The eruption of some of the largest volcanoes on the planet could be predicted several decades before the event, according to researchers.

Analysis of rock crystals from the Greek island of Santorini suggests eruptions are preceded by a fast build-up of magma underground, which might be detected using modern instrumentation.

Such volcanoes can produce enough ash and gas to temporarily change the global climate.

The research is in the journal Nature.

Volcanologists refer to history's largest volcanoes as "caldera-forming eruptions", as the magma ejected is so voluminous that it leaves a massive depression on the Earth's surface and a crater-like structure known as a caldera.

1. Interesting... Say we could predict the eruption of the Yellowstone Caldera

Even with decades of warning, what could we do to prepare? Move everyone out of North America? Start stockpiling food for the ensuing volcanic winter? Mass suicide?

2. If they Yellowstone super volcano decided to erupt in full force...

there would be no where to hide.

You would either die a quick death or a horrible slow death. it all depends on where you live.
