It is not clear why, but when the earth cools and sunspots are at their minimum, volcanic activity on earth seems to increase, especially super volcanos that leave a significant eruption signature. See graphic below:
The most dangerous super volcano in the US is a volcanic plume that has been sliding northeast, across Idaho for millions of years and last erupting about 640,000 years ago in north-western Wyoming. The Yellowstone Caldera was created by a massive volcanic eruption approximately 640,000 years ago. Subsequent lava flows filled in much of the caldera.
UK Express has a volcano warning:
Instances of volcanic eruptions are their highest for 300 years and scientists fear a major one that could kill millions and devastate the planet is a real possibility.
Experts at the European Science Foundation said volcanoes – especially super-volcanoes like the one at Yellowstone National Park, Wyoming, which has a caldera measuring 34…
