List of earthquakes in Japan. Earthquakes M5.5+ around Japan (1900–2016) M7.0–7.9=163 EQs, M8.0+=14 EQs. [ 1] This is a list of earthquakes in Japan with either a magnitude greater than or equal to 7.0 or which caused significant damage or casualties. As indicated below, magnitude is measured on the Richter magnitude scale ( ML) or the ...
Coordinates: 37°25′17″N 141°1′57″E. Fukushima nuclear accident. Part of the 2011 Tōhoku earthquake and tsunami. The four damaged reactor buildings (from left: Units 4, 3, 2, and 1) on 16 March 2011. Hydrogen-air explosions in Units 1, 3, and 4 caused structural damage. [ 1]
In the Himalayan region, where the Indian Plate subducts under the Eurasian Plate, the largest recorded earthquake was the 1950 Assam–Tibet earthquake, at magnitude 8.7. It is estimated that earthquakes with magnitude 9.0 or larger are expected to occur at an interval of every 800 years, with the highest boundary being a magnitude 10, though ...
For the rest of Japan, the peak figure using the post-Fukushima standards was 4.7% immediately after the catastrophe, falling below 0.5% by mid-2012, and below 0.1% by mid-2013. [183] In February 2014, NHK reported that TEPCO was reviewing its radioactivity data, after finding much higher levels of radioactivity than was reported earlier.
Intensity 7. The Intensity 7 ( 震度7, Shindo 7) is the maximum intensity in the Japan Meteorological Agency seismic intensity scale, covering earthquakes with an instrumental intensity (計測震度) of 6.5 and up. [ 15] At Intensity 7, it becomes impossible to move at will. [ 13] The intensity was created following the 1948 Fukui earthquake.
As part of the Pacific “ring of fire," Japan is one of the world's most earthquake-prone areas. A magnitude 9.0 earthquake and subsequent tsunami in March 2011 devastated large areas along Japan ...
A seismogram recorded in Massachusetts, United States. The magnitude 9.1 (M w) undersea megathrust earthquake occurred on 11 March 2011 at 14:46 JST (05:46 UTC) in the north-western Pacific Ocean at a relatively shallow depth of 32 km (20 mi), [9] [56] with its epicenter approximately 72 km (45 mi) east of the Oshika Peninsula of Tōhoku, Japan, lasting approximately six minutes.
The following is a summary of significant earthquakes during the 21st century. In terms of fatalities, the 2004 Indian Ocean earthquake was the most destructive event with 227,898 confirmed fatalities, followed by the 2010 Haiti earthquake with about 160,000 fatalities, [ 2] the 2008 Sichuan earthquake with 87,587 fatalities, the 2005 Kashmir ...
