A new paper states that 44 thousand year old things like ropes and remains of tuna, found on the Philippine's Ilin Island, suggest that the people were skilled seafarers and deep-sea fishers who did not arrive on the islands by happenstance on bamboo rafts but as intentional explorers in actual boats.
Press release by the researchers' university:

Now, given how many known volcanoes there are, wouldn't it be likely that some kind of Philippine Pompeji could be found if one follows clues as to where pre-historic people might have favoured to settle?

Below is a GoogleEarth map of South East Asia, with Smithsonian's locations of #volcano sites volcano.si.edu/ge/PlacemarkLin

The red marker in the centre-right indicates Ilin Island where the archeologists did their field research.

And if they were so used to fishing, boating, maybe sailing, could they have survived a 17 thousand km trip to South America, too? ^^ With a few stopovers? What would they have done for drinking water on their island hopping?

Screenshot from Google Earth showing land and ocean in South East Asia. Also shows markers for volcanos and a marker for the Philippine's Ilin Island. Multiple volcanoes are on almost every island and many on mainland South East Asis.

Samples obtained by #China's #Change6 #spacecraft show #moon's ancient #volcanism
Researchers said the soil brought back from the Chang'e-6 landing site contained fragments of volcanic rock - #basalt - dating to 4.2 billion years ago and to 2.8 billion years ago. This points to a long period of volcanic activity - at least 1.4 billion years - on the far side during the first half of the moon's history, when it was a more dynamic world than it is today.

Cool webstory by Reuters about future Iceland's and global volcanic eruptions to be triggered by retreating glaciers, when the weight of the ice is no longer keeping a lid on magma chambers.
Apart from neat writing, it's with video, lotsa photos, animated charts and everything one can think of to be included in #scicomm

tldr: yes, volcanic eruptions will increase with the retreat of glaciers. #Antarctica's volcanos too. #Earthquake activity has already been picking up in Iceland since 2021, also elsewhere in the #Arctic near glaciers, and around the globe.

It has happened before when Earth crawled out of the last #iceage into the #Holocene.

I might add: it happened not only at volcanos near glaciers. Rising #sealevel has triggered near-coastal volcanos, too, whether above or below the water. IIRC, a study on Stromboli proved it.

I personally think, #HungaTonga's eruption could have been one of the first submarine volcanos to have been triggered by #climateChange Another submarine volcano erupted near Japan in 2021 or 2022, forgot its name, starts with an O...
Not as huge an explosion like Hunga Tonga tho.

Lava poured from a volcanic fissure near the town of Grindavík, Iceland, in spring 2024. The eruption, which began on March 16 and remained active over two weeks later, was the largest in a string of four volcanic events on the Reykjanes peninsula starting in December 2023...

Boy, I guess nobody but me remembers the #DoctorWho serial, "Inferno"...? This is NOT a good idea!

"Ironically, enhanced geothermal uses similar fracking techniques currently used to extract oil and gas, which must be phased out if the world is to avoid climate disaster. In the geothermal version of fracking, fluid is injected deep underground, causing fractures to open up, with the liquid becoming hot as it circulates. The hot water is then pumped to the surface, where it can generate electricity for the grid."
