At a convergent plate boundary an oceanic plate subducts under a continental plate or another oceanic plate. The subducting plate takes volatiles such as water with it. These volatiles lower the melting point of the mantle rock. Molten material then rises to the surface, forming volcanoes. This is the most common cause of volcanoes on continents. Those that form from the sea floor often rise up to form volcanic islands. In truth, most of the world's volcanoes probably occur at divergent boundaries. However, the vast majority of those remain deep underwater where they are difficult to observe.
Lateral movement of the tectonic plates is the interaction that is the most likely cause of the volcano. The outermost shell of the planet is broken up into tectonic plates.

The best super volcano is most likely the "hidden" volcano in Yellowstone park.
An active volcano
People were most likely doing what they always did cause back then they wouldn't of know a volcano was about to explode.
