full_context: Document 1: 1983 Sea of Japan earthquake: The 1983 Sea of Japan earthquake or 1983 Nihonkai-Chubu earthquake occurred on May 26, at 11:59:57 local time (02:59:59.6 UTC), It had a magnitude of 7.8 on the moment magnitude scale. It occurred in the Sea of Japan, about 100 km west of the coast of Noshiro in Akita Prefecture, Japan. Out of the 104 fatalities, all but four were killed by the resulting tsunami, which struck communities along the coast, especially Aomori and Akita Prefectures and the east coast of Noto Peninsula. Images of the tsunami hitting the fishing harbor of Wajima on Noto Peninsula was broadcast on TV. The waves exceeded 10 m in some areas. Three of the fatalities were along the east coast of South Korea (whether North Korea was affected is not known). The tsunami also hit Okushiri Island, the site of a more deadly tsunami 10 years later.
Document 2: April 2011 Miyagi earthquake: The April 2011 Miyagi earthquake (Japanese: "2011 Miyagi Prefecture earthquake" (2011年 宮城県沖地震 , 2011-Nen Miyagi-ken-oki jishin ) ) was a magnitude 7.1 M earthquake, with an epicentre off the coast of Miyagi Prefecture, approximately 66 km east of Sendai, Japan. The earthquake was classified as an aftershock of the March 11 Tōhoku earthquake, and occurred at 23:32 JST (14:32 UTC) on Thursday, 7 April 2011.
Document 3: List of earthquakes in 1938: This is a list of earthquakes in 1938. Only magnitude 6.0 or greater earthquakes appear on the list. Lower magnitude events are included if they have caused death, injury or damage. Events which occurred in remote areas will be excluded from the list as they wouldn't have generated significant media interest. All dates are listed according to UTC time. This was once again a very busy year with 22 events reaching 7.0+. Topping the list was a huge quake which struck the Banda Sea, Indonesia in February. At a magnitude of 8.5 this was one of the largest earthquakes of all time. Despite the large size no deaths were reported. Considering the array of large events, the death toll for the year was only 296. Turkey saw the majority of the deaths due to a 6.6 magnitude event in April. November 1938 saw a series of large quakes strike off the east coast of Honshu, Japan. Also in November was a magnitude 8.3 which struck Alaska. Generally Indonesia and Japan saw most of the large 7.0+ events.
Document 4: 2006 Pangandaran earthquake and tsunami: The 2006 Pangandaran earthquake and tsunami occurred on July 17 at along a subduction zone off the coast of west and central Java, a large and densely populated island in the Indonesian archipelago. The shock had a moment magnitude of 7.7 and a maximum perceived intensity of IV ("Light") in Jakarta, the capital and largest city of Indonesia. There were no direct effects of the earthquake's shaking due to its low intensity, and the large loss of life from the event was due to the resulting tsunami, which inundated a 300 km portion of the Java coast that had been unaffected by the earlier 2004 Indian Ocean earthquake and tsunami that was off the coast of Sumatra. The July 2006 earthquake was also centered in the Indian Ocean, 180 km from the coast of Java, and had a duration of more than three minutes.
Document 5: Ehime Maru and USS Greeneville collision: The "Ehime Maru" and USS "Greeneville" collision was a ship collision between the United States Navy (USN) "Los Angeles"-class submarine USS "Greeneville" (SSN-772) and the Japanese-fishery high-school training ship "Ehime Maru" (えひめ丸) from Ehime Prefecture on 9 February 2001, about 9 nmi off the south coast of Oahu, Hawaii, United States. In a demonstration for some VIP civilian visitors, "Greeneville" performed an emergency ballast-blow surfacing maneuver. As the submarine shot to the surface, she struck "Ehime Maru". Within 10 minutes of the collision, "Ehime Maru" sank. Nine of the people on board were killed: four high-school students, two teachers, and three crewmembers.
Document 6: 2011 Tōhoku earthquake and tsunami: The 2011 earthquake off the Pacific coast of Tōhoku (東北地方太平洋沖地震 , Tōhoku-chihō Taiheiyō Oki Jishin ) was a magnitude 9.0–9.1 (M) undersea megathrust earthquake off the coast of Japan that occurred at 14:46 JST (05:46 UTC) on Friday 11 March 2011, with the epicentre approximately 70 km east of the Oshika Peninsula of Tōhoku and the hypocenter at an underwater depth of approximately 29 km . The earthquake is often referred to in Japan as the Great East Japan Earthquake (東日本大震災 , Higashi nihon daishinsai ) and is also known as the 2011 Tōhoku earthquake, and the 3.11 earthquake. It was the most powerful earthquake ever recorded in Japan, and the fourth most powerful earthquake in the world since modern record-keeping began in 1900. The earthquake triggered powerful tsunami waves that reached heights of up to 40.5 m in Miyako in Tōhoku's Iwate Prefecture, and which, in the Sendai area, traveled up to 10 km inland. The earthquake moved Honshu (the main island of Japan) 2.4 m east, shifted the Earth on its axis by estimates of between 10 cm and 25 cm , and generated infrasound waves detected in perturbations of the low-orbiting GOCE satellite.
Document 7: MV Vinalines Queen: MV Vinalines Queen was a bulk carrier of the Vietnam National Shipping Lines, or Vinalines. On its last voyage the ship was travelling from Indonesia to China with more than 54,000 tonnes of nickel ore. The ship disappeared on 25 December 2011 and its fate was initially unknown. On 30 December 2011 a single survivor of its 23-member crew, Dau Ngoc Hung, was found by the British ship "London Courage", after floating with a rescue vest for 5 days. He reported that the ship sank quickly in the early hours of the morning after capsizing to the left. It sank after passing the island of Luzon in very bad weather conditions in waters up to 5000 m deep.
Document 8: Natori River: The Natori River is a river in the northeastern part of Japan. The river's headwaters start in the Zao Mountain range, it flows through the Sendai Plain and ends by draining into Sendai Bay. The river's estuary is located on Japan's east coast, and faces the Pacific Ocean. The river's flow is the greatest during the snow melt season from MarchApril, the rainy season from June July and during the typhoon season from September October. The river's length is 55 km, and its tributaries are the Hirose, Masuda and Goishi Rivers. The Natori provides water for 1 million people in Sendai.
Document 9: April 2011 Fukushima earthquake: The April 2011 Fukushima earthquake (福島県浜通り地震 , Fukushima-ken Hamadōri jishin ) was a potent magnitude 6.6 M intraplate aftershock that occurred at 17:16 JST (08:16 UTC) on 11 April in the Hamadōri region of Fukushima, Japan. With a shallow focus of 13 km , the earthquake was centred inland about 36 km west of Iwaki, causing widespread strong to locally severe shaking. It was one of many aftershocks to follow the 11 March Tōhoku earthquake, and the strongest to have its epicentre located inland.
Document 10: Tsushima Maru: Tsushima Maru (対馬丸) was a Japanese passenger/cargo ship that was sunk by the submarine USS "Bowfin" during World War II, while carrying hundreds of schoolchildren from Okinawa to Kagoshima.
Document 11: Higashi Nihon Immigration Center: Higashi Nihon Immigration Center (East Japan Immigration Center aka. Ushiku Shuyojo, Ushiku Detention Center) is one of three immigration detention centers of Japan operated by Ministry of Justice and located in Ushiku, Ibaraki prefecture. It houses approximately 700 people both of males and females. It opened in 1993 for the exceeded capacity of Yokohama Immigration Detention Center. There have been claims among the human rights activists of imates being detained for lengthy periods. March 11, 2011, because of the 2011 Tōhoku earthquake and tsunami the old facility was closed.
Document 12: 2004 Indian Ocean earthquake and tsunami: The 2004 Indian Ocean earthquake occurred at 00:58:53 UTC on 26 December with the epicentre off the west coast of Sumatra, Indonesia. The shock had a moment magnitude of 9.1–9.3 and a maximum Mercalli intensity of IX ("Violent"). The undersea megathrust earthquake was caused when the Indian Plate was subducted by the Burma Plate and triggered a series of devastating tsunamis along the coasts of most landmasses bordering the Indian Ocean, killing 230,000–280,000 people in 14 countries, and inundating coastal communities with waves up to 30 m high. It was one of the deadliest natural disasters in recorded history. Indonesia was the hardest-hit country, followed by Sri Lanka, India, and Thailand.
Document 13: 2012 Chiba earthquake: The 2012 Chiba earthquake (千葉県東方沖地震 , Chiba-ken Toho-oki Jishin , lit. "Offshore Eastern Chiba Earthquake") occurred along the northeastern coast of Chiba Prefecture, Japan at 21:05 JST (12:05 UTC) on Wednesday, 14 March. Although its epicentre lay just offshore near Chōshi city, the shallow magnitude 6.1 M earthquake produced considerable shaking inland through much of the Bōsō Peninsula and lower Ibaraki Prefecture. It occurred as a result of normal faulting in a seismically quiet region, possibly in response to the magnitude 9.0 M 2011 Tōhoku earthquake.
Document 14: No.18 Kyotoku-maru: Kyotoku-maru no. 18 is a fishing trawler which was swept inland during tsunami that followed the 2011 Tōhoku earthquake and tsunami, in the city of Kesennuma, Miyagi in Japan.
Document 15: 869 Sanriku earthquake: 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). 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 tsunami caused widespread flooding of the Sendai plain, with sand deposits being found up to 4 km from the coast.
