Megavolcano at Yellowstone may be spent
According to a Wikipedia article, the Megavolcano at Yellowstone that extends over the state lines of Idaho and Wyoming in the United States may be through with exploding. An excerpt from the extensive article says:
The appearance of light magmas indicates that the uppermost portion of the continental crust has been consumed, …. In this case Yellowstone could be expiring. It could be another 1-2 million years before a new supervolcano is born to the northeast, and the Yellowstone Plateau volcanic field joins the ranks of its deceased ancestors in the Snake River Plain.
Now that my End of the World 2012 Movie is almost ready for distribution, I’m putting together a Kindle eBook version of the movie. In doing so, I looked up information about megavolcanoes and especially the megavolcano at Yellowstone.
In a previous post dated May 31, 2010, I had reported that Yellowstone usually erupts every 600,000 years. Since it’s been 640,000 years since it’s last eruption, it was due for another one at any time. However, the article quoted above is of the opinion that Yellowstone may be at the end of its megavolcanic activity. That sounds good to me.
I wanted to share this information with you, because you may have read, as I have, that, according to some sources, Yellowstone is overdue for a world-shaking megaexplosion. I like to find a balancing opinion.
