Soon we might be getting snow of a very different kind. It turns out the earthquake last Saturday was just one of a swarm of quakes surrounding Mt. Redoubt, a composite volcano in Cook Inlet to the west of here. A composite volcano, a.k.a. stratovolcano, erupts with both ash and lava. These are the Mt. St. Helens, Mt Pinatubo, Mt. Vesuvius types of potentially violent eruptions (unlike the quieter eruptions of the Hawaiian shield volcanoes).Mt. Redoubt is currently at Code Orange, which means an eruption is possible in the next few days to weeks. It lasted erupts in 1989-1990. Of course, how much this effects us depends on which way the wind blows, but current wind patterns have ash eruptions heading right over to Seward. If Redoubt erupts as it has in the past, we will probably just get a light dusting of ash, but you never know... Any ash, however, is bad as it can damage your respiratory system, clog air filters on cars and furnaces, and harm electronic devices. Plus the fine dust gets everywhere and is hard to clean up. So I am torn. I want an eruption because it is the raw earth alive and active; it is science in action. But I am also not too clean on not being able to drive my car, turn on the heat or go outside.
The two pictures below are from the 1990 eruption. The peak in the background on the left Iliamna, another of the many volcanoes in Cook Inlet. Everyone thinks of Hawaii when they think of volcanoes, but Alaska has 40+ active volcanoes, more than all of the Lower 48 and Hawaii combined.
