Abstract

Body wave (MB ) and local magnitude (ML) were determined
for earthquakes occurring within the epicentral range of 2 to 10°
f r om New Delhi during the years 1965-1974. The following relationships
between t h em were found to hold good.
M l = (0.95 ± 1.4) + (0.81 ± 0.06) M B (A = 2» to 5°)
ML = (1.26 ± 0.76) + (0.76 ± 0.02) M B (A = 5° to 10°)
ML = (1-00 ± 0.57) + (0.80 ± 0.01) M B (A = 2° to 10»)
The regional variation of ( MCGS — -MB) has been discussed in terms
of the focal mechanism and other parameters. It has been found t h at
(MCGS— MB) is positive near India-Nepal and Tibet border while elsewhere
it is generally negative.
