All Eyes Are On Japan, But The West Coast Is Now Shaking As Well... [mh3sIb20WhU]
Project Nightwatch is now on Spotify: At 7:40 on Tuesday night, while the entire planet was watching Japan, a fault in Northern California that most people cannot name broke open — and then kept breaking, more than 160 times before morning. The USGS didn't file it as an isolated event. It called that magnitude 4.3 near Cloverdale the potential mainshock of a sequence, and five weeks earlier the same fault produced the largest earthquake ever recorded on it. I've been watching this structure since June, and almost nobody else has. So what is the one measurement that tells us whether Tuesday night was the end of something — or the start of it? 🌙 TONIGHT'S DEBRIEF: • A magnitude 4.3 near Cloverdale, 3.5 miles down, flagged by the USGS as the potential mainshock of a sequence with more than 160 events • The Maacama fault — 9 millimeters a year of plate motion, a creep rate that makes it look harmless, and a paleoseismic record going back 1,200 years • A prominent active structure in populated Northern California that has no entry in the national database of active faults • Kumamoto, Kyushu: shindo 7, the maximum value Japan's intensity scale can express, and a warning window that closes within days • The fastest-converging plate boundary on Earth — and the segment of it that hasn't recorded a single earthquake in 30 days 👁️ WHAT WE'RE WATCHING: Three gauges on the same ocean moved inside 48 hours, and only one of them made the news. The question isn't whether Japan shook California — it's what the quiet one has been telling us the whole time, and whether the aftershocks east of Cloverdale stay where they are or start moving toward something much larger. 📡 STAY ON WATCH: New nightly debrief every night.
