It sounds like Campi Flegrei is the site of an old very large eruption, like the Valley of 10,000 Smokes left after Katmie erupted in 1911 or 12. Anyone have more information/history on CF?
And we should never underestimate the potential for volcanic disaster. In 1902 politicians insisted that Mt. Pelee was not that dangerous so that people would stay in San Pierre for an important election. It was important that they stay so a white man, not a colored, be elected to the French national assembly. Then the mountain blew killing at least 30,000 people. After several months of paying coloreds and blacks a small disaster payment for living away from home, the government cut off the payments forcing the people to move back home even though the visiting volcano experts said their was strong danger of another pyroclastic eruption. They were right and 2,000 more people died.
We have also witnessed Mount St. Helens recently, and other nearby volcanoes could cause even more fatal eruptions including major flooding as snow is heated. Anyone remember the 23,000 people killed by the eruption caused flood in South America a few decades ago? The Pacific northwest has a lot of volcano danger areas.
On March 6, the first earthquake struck the area. Another hit on March 11, and two more hit on March 13, it was reported.
It's crazy everywhere, near my home recently:
Statistically, volcano / lava eruptions have killed more life than any other process. The Permian Extinction event of 252 million years ago (252ma), that ranks as the worst of the great 5 extinctions, shows strong coincidence with the Siberian Traps flood basalt lava eruption. When the red stuff comes out, it is best to be far, far away. Given the nature of the vulcanology of the area, an eruption of Campi Flegrei would be high altitude, high ash that is maximum disaster for modern civilization pattens. UGH!
