The 1771 Great Yaeyama Tsunami (also called 明和の大津波, the Great Tsunami of Meiwa) was caused by the Yaeyama Great Earthquake at about 8 A.M. on April 24, 1771, south-southeast of Ishigaki Island, part of the former Ryūkyū Kingdom and now forming part of present-day Okinawa, Japan.According to records, 8,439 persons were killed on Ishigaki Island and 2,548 on Miyako Island. The chronicles of the Ryukyu Kingdom describe at least four coastal inundation events at Ishigaki Island during the seventeenth through nineteenth centuries: the 1771 Meiwa earthquake tsunami, which killed 12,000 people; another earthquake tsunami (1687); and … Therefore, clarifying the islands’ paleotsunami history is Considered as one of the biggest Tsunami in Japan in the olden times, it wrecked havoc all across the island. ushmm.org. Most of the low-relief islands have elevations of less than 15 m (Fig. The 1771 tsunami was accompanied by ground shaking that was widely felt in the southern and middle Ryukyu Islands 10, 11, which suggests that an earthquake triggered the collapse event and generated the tsunami. Ryukyu Islands, also called Nansei Islands, Japanese Ryūkyū-Shotō, or Nansei-Shotō, Ryukyuan Okinawa, archipelago, extending some 700 miles (1,100 km) southwestward from the southern Japanese island of Kyushu to northeastern Taiwan.The archipelago defines the boundary between the East China Sea (west) and the Philippine Sea (east). The 1771 Meiwa Tsunami, which was generated on 24 April 1771, struck the Miyako-Yaeyama Islands located in the southern part of the Ryukyu Islands, Japan. The tsunami attributed probably to a large earthquake generated by a submarine thrust fault along the Ryukyu Trench. 9. "Source Fault Model of the 1771 Yaeyama Tsunami, Southern Ryukyu Islands, Japan, Inferred from Numerical Simulation." In contrast, nine tsunami have affected the area since 1644 (Watanabe 1985). The 1771 Great Yaeyama Tsunami (also called 明和の大津波, the Great Tsunami of Meiwa) was caused by the Yaeyama Great Earthquake at about 8 A.M. on April 24, 1771, south-southeast of Ishigaki Island, part of the former Ryūkyū Kingdom and now forming part of present-day Okinawa, Japan.According to records, 8,439 persons were killed on Ishigaki Island and 2,548 on Miyako Island. The Yaeyama tsunami (M 7.4), which struck the southern Ryukyu Islands of Japan, produced unusually high tsunami amplitudes on the southeastern coast of Ishigaki Island and caused significant damage, including 12,000 casualties. It was one of the most devastating tsunamis ever to hit Japan. It was one of the most devastating tsunamis ever to hit Japan. Abstract [1] The chronicles of the Ryukyu Kingdom describe at least four coastal inundation events at Ishigaki Island during the seventeenth through nineteenth centuries: the 1771 Meiwa earthquake tsunami, which killed 12,000 people; another earthquake tsunami (1687); and two events with unrecorded causes (1625 and 1714). The tsunami that resulted claimed a third of the population (over 12,000 lives), with reports that the waves it produced were 40 to 80 meters high (although there may have been confusion in the original measurements).

The epicenter was 260 km (162 mi) from Ishigaki Island, Japan, 400 km (249 mi) from Basco, Philippines, and 425 km (264 mi) from Hualian, Taiwan. Numerical Simulation of the 1771 Yaeyama Tsunami in the Southwestern Ryukyu Arc. Movement of reef blocks and a run-up height In 1771, according to several trustworthy historical records, a huge tsunami named the Meiwa Tsunami washed the southern part of the Ryukyu Islands killing about 12, 000 people. The 1998 Ryukyu Islands earthquake (石垣島南方沖地震, Ishigakijima nanpō-oki jishin) occurred on May 4, 1998, at 08:30 local time (UTC+9) (on May 3 at 23:30 UTC) in the Philippine Sea region with M w 7.5 (USGS) and M7.7 (JMA). Great Meiwa Tsunami" which occurred on 24th April 1771 around 24.0'N, 124.3 °E on the landward slope of the Ryukyu Trench. The event of 1771 Japan Ishigaki Earthquake induced a large tsunami with an 80-meter runup height recorded. Seafloor morphology and sediment magnetic fabric in a putative 1771 Meiwa Tsunami source region, in the southern Ryukyu Islands, southwest Japan The Meiwa Tsunami of AD 1771 is regarded as an extremely strong tsunami event causing devastating damage in Japan in historical times. Several reef boulders transported by the huge tsunami waves were found along the coast and were located at elevation about 30 meters. The 1771 Meiwa tsunami The Ryukyu Islands have been struck by several severe typhoons every year; they bring high ocean swells during the summer. The 1771 Meiwa Tsunami, which was generated on 24 April 1771, struck the Miyako-Yaeyama Islands located in the southern part of the Ryukyu Islands, Japan. The giant 1771 Yaeyama tsunami occurred in the southwestern part of the Ryukyu Arc, a region on an obliquely subducting plate boundary, which shows no direct evidence of inter-plate coupling. However, colonization was dated at 0.35 Ma , indicating that P. miyakona survived the 1771 Meiwa tsunami. The waves produced were as high as 40 to 80 meters. human factors Tsunami Ryukyu Islands Ryukyu island April 24, 1771 Japan location Science ryuku islands tsunami was in japan 1771 in a large populated area. S2), so the 1771 tsunami is expected to have killed all of the vegetation and cicadas when it swept over. Considering the limited distance between Yaeyama and Taiwan Islands, this study The tsunami recorded some 12,000 casualties in these districts. Among them, three tsunami occurred near the Miyako–Yaeyama Islands EBSCO HOST CONNECTION. Mamoru, Nakamura. Maximum inundation height of the sea water was 85m and about 12,000 people were killed in these islands according to the description of Meiwa tsunami’ (‘Meiwa’ is one of the names of the his-toric era in the Japanese dating system) attacked the south-western Ryukyu Island region (Yaeyama Islands and Miyako Islands) on 23 April 1771. The 1771 Yaeyama tsunami is successfully reproduced using a simple faulting model without submarine landslide. / flickr Potres magnitute 7,4 izazvao je snažan tsunami koji je uništio veći broj gradova u regiji, no najveća šteta zabilježena je na području Ishigaki i Miyako otočja.
