WebA magnitude Mw 7.8 earthquake occurred on 25 April 2015 (referred as Gorkha earthquake). We have analyzed the spatial variation of b-value and two-dimensional strain () within Nepal Himalaya ... Body-waves consist of P-waves that are the first to arrive (see seismogram), or S-waves, or reflections of either. Body-waves travel through rock directly. See more The original "body-wave magnitude" – mB or mB (uppercase "B") – was developed by Gutenberg (1945b, 1945c) and Gutenberg & Richter (1956) to overcome the distance and magnitude limitations of the ML scale … See more The mb or mb scale (lowercase "m" and "b") is similar to mB , but uses only P-waves measured in the first few seconds on a specific model of short-period seismograph.

WebAnswer (1 of 5): Earthquake size, as measured by the Richter Scale is a well known, but not well understood, concept. The idea of a logarithmic earthquake magnitude scale was first developed by Charles Richter in the 1930's for measuring the size of earthquakes occurring in southern California us...
