Body wave magnitude formula
Webbetween the body wave (m b) and surface wave (M s) magnitudes for a seismic event. Most M s formulas have been developed for teleseismic distances and for Rayleigh waves in the period range of 17–23 s. For earthquakes of small-to-intermediate magnitude and explosions recorded at regional distances, the amplitudes of Rayleigh waves in A I = < P > A. When studying light waves, power is described in Watts, and because light is so expansive, it is ...

WebSeismic waves within this range of periods can be used to compute body wave magnitude mB. Its formula is similar to local magnitude Ml, as follow: mB = log(A/T) max + Q(Δ,h) … 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 inherent in the use of surface waves. mB is based on the P- and S-waves, measured over a longer period, and … See more 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 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. It was introduced in the 1960s with the establishment of the World-Wide Standardized Seismograph Network See more 1. ^ Havskov & Ottemöller 2009, p. 17. 2. ^ Bormann, Wendt & Di Giacomo 2013, p. 37; Havskov & Ottemöller 2009, §6.5. See also Abe 1981. See more The regional mbLg scale – also denoted mb_Lg, mbLg, MLg (USGS), Mn, and mN – was developed by Nuttli (1973) for a problem the original ML scale could not handle: all of North America east of the Rocky Mountains.

WebThe equation of body wave magnitude is as follows: Mb = log (A¦T)+ + Q (h, Δ) Here A is the ground motion amplitude (in microns after removal of the instrument response), T is … WebSeismic waves within this range of periods can be used to compute body wave magnitude mB. Its formula is similar to local magnitude Ml, as follow: mB = log(A/T) max + Q(Δ,h) where A and T are body wave amplitude and period respectively that can be obtained by measuring the seismic waves. Q(Δ,h) is the distance adjustment term, related to the ...
