A big aftershock (Mw 6.9) of the magnitude 7.4 #earthquake that happened today offshore Mindanao, Philippines. Same mechanism, roughly same depth.

"When authoritarians seize power, it is crucial to recognise courageous defenders of freedom who rise and resist."

"…rule of law abused by those in control, free media silenced, critics imprisoned, and societies pushed towards authoritarian rule and militarisation."

In addition to praising María Corina Machado action for democracy, #Nobel Committee included these powerful words in its announcement.

"We live in a world where democracy is in retreat, where authoritarian regimes are challenging norms and resorting to violence."

www.nobelprize.org/prizes/peace...

Excerpt of the Nobel announcement. It says "Democracy is a precondition for lasting peace. However, we live in a world where democracy is in retreat, where more and more authoritarian regimes are challenging norms and resorting to violence. The Venezuelan regime’s rigid hold on power and its repression of the population are not unique in the world. We see the same trends globally: rule of law abused by those in control, free media silenced, critics imprisoned, and societies pushed towards authoritarian rule and militarisation. In 2024, more elections were held than ever before, but fewer and fewer are free and fair."

Just a reminder how far-right & right-wing can promote toxicity and pose serious risks to people and society. Day after day, we see the situation becoming increasingly frightening in the US. But we are not immune in Europe.

Stay strong @mark-bray.bsky.social !

An #earthquake of magnitude Mw 7.4 struck offshore #Mindanao island, #Philippines.
Both hypocentral depth (~60km) and mechanism (thrusting) suggest a rupture on, or near the subduction #megathrust which allows the Philippines oceanic plate to plunge westward under the islands. ⚒️ 🧪

Today's editorial by @lemonde.fr 👇 is about the incompatibility of AI and decarbonization.

The incompatibility of AI and decarbonization

EDITORIAL. The notion of 'techno-solutionism,' asserting that artificial intelligence could achieve sufficient energy savings to make the process sustainable, is an illusion.

Even though everything is far from perfect in France, especially under our current president, our justice system is capable of sending a former president to prison.
It's the rule of law, stupid !

A big #earthquake a few minutes ago at Kamchatka with a magnitude of M7.8!

I guess this makes it the biggest aftershock following the M8.8 on Jul 30th. Here's the seismogram of my @raspishake.bsky.social - the seismic waves arrived about 11 mins after origin time here in Herne, Germany. 🧪⚒️ #geology

Famous names—Yellowstone, Etna, Kīlauea—draw the cameras. But the most dangerous volcanoes may be the “quiet” ones, hidden in jungles or beneath the sea, biding their time.

🌋 Excited to share my new essay in Aeon: one of the most underappreciated global risks isn’t an asteroid or supervolcano—it’s the eruptions we don’t see coming:

Aeon Magazine @aeon.co · 25d

The science of volcanoes and their relationship with the climate is hard to keep up with. Why do some volcanoes give us little warning before they blow? Are we ignoring the next big eruption?

Hidden volcanoes: are we ignoring the next big eruption? | Aeon Essays

The next global disaster may be triggered by a catastrophic eruption. How can we prepare for the fire beneath our feet?

Next survey of the volcanic and seismic activity offshore the Island of #Mayotte will happen from Sept 25th. 👇

Reminder: in 2018, a new #volcano 🌋 formed 50km east of the island 🏝️. It was the largest active submarine eruption ever documented - ⚒️

Transferring seismo-tectonic studies into hazard studies is very important, although often neglected by us, researcher in university lab.
Here is our the new paper by S. El-Kadri, our former PhD student, about seismic hazard in Lebanon and surrounding areas:

Implementation of an interconnected fault system in probabilistic seismic hazard assessment (PSHA): the Levant fault system

Abstract. The Levant fault system (LFS), a 1200 km long left-lateral strike-slip fault connecting the Red Sea to the East Anatolian fault, is a major source of seismic hazard in the Middle East. In th...
