Never knew i live about ~280 kilometers (about ~173 miles) from a volcano that only seem to have violently erupted about 13000 years ago.
Like most people in Western Europe, we deem ourselves relatively save and unfamiliar when it comes to "recent" volcano eruptions.

The Laacher See in germany.

Small excerpt from text :
"
The Laacher See lake is the largest lake in the federal state of Rhineland-Palatinate and is a popular day trip destination. During the summer, visitors can take a cool dip in the waters, while on the eastern shore of the lake, there is something exciting waiting to be discovered. There, small bubbles rise in the water. These “mofettes” are rising carbon dioxide and reflect the volcanic history of the lake (although the lake is not a maar like the other volcanic lakes in the Eifel).
About 13,000 years ago, there were several violent eruptions of the Laacher See volcano. First, rising magma came into contact with aquiferous layers and triggered an explosion of water steam. In the following eruption phase, in a similar way to Vesuvius, several ash columns formed, the ash from which was spread widely across Europe.

As mentioned above about the Laacher See, it seems that there is unusual seismic activity going on for a few years now.

However, from the text that i can find, the discoveries are partially based on the finding of gasses in the water.
I am not aware of the composition of the gas.
But assume that there are methanogens and other gas producing bacteria in that lake.
This lake seems to be the right type for to hold at least methanogens.
Think for example about Lake Kivu.

Methanogens are microorganisms that belong to the Euryarchaeota of Archeobacteria and have the ability to convert inorganic organic compounds into methane and carbon dioxide.
They exist in various natural and non-natural ecosystems and are characterized by their strict anaerobic nature, slow growth rate, and dependence on simple compounds for nutrition.

Their major end product is biogas, which primarily consists of methane and carbon dioxide.

But there is also real seismic activity going on.
Anyway, read the to text yourselfs, you have manually translate to English, google translate does not work with this site (At least where i live) :

Small excerpt from (to English translated) text :

The last volcanic eruption in the region is estimated to have occurred around 11,000 years ago. Although many scientists assumed that the volcano beneath the Eifel is extinct, a handful of studies have shown that this may not be the case.
For example, the maars - another name for crater lakes - still release significant amounts of gases that some researchers believe originate from the Earth's mantle - the geological layer just below the Earth's crust.
A study published last year also found evidence of volcanic activity. For example, the scientists discovered small earthquakes under the Laacher See, the largest crater lake in the region, not far from Koblenz.
According to the authors, this could be explained by movements of fluid, possibly magma, in the lower parts of the Earth's crust.
"If you connect the dots, it seems clear that something is brewing in the heart of northwestern Europe," said Corné Kreemer, lead author of the study and professor at the University of Nevada, from the Netherlands, in a statement.

Mantle plume
The discoveries could possibly be explained by a mantle plume exerting pressure on the Earth's surface from below. Mantle plumes are a theoretical upward flow of hot, solid rock from the Earth's mantle to the Earth's surface.
Geologists suspect that these mantle plumes are responsible for volcanic hotspots such as Hawaii.
Many seismologists believe that there is a mantle plume directly beneath Eifel Volcano that extends to a depth of more than 400 kilometers and was probably responsible for volcanic activity in the region.
Whether that plume is still active is a matter of debate, but Kreemer and his colleagues suspect that it is.

Don't panic
In the long term, it is possible that more volcanic activity will be observed in this part of Europe, although according to the researchers this does not mean that we should expect a volcanic eruption or earthquake soon - or even ever.

I remember helping my dad when he tore off our old asbestos siding to put up vinyl. Good times!

The standard Civil War dead gravestones weren't widely deployed until ~1875, ten years after the war ended. The production of gravestones on the massive scale needed to mark Civil War graves had to wait on the development of sandblasting techniques for the lettering.

Construction of the Beauvais Cathedral was started in 1225 but the cathedral has never been completed. Most fortuitously for the locals, the part where the congregation would have been expected to stand was never started, leaving just the priestly areas, a solid excuse to skip mass for almost 800 years.

Always marvel at stuff in these contracts. Easily 80% of the food goes untouched.

A crockpot but nothing to cook in it? Picky about booze brands but no specified tea brand?
The crock pot is for the Campbell's soup, to warm up his throat according to something I read while verifying this post.

It's not a strange list at all compared to others I've seen of rock and movie stars for their dressing room demands. But yeah, a lot of stuff there.

A Chinese emperor around 100bc sent an expedition out to get breeding stock of these so that they would have cavalry capable of holding their own against the precursors of the mongol tribes (most of their horses at the time where quite small almost like ponies)
