I totally felt this little M3.2 earthquake. So slight that I thought it was more like an animal jumping up on the couch, but the cat was already on the couch. If you felt it, you can report it here:

It’s been a gloomy day in San Francisco, so here are some pictures of some icebergs in Greenland on a similar gloomy day back in September. I prefer having icebergs around.

Brussels sprouts grow upright on a tough, woody stem. This picture is a partly mechanized harvest, but a crew of workers used machetes to cut off the stalks in the field, while another worker trims off the leaves as he feeds the stalks into the machine. It's grueling work especially when it is hot.

Are you traveling over the holiday weekend?
Be sure to check out some of California’s “Geo Gems” - notable geologic features in California state parks. These geologic wonders illustrate the legacy and continuing geologic evolution of California.

Good morning Calaveras fault! Just felt a little M4.3 earthquake that is located near Gilroy. Just slight shaking in San Francisco that interrupted me as I was sipping coffee. If you felt it, you can report it here: earthquake.usgs.gov/earthquakes/...

Greenland Part 3: One of my hopes for our trip to Greenland was to see polar bears in the wild. We only saw a mother and two cubs from a great distance on the first day. It was still amazing. Here is my best grainy photo.

More Greenland photos, featuring some geology. Scoresbysund has some fantastic exposures of columnar basalts, which are ~55 million years old (young for Greenland rocks!) related to flood basalts when the Atlantic was opening up. Fantastical shapes and fall tundra colors

I swore an oath to the Constitution in 1986. I've upheld it through 25 years of service and every day since I retired.
If Trump's trying to intimidate me, it won’t work. I’ve given too much to our country to be silenced by bullies who care more about power than the Constitution.

I’ll be sharing more photos from our September trip to Greenland in the coming weeks now that I’m catching up on photos. Get ready for more icebergs, landscapes, fluffy arctic animals, and geology from the trip.

Took a quick detour on my way home to check out the view from Yerba Buena Island as the sun was going down.

Time for more Greenland photos! I had no view of the amazing aurora borealis show this week, but got to see a decent display in September in Greenland. Ribbons of pulsating light at times. Amazing to experience.

There is a super-murder of crows flying by towards downtown San Francisco. This went on for minutes and probably involved more than a thousand crows.

NOAA cut funding for critical parts of the tsunami and earthquake detection system in Alaska, primarily in the Aleutians. I spoke to Wash Post about negative impacts. But, hey, what are the chances of a deadly tsunami being triggered in Alaska? (Gift article, not behind paywall) ⚒️ wapo.st/4qKvavQ
This lab is key for tracking deadly waves. Its sensors are about to go offline.
After NOAA cut funding to the lab that’s been monitoring seismic activity for more than 25 years, nine stations tracking tsunami-causing earthquakes for the agency will go offline by the end of the mo...

Just saw this rather large bobcat walk up to this flock of wild turkeys in the backyard. A lot of commotion, but I think the bobcat was reluctant to take on 15 turkeys at once.

In the century leading up to 1975, nearly 6000 freighters went down in the Great Lakes.
The Edmund Fitzgerald was the last.
The last. In 50 years, not a single commercial freighter has been lost in the Great Lakes.
Why?
It's NOAA. Of course it's NOAA.

Productive stay-cation day:
Made waffles for breakfast
Went for a hike to Sutro Forest
Did a bunch of yard work
Baked a loaf of bread

This weekly roundup is a good reminder that earthquakes happen everyday in California. While most are small, eventually there will be one that will be disruptive and, knowing this, it is best to be prepared.
Between November 3 (12:00 AM PST) and November 9 (11:59 PM) there were 50 earthquakes in California of magnitude 2.0 or larger.
🔸45 quakes between magnitude 2.0 - 2.9
🔸5 quakes between magnitude 3.0 - 3.9
The largest earthquake was a magnitude 3.8 near San Ramon, CA.
