The residents of Juneau, Alaska, felt the after effects of a 100-year-old volcano eruption on Tuesday.
According to CBS, Juneau was covered in clouds of volcanic ash this morning, which was odd, since they haven’t experienced a major eruption recently. The National Weather service said that the ash that drifted over the city today came from the 1912 eruption of Novarupta, which was the largest volcanic blast of the 20th century.
According to the NWS, strong winds and a lack of snow on the volcano caused the ash from the 100-year-old volcano to drift over the Shelikof Straight and down across Kodiak Island. The ash traveled about 4,000 feet and caused an aviation alert.
The ash was first spotted by Brian Hagenbuch, general meteorologist at the National Weather Service Anchorage office. Hagenbuch said that it “looked foggy on the Larson Bay camera” and noted that the ash cloud looked like a “milky, dome-shaped plume.”
Hagenbuch told the Alaska Dispatch that wind will occasionally stir up ash from the 100-year-old volcano.
Thee Novarupta volcanic eruption of 1912 occurred on June 6th at the Katmai National Park and Preserve. The event lasted for three days and eventually covered the valley below 500 to 700 feet of ash.
