Sanriku, Japan The tsunami to hit Sanriku, Japan on June 15th, 1896 was caused by an earthquake of a magnitude 7.6. Many villagers were at the beach celebrating two events when the earthquake occurred: the return of soldiers from a successful war with China, the first Sino-Japanese War of 1894, and the annual Boys’ Festival. Thirty-five minutes after the earthquake, the most devastating tsunami in Japan’s history reached the shore at the same time as high tide. On June 15, 1896, an earthquake of magnitude 8.5 struck the Sanriku coast on the northeast of Honshu, Japan, in the Iwate Prefecture. They had installed tidal embankments, trees, and escape roads. [6], The tsunami reached its maximum estimated height of about 20 meters at Ōfunato, Iwate. This is a typical tsunami earthquake, which generates anomalously larger tsunamis than expected from its seismic waves. In this section, we will distinguish between the earthquakes by referring to them as the Meiji (1896) earthquake and the Showa (1933) earthquake. 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 1896 Sanriku earthquake was one of the most destructive seismic events in Japanese history. Consequently, the disaster caused by earthquake is also known as the "Keicho Sanriku tsunami earthquake". George Pararas-Carayannis. N1 - Funding Information: ACKNOWLEDGEMENTS We are grateful to Hiroo Kanamori for sending us a preliminary write up of his solution for the moment of the 1933 earthquake, and to Naoki Uchida for collaboration and a data set … There were also reports of unusual phenomenon on that same day—low water levels in wells and large numbers of tunas every day. Both earthquakes generated the tsunami that caused enormous damage. The Sanriku region was the most affected area in Japan. The earthquake and subsequent tsunamis destroyed 9,000 homes and caused approximately 22,000 deaths. The Meiji-Sanriku earthquake in 1896 occurred in the same area as the Tohuku earthquake in 2011. This boundary has been associated with a series of large historical earthquakes, originating either from rupture along the plate interface or from deformation within either the over-riding or subducting plates, many of them triggering a destructive tsunami, such as the 1896 Meiji-Sanriku earthquake. ABSTRACT: The Tohoku region in Japan was hit by a gigantic earthquake of M=9.0 subsequently followed by a huge tsunami which occurred off the Pacific ocean. The Sanriku Coast has periodically been struck by large tsunami. Its epicenter was ninety miles offshore, near an area of very deep water known as the Japan Trench. Professor Kazuomi Hirakawa of Hokkaido University has found tsunami deposits on the southern part of Hokkaido and northern Sanriku from the early part of the 17th century. 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. ... Honshu, immediately west of the Japan Trench, but caused only mild shaking and no damage—and did … The recurrence of major seismic activity continues in the 21st century. On June 15, 1896, an earthquake of magnitude 8.5 struck the Sanriku coast on the northeast of Honshu, Japan, in the Iwate Prefecture. The Japanese Red Cross Society and the Nurse Association sent doctors and nurses to treat the injured. Your email address will not be published. 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 magnitude of the earthquake was 8.1Ms. However, due to the time delay of nearly four hours before the tsunami arrived, there are questions about the exact location of the source. Earthquake on January 17, 1995, when an elevated section of the Sanyo Shinkansen fell and concrete dropped from a tunnel wall. About 5,000 houses in Japan were destroyed, of which nearly 3,000 were washed away. The earthquake had an estimated magnitude of at least 8.4 on the moment magnitude scale, but may have been as high as 9.0, similar to the 2011 Tōhoku earthquake and tsunami. The military authorities also sent soldiers to secure public order, military engineers to recover bodies from the rubble, and the navy to search the water for bodies of the victims. T2 - A global seismological reassessment. The earthquake caused a tsunami and killed over 27,000 people.DetailsThe earthquake had a magnitude of 8.5 and the tsunami wave was over 80 feet tall.FactsIt was the first tsunami ever recorded!penGuins.comWhen it occured19:32 (local time) on June 15, … In 1937, another very strong tsunami hit the coast of Sanriku. Twenty-six thousand people were killed and nine thousand homes destroyed. Hence the relation between the 1896 and 2011 tsunami sources is an important scientific as well as … At times the tsunami’s wave reached a height of 125 feet. The 869 Sanriku earthquake (貞観地震, Jōgan jishin) and associated tsunami struck the area around Sendai in the northern part of Honshu on 9 July (26th day of 5th month, 11th year of Jōgan). Precise locations of earthquakes in the source areas … The northeast coast of Honshu, Japan, in Iwate Prefecture, was hit with a powerful earthquake of magnitude 8.4 on March 2, 1933. The ... the depth of the surface layer and the damage of the house. The people remained with no homes, security and protection. (1) On the evening of June 15, communities along the coast of Sanriku were celebrating the Shinto holiday and the return of soldiers from the Sino-Japanese War. The impact of this tsunami carried across the Pacific. The strong power of the earthquake caused a tsunami with almost 30 m height. The initial shock occurred on at 0230 AM on March 2, 1933. The 1933 Sanriku earthquake (昭和三陸地震, Shōwa Sanriku Jishin) occurred on the Sanriku coast of the Tōhoku region of Honshū, Japan on March 2 with a moment magnitude of 8.4. Melgar points to the 1933 Sanriku earthquake in Japan, which came in at a magnitude 8.5, as a good example of one of these intraslab normal quakes. Houses Heavily Damaged by the Sanriku Earthquake . Leave a Comment / Natural / By devastating. Other things listed in the booklet included avoiding the recession of the tsunami’s first wave and being prepared to evacuate the coast quickly and move to higher ground. A great earthquake occurred on March 2, 1933 (UTC DATE) in the Sanriku region of Japan and generated a destructive tsunami that caused extensive damage along the Sanriku coast of the Tohoku region of the island of Honshu. 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. Both of them have caused huge damage on the eastern coast of Japan, having a huge inundation area more than 500km2with the attack of destructive wave forces. The tsunami caused by the earthquake caused most of the casualties, however the earthquake did some damage. Sanriku is still on the way of recovery from the Great East Japan Earthquake in 2011 and the typhoon in 2019 caused great damage again on the Sanriku Railway, which was originally built to deliver goods to areas isolated due to disasters and is now a symbol of recovery. Required fields are marked *. At about 10:30 on December 2, 1611 (Keichō 16, 10th month, 28th day), there was a severe earthquake, and at about 14:00 (local time), this was followed by a devastating tsunami. The earthquake had an estimated magnitude of at least 8.4 on the moment magnitude scale, but may have been as high as 9.0, similar to the 2011 Tōhoku earthquake and tsunami. The 1896 Sanriku earthquake was one of the most destructive seismic events in Japanese history. This booklet included a warning about weak earthquake shocks, the kind of event that was so much misunderstood in 1896. JR East conducted urgent reinforcement work to improve quake resistance on shinkansen lines in the Tokyo metropolitan and Sendai areas and later in all areas following the South Sanriku Earthquake on May 26, 2003. This was the reason behind the tsunami following the Tohoku earthquake that causes the Pacific plate to move under the North American plate. ... as in the 1896 Sanriku earthquake. The 1896 Sanriku earthquake (明治三陸地震, Meiji Sanriku Jishin) was one of the most destructive seismic events in Japanese history. Tsunamis generated by both earthquakes caused severe damage along the Sanriku coast. In 1933, Japan was shacked by a strong earthquake, with a 8.5 Richter power. The term intraplate earthquake refers to a variety of earthquake that occurs within the interior of a tectonic plate; this stands in contrast to an interplate earthquake, which occurs at the boundary of a tectonic plate. At the same time it pointed out that a loud noise like thunder might indicate an approaching tsunami. Sanriku, Japan The tsunami to hit Sanriku, Japan on June 15th, 1896 was caused by an earthquake of a magnitude 7.6. It resulted in two tsunamis which destroyed about 9,000 homes and caused at least 22,000 deaths. The Sanriku coast has a well-documented history of significant seismic activity. Amongst the worst affected places was Ōtsuchi, with 800 deaths. 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. T2 - A global seismological reassessment. Maximum wave heights of 28.7 m … THE EARTHQUAKE. Numerical Simulations of Large-Scale Sediment Transport Caused by the 2011 Tohoku Earthquake Tsunami in Hirota Bay, Southern Sanriku Coast. The Sanriku coast was severely damaged not only by the 2011 Tohoku tsunami, but also by the tsunamis that followed the 1933 Showa Sanriku and 1896 Meiji Sanriku earthquakes. Its epicenter on a reverse fault near the Japan Trench was the reason for the mild impact felt on shore. Usually victims in tsunami disasters die by drowning but, in the Sanriku tsunami, there was extensive damage to the bodies of victims; fractured skulls, bodies heavily scarred, and legs and arms broken. The tsunami caused widespread flooding of the Sendai plain. Sanriku Earthquake in the past about 30 years in two large earthquakes. Norway tear Northern Ireland's second-string defence apart in Windsor Park thrashing The governmental agencies employed inspectors on the scene to assess ad record (Case). The damage from the tsunami far exceeded that from the earthquake, so this is considered to be a tsunami earthquake. The emperor delegated one person to visit the disaster site and cheer up the survivors with encouraging words. The common feature of the damage that Hachinohe City had received in two large earthquakes was examined. Shallow earthquakes cause the most damage because the focus is near where people live. Types of Earthquakes in Japan It would have been very similar to the 1605 Keichō Nankaidō earthquake, a tsunami earthquake in the Nankai Trough area. The 1896 Sanriku earthquake (明治三陸地震, Meiji Sanriku Jishin) was one of the most destructive seismic events in Japanese history. The 1933 earthquake was the largest earthquake hitherto ever reported among normal fault earthquakes, with Mw = 8.5 (Okal et al. AU - Kirby, Stephen H. AU - Kalligeris, Nikos. The 8.5 magnitude earthquake occurred at 19: 32 local The 1994 o With this earthquake, the area along the Pacific Ocean in what is currently called the Sanriku Coast did shake strongly, but only about 4-5 on the Shindo scale. AU - Okal, Emile A. Devastation caused by the tsunami at Sanriku . In 2:30:48 March 3, 1933, Showa Sanriku earthquake, occurs as a seismic source (7.7 minutes north latitude 39 degrees, 7 minutes east longitude 144 degrees) Kamaishi City, 200km east Okiyaku the have. The sharp bend of the lithosphere is therefore a result, not the cause, of great earthquakes beneath oceanic trenches. The Sanriku region was the most affected area in Japan. The unusual disparity between the magnitude of the earthquake and the subsequent tsunami may be due to a combination of forces: 1. the tsunami was caused by a slope failure triggered by the earthquake 2. the rupture velocity was unusually low. Most … The 1896 Sanriku earthquake was a typical ‘tsunami earthquake’ which caused large tsunami despite its weak ground shaking. In California a 9.5 foot-high wave arrived. The 1611 Sanriku earthquake ... Consequently, the disaster caused by earthquake is also known as the "Keicho Sanriku tsunami earthquake". The earthquake from March 2, 1933, led to many damages and 3000 victims. The 1896 Sanriku earthquake was one of the most devastating tsunami earthquakes, which generated an anomalously larger tsunami than expected from its seismic waves. Hence the relation between the 1896 and 2011 tsunami sources is an important scientific as well as … In the northern part of the Japan Trench, the 1933 Showa-Sanriku earthquake (M w 8.4), an outer-trench, normal-faulting earthquake, occurred 37 yr after the 1896 Meiji-Sanriku tsunami earthquake (M w 8.0), a shallow, near-trench, plate-interface rupture. Preventive coastal measures were not implemented until after another tsunami struck in 1933. 2016 ). The estimated rupture area for the earthquake is similar to that calculated for the 1933 Sanriku earthquake.[5]. INTRODUCTION. The source of the earthquake was off the north coast of Sanriku. Earthquake title=1933 Sanriku earthquake date= March 2 1933 magnitude = 8.4 M w depth= location= countries affected = flag|Japan flag|United States tsunami = Yes casualties = at least 3000 dead The 1933 Sanriku earthquake occurred on March 2, 1933 off the coast of Sanriku, in the Tōhoku region of Honshu, Japan.The earthquake measured 8.4 on the moment magnitude scale. However, it took a further thirty years before action was taken on detailed preventive measures. (1) (1) On the evening of June 15, communities along the coast of Sanriku were celebrating the Shinto holiday and the return of soldiers from the Sino-Japanese War. Therefore, the tsunami are referred to separately as the Meiji Sanriku Earthquake Tsunami and the Sanriku Earthquake Tsunami. 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. In the vertical cross section of crust, there are two features labeled—the focus and the epicenter, which is directly above the focus. However, it is the epicenter of an earthquake that is reported by scientists and the media (figure 1). [4], National Centers for Environmental Information, "Catalog of Damaging Earthquakes in the World", "Danger in the Lowground: The Japan Earthquake in Historical Context", "Triple Seismic Zone and the Regional Variation of Seismicity along the Northern Honshu Arc", "図１６　１６１１年１２月２日の慶長三陸地震の津波波高分布と震度分布（羽鳥，１９７５ｂ）", https://en.wikipedia.org/w/index.php?title=1611_Sanriku_earthquake&oldid=984437221, Articles containing Japanese-language text, Creative Commons Attribution-ShareAlike License, This page was last edited on 20 October 2020, at 02:44. The first wave receded back out to sea and returned in a second wave five minutes later. The offshore earthquake, though powerful, was barely felt on shore so no one was prepared for the tsunami that followed. There was little awareness of the earthquake because of its distance from shore and because of its character, but the tsunami that ensued was massive and did overwhelming damage on shore and killed 26,000 people. The 1933 Sanriku earthquake (昭和三陸地震, Shōwa Sanriku Jishin) occurred on the Sanriku coast of the Tōhoku region of Honshū, Japan on March 2 with a moment magnitude of 8.4. 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. Sanriku Earthquake – Japan – March 2, 1933. The governmental agencies dispatched inspectors and the army sent medical specialists. Date and Origin Time - March 3, 1933 at 02:31 AM (Japan Standard Time); March 02 at 17:31 UTC. The tsunami caused … Tsunamis generated by both earthquakes caused severe damage along the Sanriku coast. A great earthquake occurred on March 2, 1933 (UTC DATE) in the Sanriku region of Japan and generated a destructive tsunami that caused extensive damage along the Sanriku coast of the Tohoku region of the island of Honshu. The 1611 Sanriku earthquake (慶長三陸地震, Keichō Sanriku Jishin) occurred on December 2, 1611, with an epicenter off the Sanriku coast in Iwate Prefecture. AU - Kirby, Stephen H. AU - Kalligeris, Nikos. The 1933 Sanriku earthquake (昭和三陸地震, Shōwa Sanriku Jishin) occurred on the Sanriku coast of the Tōhoku region of Honshū, Japan on March 2 with a moment magnitude of 8.4. Thrust faulting, which causes one tectonic plate diving under another and dragging other plates on the top due to that shifting, is the culprit that triggers a tsunami. The 869 Sanriku earthquake and its associated tsunami struck the area around Sendai in the northern part of Honshu on 9 July 869 AD. The associated tsunami caused widespread damage. The 1896 Sanriku earthquake was a typical ‘tsunami earthquake’ which caused large tsunami despite its weak ground shaking. A major earthquake in the 19th century caused more than 20,000 deaths, and another in the 20th century caused thousands more. It is possible that the earthquake and tsunami in Sanriku was an enormous quake that resonated even in the area of the Kurile Trench off the eastern coast of Hokkaido. It has been estimated that the … In Hawaii, wharves were demolished and several houses swept away. 1896Sanriku, JapanEarthquakeWhere it happened...Sanriku is located on the North coast of Japan.DescriptionThe damage was extreme. The earthquake had an estimated magnitude of at least 8.4 on the moment magnitude scale, but may have been as high as 9.0, similar to the 2011 Tōhoku earthquake and tsunami. Unfortunately, in spite of the long history of tsunamis on this coast, very little beyond immediate humanitarian assistance was done by public authorities. Figure 1. In the northern part of the Japan Trench, the 1933 Showa-Sanriku earthquake (M w 8.4), an outer-trench, normal-faulting earthquake, occurred 37 yr after the 1896 Meiji-Sanriku tsunami earthquake (M w 8.0), a shallow, near-trench, plate-interface rupture. 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. Everything in its path was totally devastated. Houses Heavily Damaged by the Sanriku Earthquake . The … The epicenter was located offshore, 290 kilometres (180 mi) east of the city of Kamaishi, Iwate.The main shock occurred at 02:31 AM local time on March 3, 1933 (17:31 UTC March 2, 1933) and measured 8.4 on the moment magnitude scale. It was followed by a tsunami that reached heights of seventy feet, … ... at Ōfunato, Iwate, caused extensive damage, destroyed many homes and caused numerous casualties The tsunami destroyed over 7,000 homes along the northern Japanese coastline, … The earthquake measured 8.4 on the moment magnitude scale [1] and was in approximately the same location as the 1896 Meiji-Sanriku earthquake. … The source of the earthquake was off the north coast of Sanriku. The focal process of the Sanriku earthquake of March 2, 1933, is discussed in relation to the bending mechanism of the lithosphere. The violence of the tsunami was yet another unusual feature of the day. It resulted in two tsunamis which destroyed about 9,000 homes and caused at least 22,000 deaths. After reporting to the Meiji emperor, the minister of the Interior Ministry contacted all ministries to deliver relief and rescue for the tsunami victims. The initial shock occurred at 0231 AM local time on March 3, 1933 (1731 GMT March 2, 1933). The 1896 Sanriku earthquake was one of the most destructive seismic events in Japanese history. The earthquake lasted for five minutes and was accompanied by a slow shaking. The Sanriku Coast has periodically been struck by large tsunami. It was in approximately the same location as the 1896 Sanriku earthquake and it occurred far enough away from the town that shaking did little damage. Sanriku (三陸), sometimes known as Rikushū (陸州), lies on the northeastern side of the island of Honshu, corresponding to today's Aomori, Iwate and parts of Miyagi Prefecture and has a long history.. [13] Earthquake Clusters. The associated tsunami caused widespread damage. The recurrence of major seismic activity continues in the 21st century. This earthquake is now regarded as being part of a … A description of this event in an official diary from 1612 is probably the first recorded use of the term 'tsunami'.[4]. Villagers observed minor shocks in the earlier part of the day, many hours before the earthquake. The epicenter of the 1933 Sanriku earthquake was located offshore, 290 kilometres (180 mi) east of the city of Kamaishi, Iwate. This time the local authorities were better prepared for it. 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 Sanriku coast has a well-documented history of significant seismic activity. The associated tsunami caused widespread damage. The 8.5 magnitude earthquake occurred at 19: 32 local The 1994 o The impact on shore was much weaker than would normally be expected from such a powerful earthquake so there was little expectation of a tsunami, even though this part of the Japanese coast experiences earthquakes frequently. The 1896 Sanriku earthquake (明治三陸地震, Meiji Sanriku Jishin) was one of the most destructive seismic events in Japanese history. Earthquake title=1933 Sanriku earthquake date= March 2 1933 magnitude = 8.4 Mw depth= location= countries affected = flag|Japan flag|United States tsunami = Yes casualties = at least 3000 dead The 1933 Sanriku earthquake occurred on March 2, 1933. 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. T1 - The Showa Sanriku earthquake of 1933 March 2. It would have been very similar to the 1605 Keichō Nankaidō earthquake, a tsunami earthquake in the Nankai Trough area. Sanriku is still on the way of recovery from the Great East Japan Earthquake in 2011 and the typhoon in 2019 caused great damage again on the Sanriku Railway, which was originally built to deliver goods to areas isolated due to disasters and is now a symbol of recovery. (adsbygoogle = window.adsbygoogle || []).push({}); Your email address will not be published. The people remained with no homes, security and protection. The earthquake from March 2, 1933, led to many damages and 3000 victims. Because this earthquake occurred about 290 km (180 mi) off the coast of Honshu, most of the casualties and damage were caused by the large tsunami that was generated, instead of directly from the earthquake itself. JAPAN - EARTHQUAKE AND TSUNAMI OF 3 MARCH 1933 IN SANRIKU. A major earthquake in the 19th century caused more than 20,000 deaths, and another in the 20th century caused thousands more. It was pointed out recently that sediments near a toe of an inner trench slope with a large horizontal movement due to the … About 5,000 houses in Japan were destroyed, of which nearly 3,000 were washed away. The earthquake and subsequent tsunamis destroyed 9,000 homes and caused approximately 22,000 deaths. The 869 Sanriku earthquake (貞観地震, Jōgan jishin) and its associated tsunami struck the area around Sendai in the northern part of Honshu on 9 July 869 AD (or the 26th day of the 5th month in the 11th year of Jōgan). The 1896 Sanriku earthquake was one of the most destructive seismic events in Japanese history. Previous studies indicate that the earthquake occurred beneath the accretionary wedge near the trench axis. According to old documents, the earth shook violently three times. The associated tsunami caused widespread damage. 2016 ), and it caused a large tsunami that resulted in 3000 deaths (Uchida et al.

AU - Okal, Emile A. It was shown that the position where the damage building caused by both earthquakes was distributed was almost the same by this investigation. The 869 Sanriku earthquake (貞観地震, Jōgan jishin) and associated tsunami struck the area around Sendai in the northern part of Honshu on 9 July (26th day of 5th month, 11th year of Jōgan). After the quake’s shack, there continued … The 1896 Sanriku earthquake was one of the most destructive seismic events in Japanese history. T1 - The Showa Sanriku earthquake of 1933 March 2. Download this stock image: Japan, Sanriku Earthquake and Tsunami, 1933 - HRNTTT from Alamy's library of millions of high resolution stock photos, illustrations and vectors. At about 10:30 on December 2, 1611 (Keichō 16, 10th month, 28th day), there was a severe earthquake, and at about 14:00 (local time), this was followed by a devastating tsunami. The 1896 Sanriku earthquake was one of the most destructive seismic events in Japanese history. 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. Maximum wave heights of 28.7 m (94 ft) were observed at Ryori Bay, Honshu. The earthquake had an estimated magnitude of at least 8.4 on the moment magnitude scale, but may have been as high as 9.0, similar to the 2011 Tōhoku earthquake and tsunami. [8] According to old documents, 1,783 people were killed in the Sendai Domain, and over 3000 horses and men in the Nanbu and Tsugaru domains. On the southern coast of Hokkaido, many Ainu were also drowned ("Hokkaido History"). This earthquake resulted in two tsunamis caused destruction of 9000 homes and at least 22000 deaths. Ancient [7], The tsunami struck on the east coast of Sanriku from Sendai bay in the south to southeastern Hokkaido in the north, a greater length of coastline than was affected by the 1896 tsunami. [1][3] It triggered a devastating tsunami. They also prepared a booklet on precautions for preventing a disaster. According to old documents, the earth shook violently three times.
