[29][30], On 23 April 2011, the Prime Minister of Australia, Julia Gillard, visited Minamisanriku.[31]. Characteristics of Sanriku tsunamis. In the 2011 Tohoku tsunami, the maximum run‐up height was 39.7 m at Miyako, which resulted in catastrophic destruction of towns and cities in the ria coast area. Past tsunami impacts were fairly moderate south of the Otsuchi Peninsula, so the area lacked the extensive defense walls found farther north. The tsunami was also recorded in Hawaii with a height of 9.5 feet (2.9 m), and also resulted in slight damage. The clinic was active in treating patients immediately upon opening. [26][27], The town is the site of the first field hospital established by an outside nation offering assistance following the disaster. The maximum height for the 1896 and the 1833 tsunamis occurred at Ryori Bay in Sanriku, Iwate Prefecture. An approximately 13-meter high tsunami hit a building at Kesennuma Koyo High School. All the others have gone." The 2011 Tohoku Earthquake Tsunami Joint Survey (TTJS) Group reported that tsunami height was 22.84 m near the shoreline at this site and reached up to ~ 720 m inland and 12 m in elevation (http://www.coastal.jp/ttjt/) (Fig. Keywords: Paleo-tsunami, Sanriku coast, Japan, Tsunami deposit identification, AD 869 Jogan tsunami, Storm wave, Numerical modeling Introduction The Tohoku-oki earthquake (Mw=9.0) and tsunami that struck on March 11, 2011, generated severe damage along the Pacific coast of eastern Japan. Minamisanriku (南三陸町, Minamisanriku-chō) is a town in Miyagi Prefecture, Japan. [24], Miki Endo, a 25-year-old employed by the town's Crisis Management Department to voice disaster advisories and warnings, was hailed in the Japanese news media as a heroine for sacrificing her life by continuing to broadcast warnings and alerts over the community loudspeaker system, in the Crisis Management Department's building, as the tsunami overwhelmed it. SANRIKU EARTHQUAKE IN JAPAN George Pararas-Carayannis Tsunami Society International, Honolulu, Hawaii, USA drgeorgepc@yahoo.com ABSTRACT The great Tohoku earthquake of March 11, 2011 generated a very destructive and anomalously high tsunami. In 1933, another devastating tsunami, with maximum height of 29 m and approximately 3000 fatalities, was caused by the 1933 Sanriku earthquake ( M s 8.5). Its epicenter on a reverse fault near the Japan Trench was the reason for the mild impact felt on shore. The Memorial Museum was built on the site of that high school to retain the state of the damage at that time. The tsunami that struck north-east Japan in March rose to a maximum height of 132.5ft, according to researchers, taller than Rio's Christ the Redeemer. Later, the waves of the Tsunami enveloped the entire city as the water of Lake Biwa rose, leaving no trace of the place, except for the castle situated there. Meiji Sanriku Jishin This quake occurred off the coast of Sanriku in Iwate Prefecture, which caused a tsunami of 25 m (82 ft) to strike 35 minutes after the quake, destroying hundreds of houses and killed over 22,000 people. The tsunami was reported at Shirahama to have reached a height of 38.2 m, causing damage to more than 11,000 homes and killing some 22,000 people. [28] A 53-member delegation of medical personnel from the Home Front Command and the IDF's Medical Corps opened a field hospital near Minamisanriku on March 29. An initial team of five doctors from Israel set up a surgery in preparation for a larger team once needs were assessed. There were around 7,000 of us on the hill that day. In the latter method, we dipped the test pit and observed the soil layer of the side wall minutely to find the sand layer being supposed to be carried by the tsunami from the dune. Twenty-six thousand people were killed and nine thousand homes destroyed. To mark the 30th anniversary of the disaster in 1990, a bilingual Spanish-Japanese plaque was installed, with a message from President Patricio Aylwin of Chile, accompanied by a replica moai statue. Zisin (Journal of the Seismological Society of Japan), Zisin (Journal of the Seismological Society of Japan. Per Japanese census data,[5] the population of Minamisanriku peaked in the 1950s and has declined steadily over the past 70 years. In Hawaii, wharves were … [3], Minamisanriku has a humid climate (Köppen climate classification Cfa) characterized by warm humid summers and cold winters. [16] In late June 2011, a total of 1,206 were counted as dead or missing, according to the Kahoku Shinpou. The maximum coastal tsunami height was nearly 40 m at the Sanriku coast [e.g., Mori et al., 2012], and the maximum inundation distance from the coast exceeded 5 km on both the Ishinomaki and Sendai plains [e.g., Nakajima and Koarai, 2011]. It is a resort town on a coastline of wooded islands and mountainous inlets; large sections of which suffered from damage due to the 2011 Tōhoku earthquake and tsunami. It was also estimated that the tsunami reached heights of up to 40.5 metres (133 ft) in Miyako in Tōhoku's Iwate Prefecture. Although both were 20 meters above sea level, the tsunami inundated them and washed people away. The 1960 Chilean tsunami struck the Sanriku coast with a height of several meters approximately 23 h after the earthquake (e.g., Committee for Field Investigation of the Chilean Tsunami of 1960, 1961), resulting in 123 casualties in the Tohoku region. The temperatures are highest on average in August, at around 23.7 °C, and lowest in January, at around -0.2 °C.[4]. In Hawaii, wharves were demolished and several houses were swept away. The Sanriku area extends northward from Sendai, passing through Iwate to Aomori as a saw-toothed coastline more than 600 km in length. The town is bordered to the north, west, and south by the Kitakami Mountains. The height of the wave was described as being several meters. The 8.5 magnitude earthquake occurred at 19: 32 local The 1994 o 1). The tsunami was also observed across the Pacific. The area has suffered from the effects of tsunami since ancient times, including the 869 Sanriku earthquake, and more recently during the 1896 Sanriku earthquake and the 1933 Sanriku earthquake. Tourists can freely tour the school. The average annual rainfall is 1217 mm with September as the wettest month. It is known that great Sanriku tsunamis sometimes hit the Sendai Plain in the north part of the Honshu Island in Japan. [10], The 2010 Chile earthquake caused a 1.3-metre (4.3 ft) tsunami in Minamisanriku.[11].

Among those great tsunamis, the field investigation had been rarely carried out about the tsunami of July 13th, 869 (11th year of the Jogan Era) because of the lack of the materials of old documents. This height is deemed the record in Japan historically, as of reporting date, that exceeds 38.2 metres (125 ft) from the 1896 Meiji-Sanriku earthquake. She was credited with saving many lives.
