It resulted in two tsunamis which destroyed about 9,000 homes and caused at least 22,000 deaths 2e). The average slip becomes 14 m, the seismic moment is 2.1 × 1021 Nm, and M 2014). Red curves are observed waveforms and blue curves are computed ones. 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 . Abe K (1979) Size of great earthquakes of 1873–1974 inferred from tsunami data. 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. The geometric mean K becomes 0.93, indicating that observed and computed heights are almost the same, and the geometric standard deviation κ is 1.50. https://doi.org/10.1029/2011JB009133, Matsuo H (1933) Report on the survey of the 1933 Sanriku tsunami. injured hundreds more and destroyed approximately 9,000 homes and 8,000 boats. w was estimated as 8.0–8.2, from a comparison of aftershock activity with other large earthquakes (Utsu 1994). The often-quoted maximum height of 38 m at Shirahama from the 1896 Sanriku tsunami was based on his report. The Tesla Tsunami was also observed across the Pacific. The data used in this study are from published literature. In 1933, another devastating tsunami, with maximum height of 29 m and approximately 3000 fatalities, was caused by the 1933 Sanriku earthquake (M The June 15, 1896 Sanriku earthquake generated devastating tsunamis with the maximum run‐up of 25 m and caused the worst tsunami disaster in the history of Japan, despite its moderate surface wave magnitude (M s =7.2) and weak seismic intensity.

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. For comparison, we also test another model of uniform 20 m slip, with the same size, at shallowest (0–3.5 km) part (Fig. J Geophys Res 117:B707409. Bull Seismol Soc Am 75:135–1154, Omori F, Hirata K (1899) Earthquake measurement at Miyako. 2013b). 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. 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.

In addition, the deeper (3.5–7 km) subfaults produce larger seafloor displacements than surface rupture (top depth of 0 km), hence the tsunami heights are also larger. It was immediately after Meiji Tsunami 1896 when Soshin Yamana, an entrepreneur from A careful manual observation of the tsunami was conducted at the Miyako meteorological observatory (Miyako is shown in Fig. 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. 2002), hence these may correspond to 250–500 years of slip deficit. The Sanriku Coast has periodically been struck by large tsunami. In order to find the best 1896 tsunami source model, we start from the northern part of the 2011 source model, compute the tsunami heights on the Sanriku coast and tsunami waveforms at tide gage stations, and compare them with the 1896 observations. 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. June 15, 1896: The Sanriku Earthquake and Tsunami. This indicates that the 2011 northern slip near the trench axis, delayed ~ 3 min of the main slip near the epicenter, occurred on parts where the 1896 slip was not very large.

More recently, Lay et al. 5). The 2011 tsunami was also recorded at these tide gage stations, although the Ayukawa record went off-scale immediately following the first tsunami arrival at ~ 30 min from the earthquake (Satake et al. The maximum tsunami height was 24 m at Yoshihama. 1611, 1896, 1933, and 2011 tsunamis were particularly large. 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 resulting tsunami was 125.3 feet high in some places, a record height until the 11 March 2011 tsunami, which reached 127.6 feet high in the town of Aneyoshi, in Iwate prefecture. 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. Pub Earthq Invest Comm 26:1–113, Ide S, Baltay A, Beroza GC (2011) Shallow dynamic overshoot and energetic deep rupture in the 2011 M s 8.5). Because the eight subfaults of the 2011 model produced larger tsunami heights than the observed values on the southern Sanriku coast, we drop the southernmost subfaults (0D and 1D), and adopt the six subfaults.

The 1896 Sanriku earthquake (明治三陸地震, Meiji Sanriku Jishin) was one of the most destructive seismic events in Japanese history. Seafloor displacement is calculated for a rectangular fault model in an elastic half-space (Okada, 1985). Among historical tsunamis, it is known that the AD 1611, 1896, 1933, and 2011 tsunamis were particularly large. 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. This revised fault model gave a magnitude of Mw =8.0–8.1. The Computed tsunamis from the northeastern part of the 2011 tsunami source model roughly reproduced the 1896 tsunami heights on the Sanriku coast, but were much larger than the recorded tsunami waveforms. https://doi.org/10.1007/s00024-014-0779-x, Unohana M, Ota T (1988) Disaster records of Meiji Sanriku tsunami by Soshin Yamana. 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. 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. w = 8.1. 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 tsunami magnitude M This model reproduces tsunami waveforms at regional distances but underestimates the Sanriku tsunami heights, particularly on the southern Sanriku coast. 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). Science 332:1426–1429. 2013b). On the contrary, the largest tsunami heights on the Sanriku coast, ~ 40 m, were recorded ~ 100 km north (near 39.6°N).

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. 2014) as detailed in the “Tsunami data of the 1896 earthquake.”, Tsunami waveform modeling of the 1896 Sanriku earthquake has shown that slip occurred on a narrow fault located near the trench axis (Tanioka and Satake 1996b; Tanioka and Seno 2001). 2011 and AD 1896 Meiji Sanriku tsunamis, considering the landward extent of each tsunami deposit. No written records of large tsunamis are available before the 1896 event.  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. ” Hey Japan? In the present study, the local tsunami amplification observed in Ryori Bay, located on the Sanriku coast of Japan, was investigated using numerical simulations. At about 20 h, the water rose, but fell somewhat in a few minutes. Über 27.000 Menschen kamen um. 1908; Imamura and Moriya 1939). 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. To model the 1896 tsunami source, we started from the northern subfaults of the 2011 Tohoku earthquake model, and modified them to obtain the final fault model. The computed tsunami waveform at Ayukawa, located at the southern Sanriku coast, also becomes larger than the previous model. , The unusual disparity between the magnitude of the earthquake and the subsequent tsunami may be due to a combination of forces:, Scientists believe the effect of subducted sediment beneath the accretionary wedge was responsible for a slow rupture velocity.

The power of the tsunami was great: large numbers of victims were found with broken bodies or missing limbs. While the tsunami heights on the northern and central Sanriku coasts were similar for the two tsunamis, the tsunami heights on the southern Sanriku coast and the tsunami waveforms at regional distances were smaller for the 1896 earthquake. On June 15, 1896, an earthquake of magnitude 8.5 struck the Sanriku coast on the northeast of Honshu, Japan, in the Iwate Prefecture. 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. The computed tsunami heights on the southern Sanriku coast become smaller and similar to the observed (Figs. Polet and Kanamori (2000) extended this model to global subduction zones, based on the examination of the source spectra of large (M > 7) earthquakes in the 1990s. 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 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 damage was particularly severe because the tsunamis coincided with high tides. 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. "On June 15, 1896, nearly 22,000 Japanese lost their lives due to the most devastating tsunami in Japanese history.

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.’. Juni 1896. 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. Approximately 30 minutes later a devastating tsunami struck the Sanriku Coast. In addition, the tsunami arrival times were measured relative to the earthquake. Pure Appl Geophys 170:1567–1582. The geometric standard deviation can be considered as an error factor. The tsunami waveform from the 1896 final model shows initial negative wave followed by the positive wave with an amplitude of ~ 3.4 m at around 35 min. We use the subfault configuration of the 2011 Tohoku earthquake of Satake et al. KS made overall design of the study and drafted the manuscript. This work was partially supported by JSPS KAKENHI Grant Number JP16H01838.

Geophys Res Lett 23:861–864, Tanioka Y, Satake K (1996b) Fault parameters of the 1896 Sanriku tsunami earthquake estimated from tsunami numerical modeling. The local tsunami sizes are comparable to the AD 2011 and AD 1896 Meiji Sanriku tsunamis, considering the landward extent of each tsunami deposit. Earth Planets Space 63:815–820. The average slip on the eight subfaults is 8 m, yielding the seismic moment of 1.6 × 1021 Nm and the moment magnitude of M In recent times, the great Meiji Sanriku tsunami of 15 June 1896 resulted in 27,122 deaths, thousands of injuries, and the loss of thousands of homes. The geometric mean K is 1.87, and the geometric standard deviation κ is 1.46. To quantify the comparison, the geometric mean K and geometric standard deviation κ of observed and computed heights (Aida 1978) are computed. 2014). 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. Thus the slip distributions on shallow parts of plate interface were different for the 1896 Sanriku and 2011 Tohoku earthquakes. Because of the sawtooth-shaped topography of the Sanriku coast, often called a ria-type coast in Japan, both the 1896 and 2011 tsunami heights significantly change at short distance (Fig. The computed tsunami heights are similar to the observed heights on the northern Sanriku coast, but larger than those on the southern coast (Figs. While his report contains 168 diagrams, the reliability of his measurements has been questioned (Shuto et al. 2a, Table 1) in the northern and shallow part of the source are adopted. Large earthquakes have generated destructive tsunamis in the past. We also consider the effects of horizontal displacement on a steep bathymetric slope (Tanioka and Satake 1996a). The 1896 Meiji-Sanriku earthquake was highly destructive, generating the most devastating tsunami in Japanese history, destroying about 9,000 homes and causing at least 22,000 deaths.
