Our volcano’s are mostly strato-volcano’s, very tall cone shaped, we are at the northern part of the Ring of Fire, we have a LOT of seismicity, like thousands of little pressure pop-off valves all the time, which is good.
Krakatoa collapsed and sea water rushed in, and it blew up, not so easy to happen here but could happen to St. Augustine, it is its own island.
Hey Unk, how far are you from this volcano? Are you seeing any ash?
