The Leningrad astronomer Dr Nikolai Kozyrev has made another remarkable spectrographic observation of the Moon’s vulcanism, according to Novosti.

Yellowstone's near future is the Utah of today, with vulcanism.

We were five to six thousand feet above sea level now, on a high plateau full of the evidences of recent mountain-building and vulcanism; we were in the Fire-Hills of the Sembensyen Range.

The origins of this event are not clear but suggestions include vulcanism and climate change and the planet may have warmed or cooled rapidly.

No geological evidence supports the idea of an unusual frequency of vulcanism or floods 3,500 years ago.
