Less than ten minutes ago there was another ash explosion. I don't have details on it yet, but I saw the event captured on the webcams. So there's more ash heading toward the farm. For joy, for joy.
By the way, over the past three hours there has been dozens of earthquakes at the summit. The largest is listed as being a 4.0. I bet that shook things up! I'm guessing they are causing the rockfalls, which ultimately may lead to the big explosive event that is being anticipated. Once enough rock plugs the throat of the volcano, the pressure will build up to the point of a massive summit eruption.
