The alert level was just raised at a segment of the active volcano that comprises the Portuguese island of Pico in the Azores. However, this thankfully did not involve the towering peak of Mount Pico, but rather a completely offshore and submarine portion of its edifice several kilometers away from the shoreline. Today's video will discuss why the alert level was raised, and speculate what might be occurring. Disclaimer: Due to a lack of publicly available information on the "Cachorro Submarine Volcanic System", much of what I say in today's video could be incorrect.
