Makushin Volcano is Unalaska Island's highest peak and one of the most active volcanoes in Alaska. The Alaska Volcano Observatory is planning to install a series of seismic instruments on Mount Edgecumbe near Sitka after preliminary measurements showed magma moving deep below the Mount Fuji-shaped volcano.. Along a remote, roughly 800-mile stretch of Alaska's Aleutian island chain, three volcanoes are erupting at the same time, with at least two spewing low levels of ash and steam. All of them occurred at with depths less than 6 miles (9 km) below sea level. Partially because of their experience, Kluting and Turley have been following events more closely than most. The eruption started almost two weeks ago and have steadily grown stronger, but they do not yet pose a concern to experts. The two other volcanoes the Great Sitkin Volcano and Semisopochnoi Volcano sit hundreds of miles away. AVO monitors seismic activity at potentially active volcanoes across Alaska and calculates locations and magnitudes for earthquakes (typically magnitude 3.0 and below) near the 32 active volcanoes where AVO operates seismic networks. No historical eruptions are known from Takawangha; however, field work shows that recent eruptions have occurred and it is possible that historic eruptions attributed to Tanaga may instead have come from Takawangha.
