.@fineprintgirl Only worldwide source of EQ is @USGS and it's easy to access, so probably that. Alexa doesn't describe its data source -Tsk!

.@RegLevy Good analogies and any educational approach that can use the sense of taste is more likely to be remembered.

1861-2 atmospheric river storm destroyed 1/3 of CA's taxable land: much more damage than 1857 #Tejonquake and 1906 SF quake.

#Tejonquake 1/9/1857 had ~6 hrs of foreshocks, largest M~6, at Parkfield. So warnings are issued for other M6s at Parkfield just in case

#Tejonquake 1/9/1857 described: People fled into streets; many could not stand & in terror fell to their knees & cried out "Lord have mercy"

#Tejonquake Today is 160th anniversary of SoCal's biggest historic quake, M7.8 1/9/1857 on San Andreas from Parkfield to Cajon Pass: 220 ml

.@CelticCoco No correlation of quakes with rainfall. We have seen quakes after sudden filling of a reservoir but only right at the lake

.@CruzdesdeUsa M≥5.0 quakes happen 1000 per year somewhere in the world. 3 per day. They don't change probability elsewhere

.@BlackfireKomand Phelan is only 5 miles from San Andreas. You can read about impacts at https://pubs.er.usgs.gov/publication/cir1324 …

.@fineprintgirl In last 100 yrs, 20 quakes killed 364 people in CA. Average 3.6/yr. US deaths from floods: 82, tornados: 70, hurricane: 46

.@fineprintgirl @Koneko349 Our quake risk hasn't up because of these quakes. Nothing has changed

.@Koneko349 Yep. Nobody cared about these common swarms until the Internet let everyone know they were happening.

.@OldIdea7 A quake's ability to trigger another dies off with distance squared. Empirically, we only see correlation within 10 km.

Rate of quakes in Brawley swarm has gone back below 25 quakes/hr. Half of what it was an hour ago

.@tendancer If you live in Brawley, now would be good time to put away breakables. Probably nothing big will happen, but likelihood is up
