Whether this is caused by an intrusion of fresh magma which in turn could lead to a new eruption is unclear. For the time being, the volcano's alert level remains at 2 (out of 5) where it has been since Oct 2013. While the recorded signs of unrest are weak, sudden phreatic explosions could occur any time and pose a significant risk if visiting the crater area.
