Last Thursday I watched an interesting documentary about supervolcanoes. This type of volcano doesn't have the typical conical shape; rather, it forms a depression in the ground called "caldera" (a word from Spanish meaning "cauldron" or "boiler").
Most of the documentary centred on the active supervolcano situated in Yellowstone National Park, USA. Visitors to the park may not know that its great beauty conceals a ticking time bomb. Were the supervolcano to erupt, the consequences would be catastrophic.
A supervolcano is a lot more powerful than a normal volcano. In fact, experts agree that an eruption would cause a global disaster, followed by massive loss of life. Moreover, the subsequent climate change would affect the world economy and the food supply. Our whole existence would be turned topsy-turvy.
The scary part is that the eruptions of the supervolcano in Yellowstone National Park follow a cycle of approximately 600,000 years, and the next eruption could happen in our lifetime. That, fortunately, seems a remote possibility.
Anyway, be that as it may, I don't see the point in worrying too much. Let's try to enjoy life since we don't really know when it will end. It could be tomorrow or in a thousand years. As the Americans say, that's my two cents.
