M8.8 earthquake strikes offshore Kamchatka A dangerous subduction megathrust ruptures once again

⚒️ 🧪

A M8.8 earthquake just ruptured the subduction zone offshore Russia’s Kamchatka peninsula. This is one of the world’s truly huge earthquakes, and a triggered tsunami is currently traveling across the Pacific ocean.

This same fault ruptured on July 20th in a M7.4, and last August in a M7.1.

This is a superb illustration of seismic waves travelling around the earth.

Seismic Alert - 30 July 2025 - Offshore Kamchatka

Scotland’s signs are delivering. Y’all understood the assignment. 😂

#MSH45 | July 22, 1980 | 5:14 p.m.
After 39 days of quiet, the clock resets.

At 5:14 p.m., a beige-gray column of ash punches skyward from Mount St. Helens—the first eruption visible in daylight since May 18.

Two more pulses follow at 6:25 and 7:01. At peak, ash tops 59,000 feet. It's a big show.

The monitoring station on Mauna Loa provides the longest direct measurements of CO2 in the atmosphere.
Trump wants to shut it down, which is like taking the batteries out of your screaming smoke alarm and pretending the house isn't on fire. #climatechange

A piece of red marble on the floor surrounded by gray and white marble lines. On it there are round white rudist fossil features.

Everyone else: "This is the Holy Door of St Peter's Basilica of Rome, opened by The Pope only once in 25 years in jubilee"🤩
Me: "See these lovely rudists in front of a portal in St Peter's Basilica which people call holy door"🧐

JOIDES Resolution

Surprised & delighted to see JOIDES Resolution in Kristiansand, Norway where we visited today. She & the scientists on board have made huge contributions to our science over many years. One of many projects which made the USA a world leader in science. Now being trashed by ignorance and greed.

Day 3 of the University of Derby #GeoEnergy MSc field trip sees a focus on the #CriticalMinerals needed for the #EnergyTransition.

Elon Musk survives as fellow of Royal Society despite anger among scientists Questions remain over whether further action will be taken after resignations and calls for the Tesla CEO to be expelled

Are you serious @royalsociety.org?? He is trying to destroy science, spreading dangerous misinformation, inciting violence & your response is to do nothing?

So what’s your purpose then? What do you exist for? Other than being elite?

No second state visit for Trump This is UNBELIEVABLE. Keir Starmer has just handed Donald Trump a letter from King Charles, inviting him for a second state visit to the UK. It’s totally unprecedented, and I was so outraged when I he...

Unbelievable. Donald Trump has been invited to a state visit to the UK. We should not be rolling out the red carpet to celebrate this man. Agree? Add your name to the petition today: you.38degrees.org.uk/petitions/no...

Public lands in the USA are the highlight for millions of domestic and foreign visitors. Is the aim to destroy the tourist industry as well as biodiversity?

MSc students Nat and Mat are looking rather smug about being part of our exciting new campus based #EarthSciences project at the University of Derby. More will be revealed in the near future.

A view of the long barn at Harmondsworth which was built to store grain in the fifteenth century.

The foundations of the barn are constructed from coursed rubble masonry which is predominantly composed of large (up to 79 cm long) blocks of ferricrete. Flint is also used.

Detail of the geological appearance of ferricrete with my finger for scale. The stone is composed of a rough breccia of flint stained a rusty red colour. The Ferricrete in this case is an iron-cemented flint breccia of Pleistocene to Holocene age. Read full details in the document in the link in the post.

Ferricrete is one of London’s least known building stones but it was important in the Medieval Period. Harmondsworth Great Barn (1426) is a rare secular use. This building will be demolished or moved if the Heathrow 3rd runway goes ahead … londongeopartnership.org.uk/wp/wp-conten... #urbangeology

Scientists fight Norway’s language law, warning of talent exodus Mandatory language courses for foreign researchers could harm Norway’s ability to attract the best talent, Nobel laureate says, as rule prompts legal challenge.

As a geology postdoc in Norway in 20C, I attended free, non-compulsory language classes, & still have a reasonable grasp. It made my time in Norway much richer. Imho anyone travelling for research should make the effort to learn the basics of the language. www.nature.com/articles/d41...

The purge hit the USGS today. I took the day off, but to the best of my knowledge I survived this round. At least one of my coworkers wasn’t so lucky. A bunch of incredible scientists working on what in many instances is life saving work are now out of a job due to political animus.

The 50501 Movement has planned protests at all 50 state capitols and the U.S. Capitol on Presidents’ Day at noon. While mainstream media isn’t covering it, many YouTubers have stepped up to provide coverage.

The seismic swarm in Greece gets more complicated New data reveal unexpected volcano-tectonic interactions

🧪⚒️

The seismic swarm in Greece continues - and GPS stations on Santorini show that the island itself is deforming, signaling likely movement of magma deep in the crust. In our latest post, we explore a new detailed seismic catalog and come up with a possible interpretation.

Yesterday, #PEVOLCA (Canary Islands Volcanic Emergency Plan) scientists issued a press release about changes in activity at Teide, although there are currently no signs of eruption.

What does the press release say? What does it mean for you?

Simple map of "popular" Iceland volcanoes

Thread time! We've had a lot happen geologically here in Iceland the past few weeks, and I thought to do a little explainer of what's hot in Iceland volcanoes now 🌋

1. The current power players: Fagradalsfjall & Svartsengi
2. The usual suspects: Bárðarbunga & Grímsvötn
3. The New Girl: Ljósufjöll
