Swarm of quakes at Alaska volcano could mean eruption coming
The HinduA swarm of earthquakes occurring over the past few weeks has intensified at a remote Alaska volcano dormant for over a century, a possible indication of an impending eruption. The Alaska Volcano Observatory raised the alert level to advisory status for Tanaga Volcano late Tuesday after the quakes became very vigorous. “We started seeing a whole lot of earthquakes occurring, one after the other, several per minute,” said John Power, a research geophysicist with the U.S. Geological Survey stationed in Anchorage at the Alaska Volcano Observatory. “It’s very different than what you would see, for example, in Hawaii, Kilauea or Mauna Loa, where you see these beautiful red rivers of lava flowing down the side of the volcano," Power said. To the east of Tanaga is Takawangha, a 4,75-foot volcano that is mostly ice-covered except for four craters, the Alaska Volcano Observatory says.
