60°29'7" N 152°44'38" W, Summit Elevation 10197 ft (3108 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE
The 2009 eruption of Redoubt continues. The lava dome at the summit continues to grow. Webcam views show that vigorous steaming continues at the summit. Seismicity remains relatively low, but above background levels.
Rockfalls of fresh, blocky lava continue to occur, often creating minor, diffuse ash clouds within the summit region. If a lava dome collapse occurs, or if the dome is removed by a sudden explosive event, there could be significant ash emissions to >30,000 feet above sea level. Pyroclastic flows associated with dome collapse could initiate lahars and floods in the Drift River valley.
AVO is monitoring Redoubt volcano closely and the observatory is staffed 24/7. AVO will provide frequent updates of the volcano's status and the earliest possible warning of significant explosive activity and other hazardous phenomena.VENIAMINOF VOLCANO

Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW
During the past 24 hours, seismicity at Veniaminof has remained low, but above background levels. The seismicity has been comprised of primarily low amplitude volcanic tremor. Satellite data does not show any anomalous activity from Veniaminof. Nearby residents and pilots flying over the volcano have not reported any unusual activity.
