I find it vastly easier to believe you could get 30 kilometers of horizontal flow than 6-7 kilometers of vertical flow while crossing layers.

Ok @brandontbishop.bsky.social this paper puts the quakes at the basement interface 7-8 km, but notes that the injection wells are about 1 km deep. Thats an enormous vertical fluid migration. I can’t be reading this right am I? That literally would have the disposed fluids crossing the Eagle ford!

Yes, yes, and yes.

A School of Mud Volcano Islands in Azerbaijan - NASA Science The tadpole-shaped islands along the Absheron Peninsula were born by explosive mud volcano eruptions and reshaped by erosion.

Mud volcano islands off Azerbaijan are featured in today’s NASA Earth Observatory Image of the Day!

It was a great pleasure to contribute to this!

The village of Oia, sitting on a cliff overlooking the submerged caldera of Santorini at sunset.

During literature research on the Minoan Eruption of Santorini I came across a study arguing for the eruption’s role in the emergence of the smallpox virus. The eruption caused local climatic changes and mammal migrations, aiding the virus' evolution. Wild! 🌋🦠

Adding to what @drspacejunk.bsky.social has written:

I keep noticing how much ice has melted between 1972 and 2026.

Fast-tracking US critical minerals could backfire without safeguards, Oxfam warns A central concern is that compressing timelines could undermine the very stability the US is seeking.

I have been thinking about this lately, so it’s nice to see an article about how fast tracking mineral projects in the US may end up actually slowing or stopping projects all together as mining companies risk their “social license to operate”

Correct, and a normal El Niño event would be 1.5-2 degrees above average temperature for that region. The forecasts as of a week or two ago leaned towards a normal El Niño, these are now trending towards an unusually strong event.

It’s April 18th, so time to repost some of my great-grandfather’s photos of San Francisco after the 1906 earthquake

Turns out you actually don’t need the poles for this - twice, about 800 and 700 million years ago, we think the entire planet froze over.

Neat, thanks!

It’s fleet week here, so jets have been overhead the last couple days, but I saw this one and um, is that a U-2???

This was a tough one to write, and I took a bit of a personal risk sharing my own career-long process of discovery from tentatively swayed by the potential for deep-sea mining to convinced that we are simply not ready.

A piece of beige geyserite in my gloved hand. It's about 13cm long and has a weird convulated surface, very wrinkly like a brain. From the Natural History Museum, London's collection.

This is your brain on #minerals

Can you walk any farther to the right and aim a photo down the street? Wondering what my old apartment looks like. The buildings behind the Arco are new.

Anyone else think it is one of the dumbest, most ridiculous, most insane things ever that Perseverance's sample tubes have just been... abandoned on Mars? The science in those tubes could be revolutionary & they're just going to sit there, watching dust devils twirling across the skyline.

If this is a smaller company or college, mention it in the application letter.

If it’s something bigger expect it is getting a digital AI tool triage first, some may be trained to just recognize them, I’m not sure how to handle that. Make sure you hit as many keywords for the software as you can.

This is pretty much canonical.

Yall coulda just paid attention to Danny Farquhar.

I’m betting he’s strong on deep dish pizza and Italian beef though.

Wasn’t that literally the difference with Artemis 1?

How many birds die from wind turbines? Surprising findings Critics say wind turbines endanger birds but two new studies have now analysed the risk in more detail. What they have found could change the debate.

Two recent studies have re-examined risk of birds colliding with rotor blades of wind turbines.
Research found that there was not a single collision.
"The results from Aberdeen Bay show that modern offshore wind farms can be operated with low risk to wildlife."

If you’re looking for someone who is an award winning mineralogy instructor, I’d listen.

There are normally about 20 tankers heading to the US for this. Nearly 100 is a lot. This will take the US supply and put it towards demand in Asia and elsewhere. This means if US consumers want gas, they will be competing with people in true shortages. Reduce shortage there by creating in the us.

The astronauts working with a PTT (push to talk) button gives me some field trip nightmares!

@elakdawalla.bsky.social just said they were RCS pulses.
