This paper considers seafloor deformation associated with the 1946 Nankai earthquake, which occurred in the Nankai Trough subduction zone off the coast of southwest Japan. Earthquake. ADMIN; ATLAS; USGS National Earthquake Information Center, PDE; Additional Information A fault model of the 1946 Nankaido earthquake (M=8.2) is determined by the use of tsunami records of Uwajima, Shimotsu and Hososhima which were located within or near the area of major coseismic crustal deformation. Over 70 years have passed since the most recent shakes, the 1944 Tōnankai earthquake and the 1946 Nankai earthquake. The 1946 Nankai earthquake (昭和南海地震 Shōwa Nankai jishin) was a great earthquake in Nankaidō, Japan. The 1946 Nankai earthquake (南海地震 Nankai jishin) was a great earthquake in Nankaidō, Japan. The 1946 Nankai earthquake was the most recent in a long series of great earthquakes to have occurred along the Nankai Trough subduction zone, each of which has caused damage in southwestern Japan. Earthquake []. Earthquake.

Thus, another quake is … The earthquake measured between 8.1 and 8.4 on the moment magnitude scale, and was felt from Northern Honshū to Kyūshū. (2002) shows that the two subevents of the 1946 Nankai earthquake is bounded by a tear and a subducting seamount on the Philippine Sea Plate. 1946-12-20 19:19:10 UTC Contributed by US 3 ISCGEM ; View Nearby Seismicity Time Range ± Three Weeks Search Radius 250.0 km Magnitude Range ≥ 5.0 ANSS Comcat ; For More Information. The Nankai Trough is a convergent boundary where the Philippine Sea Plate is being subducted beneath the Eurasian Plate.Large earthquakes have been recorded along this zone since the 7th century, with a recurrence time of 100 to 200 years. A fault model of the 1946 Nankaido earthquake derived from tsunami data. The earthquake measured between 8.1 and 8.4 on the moment magnitude scale, and was felt from Northern Honshū to Kyūshū. Impact Summary; Technical Summary; Contributors. It is therefore a zone of … The Nankai Trough is a convergent boundary where the Philippine Sea Plate is being subducted beneath the Eurasian Plate.Large earthquakes have been recorded along this zone since the 7th century, with a recurrence time of 100 to 200 years.

Earth Planet, Inter., 28: 32036. We perform a simple subevent analysis of seismic P-waveforms from historical records of the 1946 Nankai earthquake. The 1946 Nankai earthquake (昭和南海地震 Shōwa Nankai jishin) was a great earthquake in Nankaidō, Japan.

The following three improvements from the previous study (Satake, 1993) were made. The results of this analysis establish that the earthquake rupture consisted of two main subevents, one lying within the 1-day aftershock area off the Kii Peninsula, while the other lies much farther to the west in the area of pronounced crustal deformation of western Shikoku.

Rupture process of the 1946 Nankai earthquake estimated using seismic waveforms and geodetic data Satoko Murotani1,2, Kunihiko Shimazaki1, and Kazuki Koketsu1 1Earthquake Research Institute, University of Tokyo, Tokyo, Japan, 2Now at National Museum of Nature and Science, Tsukuba, Japan Abstract The rupture process of the 1946 Nankai earthquake (M JMA 8.0) was estimated using seismic The earthquakes occur with a return period of about 90–200 years, and often occur in pairs, where a rupture along part of the fault is followed by a rupture elsewhere, notably the 1854 Ansei-Tōkai earthquake and the 1854 Ansei-Nankai earthquake the next day, and the 1944 Tōnankai earthquake, followed by the 1946 Nankaidō earthquake. M 8.3 - 1946 Nankai Earthquake, Japan Experts believe there is a 70% to 80% probability of a severe Nankai Trough earthquake within 30 years. Location of this band is on the deeper side of the focal regions of the 1944 Tonankai and 1946 Nankai earthquakes, which represent the last series of the Nankai Trough earthquake. The easternmost segment of the Nankai trough remained unruptured during the 1944 and 1946 earthquakes that affected the rest of the trench. The Earthquake Event Page application supports most recent browsers, view supported browsers. On December 20, 1946, while Japan was recovering from all the devastation of World War II, it was hit once again with the Nankaido earthquake, a very powerful one of magnitude 8.1, along this line. For instance, Cummins et al. It occurred on December 21, 1946, at 04:19 JST (December 20, 19:19 UTC).

Coseismic slip distribution on the fault plane of the 1946 Nankai earthquake (M w 8.3) was estimated from inversion of tsunami waveforms. It occurred on December 21, 1946, at 04:19 JST (December 20, 19:19 UTC).
