake occurred and caused the worst tsunami disaster in Japan, with casualties of ~ 20, 000 (Shuto et al. 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? [7], The unusual disparity between the magnitude of the earthquake and the subsequent tsunami may be due to a combination of forces:[7], Scientists believe the effect of subducted sediment beneath the accretionary wedge was responsible for a slow rupture velocity. This Sanriku tsunami served as an impetus for tsunami research in Japan. Only eight subfaults (0A to 1D: Fig. However, additional tests indicate that the water depth difference makes an insignificant effect for the tsunami heights on the Sanriku coast. The most devastating one, in 1896 (known as the Meiji Sanriku Tsunami) was, until a few days ago, the worst in modern Japanese history. The 1896 Sanriku earthquake was a typical ‘tsunami earthquake’ which caused large tsunami despite its weak ground shaking.
