A powerful explosion occurred at the volcano today (24 Sep) at 12:41 local time, producing an ash plume that rose to 38,000 ft (11 km) altitude. It generated several pyroclastic flows, some of which surpassed the 350 m high western caldera wall.

The volcano had been relatively quiet during the past months. This morning's explosion could have been a result of gas pressure that slowly build up under the lava dome's plug of viscous lava.
KVERT raised the alert level to red, and lowered it back to orange afterwards as no new eruptions followed and the ash had dissipated.
