A seismic crisis just began on the French island of Reunion. With a population of more than 850,000, this island might see a new volcanic eruption in the short to mid term future. Piton de la Fournaise's magma chamber is currently highly pressurized, mostly filled with magma, and is predisposed to produce a new eruption at the volcano's summit, perhaps on its eastern flank. While such a new eruption is not guaranteed, it likely would be primarily effusive although it might have some strombolian components to it.
