Between December 1 (12:00 AM PST) and December 7 (11:59 PM) there were 44 earthquakes in California of magnitude 2.0 or larger.
🔸40 earthquakes between magnitude 2.0 - 2.9
🔸4 earthquakes between magnitude 3.0 - 3.9
The largest earthquake was a magnitude 3.4 near Fortuna, CA.

Are we having more earthquakes than usual? Not really.
On average there are 15-18 M7+ quakes every year and ~10x that many magnitude 6-6.9 earthquakes.

There are more than 100,000 earthquakes recorded in Japan every year. This is because Japan is situated on the boundary of 4 major tectonic plates.

The seismic waves from the M7.6 earthquake in Japan are rolling under us here in Northern California - far too small to feel but not too small to be detected by seismic instruments.

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/

The USGS is working to identify the issue.
More soon.
