This earthquake activity is part of the inflation in volcanoes in the volcanoes in this area because of influx of magma at 3 km to 8 km depth. While no eruption has not yet happened that is the most likely outcome of all of this activity. When this enters the eruption phase is something that cannot be predicted.
