Pavlov Volcano, a 8,261-foot cone rising from the Alaska Peninsula southwest of Anchorage, blasted a plume sparkling with lightning almost four miles into the sky on Aug. 30, continuing an eruption that began in mid-August and could be building toward a colossal explosion.
National Weather Service observers in Cold Bay reported a substantial plume and associated lightning emanating from Pavlof Volcano up to 20,000 ft (6,000 m) above sea level. The plume was also visible in images from the Pavlof web camera located in Cold Bay.
