Just FYI there’s already a long-standing plan in place to test the same earthquake alert system tomorrow. Hopefully millions of people aren’t just about to have a very jaded reaction to the system being fired for no major quake two days in a row, even though that’s only an unfortunate coincidence. There may be no way to avoid exactly that happening, unless they reschedule tomorrow’s test.
Seems like we can call today’s a success and skip it.
Centered in Isleton, pretty far from SF. I’m much closer and felt it.
Same here. Alert says estimated 5.7 quake in Sacramento delta area.
It was later recorded as 4.4, but that initial high reading is likely why the alert went out so broadly.
Exactly: i was reading more details provided by the USGS and the alert system, and apparently magnitude 5 is the current cutoff. They are exploring options such as including location or timing guesses in the alerts and they’re taking input on this.
Edit: if you follow this USGS link and fill out a brief anonymous report about where you were and whether you felt anything, toward the end there’s a place you can click to open optional additional questions about how the alert reached you, whether you found the alert helpful, and what ways you might like to see future earthquake alerts improved or contain more information. Also whether you feel they should be sent for a lower or higher minimum magnitude threshold.
