OK, what came first for you? The earthquake or the app blaring, waking you up in the middle of the night?

The app for me. I want to hear about your experience last night. Looking to interview a couple of people this morning on the topic of last night's quake near Boulder Creek.

I don't think people fully appreciate how apocalyptic things are for US science. I haven't had any new funding since 2024, but I'm still ok since typical grants are for three years. This means next year I will be completely out of funding and will have to fire everyone in the lab. It's not great.

Figure from Verdon and Harris (2025) with pink star showing rough location of today’s earthquake. 
Orange polygon shows area where pressure gradient exceed 0.9 psi/ft. Grey dots show likely cases of induced seismicity.

Today’s M4.9 #earthquake in Louisiana represents an unusual earthquake for the region and occurred in the area of the Haynesville Shale, which has been associated with an increased likelihood of hydraulic fracturing induced seismicity. ⚒️🧪

I haven’t posted for a while, because I just don’t know what to say anymore…
But here are some prehistoric rock scratchings in Valcamonica that I found amazing, so maybe some of you will enjoy them too.

Photograph from 1911 taken by Herbert Ponting whilst with Scott's Antarctic Expedition

The monochrome photo is taken from within a cave. The walls of the cave are made of ice. The cave entrance is in the mid distance with two figures standing looking out towards a distant ship. Between them and the ship there is first a 'beach' of ice before the sea itself. The ship could be up to 800 metres away

What makes the photo so special is that where the figures are at the cave entrance there is a band of very white snow and ice (contrasting with the comparatively dark inside of the cave) that creates a stark framework in which the men and the ship are captured. It is made even more dramatic by the fact that the cave entrance is at least 30 metres high and is in the shape of a distorted elipse with the tail sloping off to the right at the top of the elipse

The photo being in monochrome in a largely white environment makes the photographers skill all the more laudable

This photo was taken in 1911 using glass plate technology by Herbert Ponting who was part of Scott's Antarctic expedition,

The composition and detail are exquisite with the band of white snow/ice creating a perfect frame around the two people and the ship in the distance

Iconic imo

New Year Office Chitchat
 
How was your Christmas?
you ask

and I think 
of the bloodstained rug

and the silent scraping
of the spade

in the garden
at midnight

and the wash wash
washing of my hands

and the dreams,
those endless dreams

which haunt
the night-time

and smudge
their thumbprints

on the day
to come

and I reply
Super, thanks. Yours?

This poem is dedicated to anyone heading back into work and having to endure dull conversation about what they got up to during the Christmas holidays.
