(Tweet 1/3) Ever notice that there are different types of EQ mag reported? You'll often see Ml (local mag) for local EQs <3.5, Mw (moment mag) for >3.5, and sometimes Mlr (local reduced) for a preliminary >3.5 mag, while we wait for an Mw to be calculated. #mscales" target="_blank" rel="nofollow noopener">scsn.org/index.php/educ…
