In seismology, a tsunami earthquake is an earthquake which triggers a tsunami of significantly greater magnitude, as measured by shorter-period seismic waves. The term was introduced by Japanese seismologist Hiroo Kanamori in 1972. [1] Such events are a result of relatively slow rupture velocities. They are particularly dangerous as a large ...
Severe shaking from this earthquake was recorded from the Bōsō Peninsula in the northeast to the Kii Peninsula in the southwest. A tsunami was recorded in Suruga Bay and at Kamakura, where it destroyed the building housing the statue of the Great Buddha at Kōtoku-in, [9] although the statue itself survived and has remained outdoors ever since.
The subduction zone is associated with at least two known ~9.0 M w earthquakes in the pre-instrumental period; 1737 and 1841. [6] The 1737 earthquake measured M w 9.0–9.3, and generated the largest known tsunami (60 meters) on the peninsula. [7] Another M w 9.0 earthquake struck the peninsula on May 17, 1841. It generated a tsunami up to 15 ...
A tsunami, likely triggered by an undersea landslide located 60–70 km (37–43 mi) off the coast of Jiwani, was recorded by tide gauges in countries surrounding the Arabian Sea. A tide gauge in Qurayyat, Oman, recorded a 1.09 m (3 ft 7 in) tsunami wave, the highest tsunami observation, and in Muscat, the tsunami measured 0.51 m (1 ft 8 in ...
The 1953 Suva earthquake occurred on 14 September at 00:26 UTC near Suva, Fiji, just off the southeast shore of Viti Levu. This earthquake had an estimated magnitude of M s 6.8 and M w 6.4. [1] [3] The earthquake triggered a coral reef platform collapse and a submarine landslide that caused a tsunami. [4] [5] Eight people were reported killed. [6]
The tsunami crossed the Pacific Ocean and damaged the harbor at Crescent City, California. Post-tsunami surveys indicate that the local tsunami in the central Kuril Islands reached runups of 21.9 metres (72 ft) or higher. [4] [5] This earthquake is also considered a doublet of the 2007 Kuril Islands earthquake that hit the same area on January ...
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, Japan. The magnitude of the earthquake was 8.1 M s. [1] [3] It triggered a devastating tsunami. A description of this event in an official diary from 1612 is probably the first ...
The 2007 Kuril Islands earthquake occurred east of the Kuril Islands on 13 January at 1:23 p.m. . The shock had a moment magnitude of 8.1 and a maximum Mercalli intensity of VI ( Strong ). A non-destructive tsunami was generated, with maximum wave amplitudes of 0.32 meters (1 ft 1 in).
