Megavolcano Eruption Scenario

If a megavolcano erupted, areas in a radius at least the size of Bloxas would be flattened. It could unfold in a series of explosive eruptions/vents and turn into one, or it could just erupt as one single massive vent. After such an eruption, a caldera would form after such an eruption. The ash cloud could extend more tha 2,500 miles. Ash, pumice, and hot blocks are likely to occur from this eruption, as well as pyroclastic flows and some lava. It will be literally the "shot heard around the world". It will be as quiet as a supervolcano, but as loud as 350 decibels. It will produce sonic booms up to a 7.57 kilometer radius, and Robloxians will either be dead or succumb to indefinite deafness.
