Accordingto the Alaska Volcano Observatory , the Aleutian Islands in Alaska are currently the site of a singular and unsettling natural occurrence . Threevolcanoesare erupting , and a quaternary seems to be on the verge .
key them as “ restless , ” the AVO hasdocumentedspewing ash and steam from the Great Sitkin , Pavlof , and Semisopochnoi volcanoes and declared them an “ orangish ” layer threat , which intend they ’re erupting . The other , Cleveland , is set to “ yellow ” as it ’s yet to break out .
The AVO uses surveillance cameras as well as eyewitness accounts to monitor volcanic activity . The snow - covered stratovolcano Pavlof is soon the most active , with some pocket-size explosions and ash tree that’stravelingroughly six nautical mile before dissipating . It sits 35 mile from the town of Cold Bay , but no threat to the country has been detected .
A lava foundation is active at the Great Sitkin , which is near two small villages . The vent on Semisopochnoi appear to be blowing ash tree up to 10,000 feet in the air .
Meanwhile , seismal activity has been notice in the Cleveland volcano , which erupted just last year . There have also been smallearthquakesrecorded at the Atka Volcanic Complex Volcano .
Geologists at the AVO are n’t overly concerned at the moment . While multiple fighting volcano guarantee continued monitoring , the eruptions are not conceive to be life - endangering . The AVO does caution that Pavlof has been known to increase the severeness of its eruptions with little to no word of advice .
Alaska has the somewhat dubious honor of being host to the twentieth century ’s mostsignificantvolcanic bam , when Novarupta go up in 1912 . hold out three days with ash tree spreading for hundreds of miles , it created the Katmai Caldera and the fittingly named Valley of Ten Thousand Smokes .
