KVERT rose the alert level of the volcano to red, but later lowered it back to orange as the eruption, presumably a vulcanian event (caused by sudden released of overpressure in the conduit), seems to have been short-lived.
Strong steaming continues to be observed at the volcano and new explosions cannot be ruled out to occur with little to no warning.
