Yellowstone : Michio Kaku Scientist warns Millions could be Killed if Super-Volcano Erupts

By Amber William

The Yellowstone Caldera is the volcanic caldera and supervolcano located in Yellowstone National Park in the United States, sometimes referred to as the Yellowstone Supervolcano. The caldera and most of the park are located in the northwest corner of Wyoming. The major features of the caldera measure about 34 by 45 miles (55 by 72 km).
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. Earth's volcanoes occur because its crust is broken into 17 major, rigid tectonic plates that float on a hotter, softer layer in its mantle.

The report looked at other major geo-hazards facing the globe, including earthquakes, drought, asteroids floods, tsunamis, hurricanes, avalanches and wildfires.

Large earthquakes and tsunamis have happened more in the last 2,000 years, meaning there was better preparedness.

The report concluded: “Volcanic eruptions can have more severe impacts through atmospheric and climate effects and can lead to drastic problems in food and water security, as emphasized by the widespread famine and diseases that were rampant after the Laki 1783 and Tambora 1815 eruptions.

“Hence extreme volcanic eruptions pose a higher associated risk than all other natural hazards with similar recurrence periods, including asteroid impacts.”

The eruption of Tambora on Sumbawa, Indonesia killed about 100,000 people, but ash clouds meant there was no summer the following year and it was “one of the most important climatic and socially repercussive events of the last millennium,” the report said.

The earlier Icelandic event killed close to 10,000 instantly, but the long-term, effects wiped out 25% of the population and were felt across the planet.

A famine in Egypt reduced the population by one sixth, 25,000 died in the UK from breathing problems and there was worldwide extreme weather.

Similar scale events today would be much more catastrophic, the team warned, due to

much bigger populations, global travel and food chains and reliance on technology.

Worryingly, scientists say research over the last 300 years of volcanic activity shows we are currently in a "volcano season" meaning increased activity.

Volcanoes are also more likely from November to April in the northern hemisphere when ice, rain and snowfall can compress the bedrock.
