I know from observing Lyta’s life in the Plio-Pleistocene, volcanoes exercised enormous power over the lives of ancient animals. It’s hard to believe that they could globally blot out warmth and light, cause starvation, kill indigenous animal life. I watched Lyta’s life change dramatically after a combination of volcanic eruption and asteroid implosion destroyed her homeland.
“NASA caught the eruption of Russia’s Sarychev Peak. “It exploded with such force, the plume actually punched through the atmosphere. Note (in attached picture) how clouds around the volcano parted in a circular ring–that is a result of a shock wave produced by the upward blast. The plume is a mixture of brown ash and white steam. A ‘dirty thunderstorm’ complete with lightning could be in progress within the roiling cloud. The smooth white bubble on top of the plume is probably a mass of water condensing from air shoved upward by the rising ash column. If so, it is akin to the iridescent pileus clouds sometimes featured on spaceweather.com.”
Here’s a picture of the eruption caught from a jet high above the Earth. Can you ever doubt the effect multiple eruptions, over and over, could have on life below?
