A new eruption started at the volcano.
A new batch of magma has been shifting and accumulating inside the volcano’s feeder pipe over the past period. From the latest satellite imagery and webcam, new magma arrived in the summit crater and broke through the lava dome last evening.
More and more unstable hot lava material has been accumulating and later collapsed into hot rock falls, which might develop into dangerous pyroclastic flows.
