sanriku japan tsunami 1896

(2012) classified the seismogenic zone of subduction zones into four domains and assigned the shallowest domain (A: less than 15 km depth) as a source region of ‘tsunami earthquakes.’. 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°). J Phys Earth 26:57–73, Central Meteorological Observatory (1902) On the earthquakes in the year 1896 in annual report. Science 332:1426–1429. The 1896 Sanriku earthquake was a typical ‘tsunami earthquake’ which caused large tsunami despite its weak ground shaking. 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 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. In the present study, the local tsunami amplification observed in Ryori Bay, located on the Sanriku coast of Japan, was investigated using numerical simulations. 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. Japan 1896 Meiji-Sanriku earthquake Location: The epicenter of this earthquake lies just to the west of the Japan Trench , the surface expression of the west-dipping subduction zone that forms part of the convergent boundary between the Pacific and Eurasian plates. It was followed by a tsunami that reached heights of seventy feet, causing catastrophic destruction to countless homes and ships and taking the lives of … 2b). 2014), but not recorded on other types (seismographs or high-rate GPS) of data.

The Sanriku Coast has periodically been struck by large tsunami. 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 … 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. 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. He measured tsunami heights based on various kinds of traces and eyewitness accounts, and assigned different reliabilities depending on the kind of data. b Epicenter and seismic intensity distribution of the 1896 Sanriku 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. Japan 1896 Meiji-Sanriku earthquake Location: The epicenter of this earthquake lies just to the west of the Japan Trench , the surface expression of the west-dipping subduction zone that forms part of the convergent boundary between the Pacific and Eurasian plates. Large earthquakes have generated destructive tsunamis in the past. 1896 Meiji-Sanriku earthquake damage and effects in Kamaishi, Iwate‎ (7 F) Media in category "1896 Meiji-Sanriku earthquake" The following 5 files are in this category, out of 5 total. California Privacy Statement, (2014). The lower death rate in 1933 reflects, in part, the precautions taken after 1896 earthquake to cope with possible future earthquakes and tsunamis. This Sanriku tsunami served as an impetus for tsunami research in Japan. https://doi.org/10.1016/j.margeo.2014.09.043, Tsuji Y, Satake K, Ishibe T, Harada T, Nishiyama A, Kusumoto S (2014) Tsunami heights along the Pacific coast of Northern Honshu recorded from the 2011 Tohoku and previous great earthquakes. However, the computed tsunami waveforms at regional distances are much larger than the recorded ones, particularly at Hanasaki and Ayukawa (Fig. Earth Planets Space 63:815–820. J Geophys Res 117:B04311. More than 1,000 people were killed in the Sanriku region in 1933 by another massive earthquake and tsunami. 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. Kamaishi has been periodically hit by tsunami over the centuries, including the ones that struck the Sanriku Coast in 1896 and 1928. However, the tsunami heights on the Sanriku coast from the 2011 and 1896 earthquakes were roughly similar (Fig. 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. Computed tsunami heights on 75 m grids for the four different models are shown by colored lines. (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. Sanriku, Japan 1896 June 15 UTC Magnitude 8.5 Damage extreme. t was determined as 8.6 from global data (Abe 1979) and 8.2 from Japanese data (Abe 1981). The slips on surrounding subfaults range 3–7 m, including the shallowest subfaults (0–3.5 km). Velocity structure profile touched in Takahashi et al. It describes as follows. We thank Dr. David Tappin and an anonymous reviewer for their critical comments on the original manuscript, which helped us to improve the paper. Previous studies indicate that the earthquake occurred 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. 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. The surface wave magnitude M We adopt the finite-difference method with the grid interval of 6″ (140 to 190 m). 1b, Honda et al. Note that the scale for horizontal axis is location numbers (Additional file 1: Table S1, Additional file 2: Table S2), not distance. Did both earthquakes rupture the same shallow plate interface or different parts? w = 8.2. While this is slightly smaller than the observed value, the timing is similar to the reported. It is estimated that 27,000 people lost their lives. On the contrary, the largest tsunami heights on the Sanriku coast, ~ 40 m, were recorded ~ 100 km north (near 39.6°N). Sediment effect on tsunami generation of the 1896 Sanriku tsunami earthquake Yuichiro Tanioka Seismology and Volcanology Research Department, Meteorological Research Institute, Tsukuba 305-0052, Japan Tetsuzo Seno Earthquake Research Institute, University of Tokyo, Tokyo 113-0032, Japan Abstract. 2e). 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.
