An international team of scientists and historians has found evidence connecting an unexplained period of extreme cold in ancient Rome with an unlikely source: a massive eruption of […]

Fountain Paint Pot. Credit: National Park Service. Throughout Earth’s long history, volcanic super-eruptions have been some of the most extreme events ever to affect our planet’s rugged surface. Surprisingly, even though these explosions eject enormous volumes of material— at least 1,000 times more than the 1980 eruption of Mount St. […]

These giant mounds of fossil stromatolites from about 2.5 billion years ago are located in South Africa. For scale, notice a person’s dangling legs at the top center. These layered minerals were deposited on an ancient coastline by communities of microbes, including photosynthetic bacteria that generated oxygen. The new study […]

Why a big volcanic blew-up at the popular travel destination Santorini 3200 years ago, but just a few hundred kilometers away, there was no drama at the volcanoes on Aegina, Methana and Poros islands? At Santorini, the explosion was so intense, the volcano collapsed into a caldera and filled up […]
