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 ...
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 ...
The earthquake [62]) was a powerful magnitude 6.6 earthquake [63] [64] that occurred 10:13 a.m. local time (01:13 UTC) on July 16, 2007, in the northwest Niigata region of Japan. [63] Eleven deaths and at least 1,000 injuries have been reported, and 342 buildings were completely destroyed, mostly older wooden structures.
A tsunami advisory was issued after the earthquake. It covered Kōchi, Ehime, Oita, Miyazaki and Kagoshima Prefectures [20] and predicted waves of up to 1 m (3.3 ft). [21] Subsequently, tsunami waves of 50 cm (1.6 ft) were observed in Miyazaki, 30 cm (0.98 ft) in Kōchi, and 20 cm (0.66 ft) in Kagoshima. [20] The advisories were lifted at 22:00 ...
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 2011 earthquake off the Pacific coast of Tōhoku (東北地方太平洋沖地震, Tōhoku-chihō Taiheiyō Oki Jishin), or as it's sometimes called in Japan, (東日本大震災, Higashi nihon daishin-sai) [1] also known as the 2011 Tohoku earthquake, [2] the Great East Japan Earthquake, [3] [4] [fn 1] and the 3.11 Earthquake, was a ...
[2] [5] The released seismic moment of the earthquake was 1.3×10 19 Nm. This earthquake is a normal faulting intraslab event within the subducting Philippine Sea plate. [6] The slip of the earthquake was estimated to be about 1.5–2.4 meters (4 ft 11 in – 7 ft 10 in). The locations of aftershocks were distributed roughly in N–S direction. [7]
The 2015 Ogasawara earthquake was a 7.8 magnitude earthquake which struck offshore Japan 189 km (117 mi) west northwest of Chichi-jima in the Ogasawara Islands on May 30 at a depth of 664.0 km (412.6 mi). [1] The shaking of the earthquake was observed almost all over Japan, [2] as it was one of the largest deep-focus earthquakes recorded worldwide.
