An ash cloud from Shishaldin Volcano reaching 28,000 ft (8.5 km) has been reported by aircraft in the vicinity of the volcano. This follows a several-hour increase in seismic activity. In response, the Aviation Color Code is being raised to RED and the Volcano Alert Level is being raised to WARNING.
Based on previous eruption cycles, significant ash emissions are likely to continue for several hours. Pyroclastic and mudflows are likely on the immediate flanks of the volcano.
