Damaging M7.4 subduction earthquake shakes Mindanao, Philippines The Philippines' second deadly earthquake in two weeks

A M7.4 earthquake struck the Philippine subduction zone today, causing damaging shaking across much of Mindanao. Several people have died.

This is the Philippines' second deadly earthquake in two weeks. Are the events related? And how does this quake compare to the nearby M7.6 in 2023?

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

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."

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

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.

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. ⚒️ 🧪

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.

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.
