Still raining in Turlock. We’re just over 1.5” since Saturday night and the AR doesn’t seem to be budging at the moment. #cawx. Started out getting wrap around rain from east (uncommon) and now from north.

Greenhouse gas data is finally rolling in again, and my dashboard is back up-to-date. Unfortunately, the story hasn’t changed... 📈 More climate change indicator graphics at zacklabe.com/climate-chan...

A few of the clouds lit up beautifully at sunset after the rains this afternoon. The official Anza-Borrego Desert State Park weather station storm total was 0.81" for today (Photos: Sicco Rood).

New contender for the worst ever disaster TV show! I'm only on S1E1, but it's about Mauna Kea, located in Oahu, erupting. They figured it out from ground observations in the tropical forest ~80 miles north. The complex topography looks similar to the Alps, complicating where to drop the bombs. 🌋

This was a hilarious joke.

Ever wonder how GPS can pinpoint your location so accurately? In a recent episode of Geology Bites, MIT’s Tom Herring discusses exciting new developments in high-precision geodesy. Listen now: geosociety.co/43GicoX #Geodesy #GPS #GeosciencePodcast #GeologtBites

I was up early today for a quick interview on The Weather Channel to talk about the potential for debris flows in Southern California. A debris flow is a fast moving mixture of water, rock, soil, and even trees and boulders. Debris flows can damage structures, bury roads, and clog streams.

Number ones only, apparently.

A tale of two years at the Ione clay mine pits with @geotripper.bsky.social’s MJC geology field trip of the Central Motherlode. We are using our imagination this morning, LOL.

Good news!! The deadline to apply for this job has been extended to November 24. 🗓️ Get your applications in soon!

BREAKING: In AAUP et al v. Trump (wall-to-wall union lawsuit challenging the administration’s unlawful use of TItle VI to reshape the University of California system), the faculty and staff of the UC system WON!!! We were granted our preliminary injunction! @aaup.org

Okay, I did manage to get this blog post out before the (4pm PT!) livestream! 👀 There will be a considerable flood threat this weekend in some parts of SoCal as near-record moist airmass combines with other factors. Strong t-storms also possible. #CAwx

Super fun episode of Water Talk out today! Whether you like them fresh or canned, cranberries are both well-loved and mysterious. Leslie Holland and Amaya Atucha, UW Madison, tell us about cranberry bogs v marshes and why cranberries float. Bonus: recipes! www.watertalkpodcast.com/episodes/epi...

Oh wow @reuters.com got the photo here:

Jim Ryan's letter is not just surreal and troubling; it provides a series of deeply sobering lessons—about the perils facing public universities today; about what it means to "work with" this Department of Justice; & about what leadership does (and doesn't) entail at this especially fraught moment.

Tonight, the Groningen region in the Netherlands was shaken by a magnitude 3.4 #earthquake, according to KNMI. This is the biggest eq in the region in the past 6 years. Here's the seismogram from my Raspishake in Herne, Germany, 211 km away from the epicenter. 🧪⚒️ #Geology @raspishake.bsky.social

Happy Friday’s Eve from Jasper.

McGee Creek Camp is on of our favorite, less-developed sites on the east side of the Sierra.

Downsloping winds associated with our storm are fanning a large fire (3400+ acres) down the moraine-lined McGee Creek Canyon just south of Convict lake. Perimeter shows the campground may have been hit again. Hope the aspens there survived and the RV park is ok. share.watchduty.org/i/69510?ts=1...

Love seeing this special issue and reading about the progress and challenges in volcano hazards and mitigation in Colombia, mostly by Colombian scientists, inc. Dr. Martha Calvache. She is not only an authority on Andean volcanoes, but also a huge inspiration to (female) Colombian geologists 🇨🇴🌋👩‍🔬

A Black Hawk helicopter. SWAT teams repelling to the roof. 300 agents. Flash-bang grenades. A TV crew. “It’s 20,000 of them running through my house like we got Saddam Hussein in the closet." For all that, fed prosecutors filed no criminal charges against anyone who was arrested. Stunning report.

M 3.6 earthquake 4 km S of Vallejo, CA Did you feel it? Report it! earthquake.usgs.gov/earthquakes/...

Job alert!!! My department (Geology at @wwu.edu ) is searching for a hydrogeologist at the assistant professor level (tenure track). Fabulous colleagues and students (undergrad and master's level), spectacular setting. Ping me with questions. hr.wwu.edu/careers-facu...

Banning Obi Kaufmann books now?? This is the dumbest timeline. www.sfgate.com/national-par...

Did not feel, but my @raspishake.bsky.social did!

Earth's magnetosphere helps shields the planet from solar wind. At high latitudes, incoming particles can enter the atmosphere and produce the aurora. Stronger solar events can create short-lived disturbances that induce geoelectric fields in the ground.

The current issue of Nature Geoscience is focussed on the 1985 eruption of Nevado del Ruiz in Colombia. The lahars from this eruption destroyed a town and killed ~20,000 people only ~50 miles from where my mother grew up and I spent a lot of my childhood. www.nature.com/collections/...

How much carbon budget do we have left if we want to stay below 1.5˚C? Just 2 more years at current rates. It is essentially impossible to avoid global temperature rise exceeding 1.5˚C. climatelabbook.substack.com/p/the-shrink...

With current pledges, the world's on track for 2.6°C of warming in 2100 compared to preindustrial levels. 10 years ago, before the Paris agreement, it was 3.6°C 20+ years ago, we thought it would be 4-5°C So 2.6°C is better, but the problem is that climate impacts are way worse than we predicted.

Me and the birds are enjoying the rain. Already .28” in Turlock as of 715am. #cawx. Plenty more to come.

That's... not what science is. At all.

Prayers have been answered, at least for now... the Bz is pointing south in the direction needed to "switch on" auroral activity. We may see conditions improve soon if these conditions can be maintained, so start monitoring real-time data and head out during the next substorm.

I’m half tempted to book a flight from Sacramento or SFO and head to Reno just so I can see the Aurora from up high.

In honor of Carl Sagan's birthday this past weekend, here are some related books that will be available later this month for purchase to support @astrosociety.org... 🧪📚🔭

Jasper is solar powered, I think.

Come on over to Geoscience Bluesky and we will patiently explain all the ancient secrets of Deep Time and how to see the the traces of immense, elemental powers etched into the landscape. You will see things in new ways. You will stare at road cuts.

The clock is ticking on the shrinking Colorado River as Western states miss a key deadline "There’s no agreement yet, but time marches on, and conditions on the river continue to be problematic — more problematic over time as those reservoirs decline.” www.latimes.com/environment/...

The X5.1 CME has impacted Earth with a strength of around 37 nT. This is a strong impact, but the Bz remains positive. It is possible we see the Bz turn south, so don't get upset about this. Conditions can quickly pivot during events, especially in the beginning of a CME passage.

Remember to support local news. And ask officials what they are doing with all that dynamite. Otherwise we might be blissfully unaware of stuff like this.

⚡️Solar storm incoming! We are actively monitoring severe space weather events, occurring on 11-12 November. Severely disturbed geomagnetic conditions are expected to persist for at least 24 to 48 hours. 🔗 www.esa.int/Space_Safety... @operations.esa.int @science.esa.int

It’s been a crazy busy semester, but I’m cranking up production of my LiDAR-derived, 3D-printed volcano tissue box covers for the holidays. I hope to have a massive offering (50+) sometime near Thanksgiving. Here’s a sneak peak Will also have Etna and Stromboli! Etsy link in my profile.

NOAA cut funding to the Alaska Earthquake Center, directed by my friend Mike West. As a result, seismic monitoring by nine stations in Alaska tracking tsunami-causing earthquakes will go offline by the end of the month. This endangers people in Alaska, Hawaiʻi, and other parts of the Pacific.

I might have taken a few aurora photos.

Here's the two best shots I got of the #aurora this evening in Northern Nevada at N39° W118°. First was just north on US 95 at 05:52PM. Second was at Soda Lake at 08:40PM Both set at ISO 1600 and exposure 10s.

I love mine 😊

Fly along the San Andreas Fault in Southern California from the Cajon pass to Palmdale. Faults are rarely one single fault strand; they are often broad areas of deformation called fault zones. Lots of critical infrastructure like highways, powerlines, and railroads cross the San Andreas Fault.

If you’re enjoying the #aurora tonight and want to teach your students about how some of them form check out this lesson I developed along with physicist Jim Schroeder for @scifri.bsky.social . 🍎 🎢⚒️ www.sciencefriday.com/educational-...
