Volcano factoids

Wired says Chimborozo volcano in Ecuador had the largest eruption in the past 2000 years.

erupted last about 640 AD.

another factoid:

While the summit of Mount Everest is the highest point on the Earth above sea level, the summit of Chimborazo is the farthest place on the surface of the Earth from its exact center, a distance of 3,968 miles (6,384.4 kilometers). It’s important to remember that the Earth is not a perfect sphere but instead bulges out at its equator. Chimborazo is only one degree south of the equator, while Mount Everest is 28 degrees north. Chimborazo’s summit is 2.1 kilometers farther from the Earth’s center than Everest.

 and the wired article notes that France

the Chaîne des Puys lava domes (see below) formed at ~4040 BC, meaning they are very much still capable of another eruption. - See more at: http://www.wired.com/2014/06/volcano-world-cup-group-e/#sthash.1Qvkfos8.dpuf

between this and the Lacher See Volcano, (10000 BC) one wonders if many of the "dragon" legends are due to pre historic eruptions being put into stories of the Germanic tribes, in the same way that when Anaeis visited the "gates of hell" , he went to Cumae, located near Vesuvius.

Ulysses, however, found his "gates of hell" at the western edge of the known world,

and in the Percy Jackson series, one of the "doors of death" is at Epirus.

where the "dragon lakes" of Mt Pindos are located, but the volcanism there predates man.
