Alaska's Mt. Redoubt volcano has remained conspicuously quiet

There was genuine concern after a lengthy series of violent eruptions that Redoubt's tempestuousness would last through the summer and spoil the fishing business on and near the Kenai Peninsula, east of Redoubt across the Cook Inlet.

In fact, with the peak July and August seasons behind, resort and fleet operators can say they dodged a bullet. Redoubt, which in 1989 and 1990 erupted sporadically over a period of seven months, remained on an yellow alert code throughout the summer.

The yellow code means a volcano is exhibiting signs of elevated unrest. An orange code means a major eruption is imminent, suspected or underway but poses a limited hazard to aviation because of insignificant volcanic ash emissions. A red code is used when a major eruption is imminent, underway or suspected with hazardous activity on the ground and in the air.

Presently, according to the Alaska Volcano Observatory, the cautionary advisory remains in effect: "In the unlikely event of a major dome collapse, significant ash production, hot block-and-ash flows and flooding in the Drift River valley could all result."

If Redoubt erupts, Outposts will post the news. Meanwhile, I just wanted to share the image, one of many posted on the observatory website.
