Moment magnitude and energy magnitude scales. Other magnitude scales are based on aspects of seismic waves that only indirectly and incompletely reflect the force of an earthquake, involve other factors, and are generally limited in some respect of magnitude, focal depth, or distance.
An upthrust of 6 to 8 metres (20 to 26 ft) along a 180 kilometres (110 mi) wide seabed at 60 kilometres (37 mi) offshore from the east coast of Tōhoku resulted in a major tsunami that brought destruction along the Pacific coastline of Japan's northern islands.

The Richter scale [1] ( / ˈrɪktər / ), also called the Richter magnitude scale, Richter's magnitude scale, and the Gutenberg–Richter scale, [2] is a measure of the strength of earthquakes, developed by Charles Francis Richter in collaboration with Beno Gutenberg, and presented in Richter's landmark 1935 paper, where he called it the ...
Mount Fuji (富士山, Fujisan, Japanese: [ɸɯꜜ (d)ʑisaɴ] ⓘ) is an active stratovolcano located on the Japanese island of Honshu, with a summit elevation of 3,776.24 m (12,389 ft 3 in).

The demon core (like the core used in the bombing of Nagasaki) was, when assembled, a solid 6.2-kilogram (14 lb) sphere measuring 8.9 centimeters (3.5 in) in diameter. It consisted of three parts: two plutonium-gallium hemispheres and a ring, designed to keep neutron flux from "jetting" out of the joined surface between the ...
