Dont need to have big eruption simulation just see smoke from volcano craters could be more immersive. Maybe like smoke from chimneys. Have around 1500 volcanoes in acivities in the world. A good start could make Indonesia’s volcanoes smoke first. Im not a developer I dont know if have API for that.
I took this pic from plane in Indonesia. A lot of volcanoes have smoke like this before they erupt.
