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.
The area is associated with large earthquakes in 1662 (M w 7.9), 1941 (M w 8.0), 1961 (M w 7.5), [3] 1968 (M w 7.5) and two in 1996 (M w 6.6 [4] and 6.7 [5]). The Hyūga Sea is interpreted as a transition zone between the highly coupled Nankai Trough in the northeast and weakly coupled Ryukyu Trench further southwest. [6]
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 earthquake had a focal mechanism corresponding to reverse faulting. [10] A magnitude 5.6 aftershock struck the area at 21:58 JST, succeeded by another aftershock, at 23:18 JST of magnitude 4.5, along with over 50 other aftershocks hitting on Saturday, between magnitude 2 and 5. [11] [4] [12]
This is the sentence (actually its second part) I have a problem with: "The earthquake moved Honshu (the main island of Japan) 2.4 m (8 ft) east and shifted the Earth on its axis by estimates of between 10 cm (4 in) and 25 cm (10 in).[19][20][21]"
Earthquakes early Monday again struck Japan's north-central region of Ishikawa, still recovering from the destruction left by a powerful quake on Jan. 1, but the latest shaking caused no major damage.
