AK: Earthquakes prompt concerns about possible volcano eruptions
ANCHORAGE, Alaska — Not one but two volcanoes on the same island in Alaska's Aleutian chain were rocked by earthquakes on Friday, prompting concerns about a possible eruption.
Elevated earthquake activity was reported at both Tanaga and Takawangha volcanoes on uninhabited Tanaga Island, hundreds of miles from Anchorage.
"If an eruption were to occur, it is uncertain at this stage if it would come from Takawangha or Tanaga," officials at the Alaska Volcano Observatory said in a statement that raised the alert level for the two volcanoes.
Even though the frequency of tremors slightly diminished Friday, earthquake activity at the volcanoes was still occurring about every minute or two.
