npub10fmsw3ukhmqnnsjmalfekl6j4cucxvfl50he9dmqcna36a99nf6s8zx0qg (npub10fm…x0qg) USGS representative said that the automatic 5.7 estimate was sent out as an alert within eight seconds, which is impressively rapid -- but it took a figurative minute to get the better estimate of 4.1. Epicenter near Rio Vista, not that far east of Concord ("Sacramento County" sounded like it was further away than that)
4.1 might wake you up if it were a 4.1 as measured where you are...just not when it's far away.
BTW Some percentage of the time a small quake presages a larger quake coming up within minutes to days, but that is still beyond the state of the art to predict.
Usually it seems to me that multiple quakes around the Ring of Fire is a decent indication of still more quakes along the Ring coming up, but that's just me eyeballing it, apparently not good enough for the algorithms.
