The earthquake moved Honshu 2.4 m (8 ft) east, shifted the Earth on its axis by estimates of between 10 and 25 cm (4 and 10 in), [65] [66] [67] increased Earth's rotational speed by 1.8 μs per day, [68] and generated infrasound waves detected in perturbations of the low-orbiting Gravity Field and Steady-State Ocean Circulation Explorer ...
In Japan, the Shindo scale is commonly used to measure earthquakes by seismic intensity instead of magnitude. This is similar to the Modified Mercalli intensity scale used in the United States, the Liedu scale used in China or the European Macroseismic Scale (EMS), meaning that the scale measures the intensity of an earthquake at a given location instead of measuring the energy an earthquake ...
The Great Hanshin Earthquake occurred on January 17, 1995, at 05:46:53 JST in the southern part of Hyōgo Prefecture, Japan, including the region known as Hanshin.It measured 6.9 on the moment magnitude scale and had a maximum intensity of 7 on the JMA Seismic Intensity Scale (XI–XII on the Modified Mercalli intensity scale).

The Japan Meteorological Agency (JMA) officially named this earthquake the 2024 Noto Peninsula earthquake (Japanese: 令和6年能登半島地震, Hepburn: Reiwa 6-nen Noto-hantō Jishin). [6] It led to Japan's first major tsunami warning since the 2011 Tōhoku earthquake , [ 7 ] and a tsunami of 7.45 m (24 ft) was measured along the Sea of ...
The geographic poles are defined by the points on the surface of Earth that are intersected by the axis of rotation. The pole shift hypothesis describes a change in location of these poles with respect to the underlying surface – a phenomenon distinct from the changes in axial orientation with respect to the plane of the ecliptic that are caused by precession and nutation, and is an ...
Anticipated area of the Tokai Earthquake Nankai, Tōnankai and Tōkai earthquake areas. The Tōkai earthquakes (Japanese: 東海地震) are major earthquakes that have occurred regularly with a return period of 100 to 150 years in the Tōkai region of Japan. The Tōkai segment has been struck by earthquakes in 1498, 1605, 1707, and 1854. [1]
The 1946 Nankai earthquake (昭和南海地震 Shōwa Nankai jishin) was a great earthquake in Nankaidō, Japan. It occurred on December 21, 1946, at 04:19 JST (December 20, 19:19 UTC). [ 1 ] The earthquake measured between 8.1 and 8.4 on the moment magnitude scale , and was felt from Northern Honshū to Kyūshū .
Following the earthquake, the Japan Meteorological Agency (JMA) issued a 'Nankai Trough Earthquake Extra Information' advisory [28] that the probability of a megathrust earthquake along the Nankai Trough increased from a 0.1% per week to 1% chance [29] in what was the first advisory of its kind but clarified that it was not imminent.
