Super Volcano!

74,000 years ago the human population was reduced to about 10,000, worldwide.  Humans nearly became extinct. This resulted from climate change that occurred after the eruption of Mount Toba, a super volcano that released more than 1000 times more ash and volcanic gas into our atmosphere than the eruption of Mt. St. Helens.  Super volcanic eruptions have altered earth’s biological history.   At least 8 exist in the world today, and two lie within the United States.  Yellowstone is a super volcano that some feel is due to erupt.  How likely is this, and what risk does a super volcanic eruption pose to modern civilization?   Ron Smith, retired planetarium educator, will uncover past super volcanic eruptions, one even occurring in Southern Utah.  Find out what risk we all face from a Yellowstone eruption. $5 cash only at the door of a Room for Thought.
