Since that explosion, seismicity has decreased and satellite images show that the ash cloud has detached from the vent and is moving towards the east. Additional explosions are possible and the Aviation Color Code remains at RED and the Volcano Alert Level at WARNING.

Marine and aviation traffic should monitor the situation, AVO alerts and be prepared to take action.
