A year ago today a M7.0 earthquake occurred off the coast of Cape Mendocino, rattling residents and damaging homes.

False Earthquake Alert Likely Triggered by ‘Something Out in the Field,’ USGS Says | KQED
The USGS, which said at least four seismic stations detected ground motion that signaled a quake, quickly canceled the warning that startled the Bay Area.

Seismic networks make (and log, permanently) many, many more detections than ever show up as located earthquakes.
They are triggered by:
Local noise.
Small, real earthquakes very cloae to 1 station.
Teleseismic distance earthquakes triggering every station near instantly.
Sensor errors.

Like thousands of people in Northern CA, I received the earthquake early warning false alert. While these alerts can be annoying, or even scary, false alerts can be useful. During the moments after the alert came in I was able to:
- Consider & take protective action like “drop, cover, hold on” 1/3
- Consider & take protective action like “drop, cover, hold on” 1/3

I want to clarify a few points.
First, there was no earthquake or significant ground motion near Reno. Here is the recording from a seismic station nearby. The purple dot is the time that the false alert was issued. Nothing. No ground motion.

We are still waiting for information regarding what caused the false Earthquake Early Warning (EEW) alert that went out to CA and NV this morning.
While we’re waiting it’s worth mentioning that there is a trade-off between speed and accuracy and when it comes to earthquakes, seconds matter. 1/

There was an earthquake alert that went out this morning for a M5.9 near Reno, NV. This was a false alarm. There was no earthquake.
The USGS is working to identify the issue.
More soon.

Last night, for the 1st time in my life, I dreamt I was in a big earthquake.
Honestly it’s kind of strange that I haven’t dreamt about that before.

Did you know that Serpentinite is California’s state rock? Serpentinite is green to black & is often mottled with light & dark colored areas. It’s mainly found in central & northern California in the Coast Ranges, Klamath Mountains & Sierra Nevada foothills. www.conservation.ca.gov/cgs/Document...

Did you know that scientist don’t really use the Richter scale anymore? The most common magnitude scale used these days is called the “Moment Magnitude” scale. Here’s more info 🧪

Did you know that Benitoite is the California state gem? Benitoite can occur in rich blue crystals that are as striking and flawless as the finest sapphires. Gem quality benitoite is found only in a small area of San Benito County, California. 🧪 ⚒️
