With Yellowstone shaking, we ask how the eruption of a supervolcano would really affect the US
Unknowncountry has been monitoring the increased earthquake activity at Yellowstone Park in Wyoming, and considering the potential effects of a Super-volcano eruption. The National Park is perched on top of a simmering Super-volcano which has been responsible for some of the largest and most cataclysmic volcanic eruptions in known history.
Last week’s ‘Weekender’ feature documented an increase in earthquake swarms around the Yellowstone area – over 130 in September alone – and a 3 inch swell in the volcano’s caldera every year for the past three years suggesting that the magma underneath is rising. The cause of the tremors has not yet been determined, but could be influenced by planetary alignments according to some experts and peer-reviewed studies.

An ongoing controversy about what happened to end the last ice age in a huge catastrophe has been resolved. Something gigantic hit the Earth, leading to massive fires followed by flooding as ice sheets melted, and the extinction of huge numbers of animal species. Additionally, there is now provocative evidence that a human civilization very different from our own, but possibly quite widespread, was also destroyed. Until recently archaeologists disputed any timeline that suggested the presence of complex organized societies until about 5,000 BC.
