A great killer

I have many hobbies, the most of them are related to science but unfortunatelly I hate science , so I have them as entertaiment . In this case I'm going to talk about geology, it's a theme for what I have felt curiosity all my life, especially the volcanoes.
Simply I think it's is really awsome the power and strengh they have and in some cases they can create terrible catastrophes .
Some of the most dangerous volcanoes of the world are; Mauna Loa in Hawaii, Toal Volcano in Philipines , Galeas in Columbia , Anak Krakatoa and the mounts Vesuvius and Etna in Italy .
But the deadliest volcano of the world clearly is the Yellowstone Caldera in the United States of America , different from the other volcanoes the fact that makes Yellowstone so dangerous is  that in the hipothetical case that this volcano erupts the whole american continent would be destroyed and the great amount of ashes expelled by the volcano would provoke a volcanic winter due to the ashes wouldn't let sunshine penetrate into the atmosphere , but don't worry experts predict the next eruption will take place circa 900.000 millions of years.
