In contrast to the commonly determined short-period P-wave magnitude mb that already saturates at values between about 6 and 7, mB yields reliable magnitude estimates up to magnitudes of about 8 (Abe 1981; Kanamori 1983; Bormann and Saul 2008). Since Gutenberg proposed to measure the maximum ratio of displacement amplitude A divided by its period T, mB is related to ground motion velocity and...
