The Alaska Volcano Observatory has raised the caution level at Kupreanof Volcano on the Alaska Peninsula, a normally quiet peak that hasn\u2019t had a major eruption in almost 570,000 years.<\/span><\/p>\n

\u201cIt\u2019s a typical Alaska volcano. It\u2019s not dormant by any means,\u201d said Matt Haney, the U.S. Geological Survey Scientist-in-Charge at the observatory.<\/span><\/p>\n

On Tuesday, the observatory <\/span>issued an advisory notice<\/span> saying that it had detected a rising number of earthquakes and sulfur dioxide emissions at the peak.<\/span><\/p>\n

\u201cThis activity is likely caused by a magmatic intrusion beneath the volcano,\u201d the observatory said in the notice.<\/span><\/p>\n

\u201cIt\u2019s been a classic volcanic unrest sequence \u2026 From the science point of view, it\u2019s been very fascinating to see unrest develop at Kupreanof,\u201d Haney said.<\/span><\/p>\n

Rising unrest does not mean an eruption will happen or is even likely to happen. Last summer, Mount Spurr near Anchorage showed a rising level of activity that appeared to indicate a likely eruption. Despite those signs, no eruption took place and seismic <\/span>activity has since declined<\/span>.
\n<\/span><\/p>\n

A 6,217-foot peak, Kupreanof is in a particularly remote part of the Alaska Peninsula National Wildlife Refuge, 505 miles southwest of Anchorage. The closest permanently inhabited community is Perryville, 26 miles to the southeast.<\/span><\/p>\n

Though isolated, Kupreanof \u2014 like most of Alaska\u2019s volcanoes \u2014 is near trans-Pacific flight routes, and a sufficiently large eruption could disrupt cargo and passenger flights between North American airports and Asia.\u00a0<\/span><\/p>\n

Haney said by phone on Thursday that the observatory detected an escalating string of earthquakes beneath the volcano starting in February and continuing through this week.<\/span><\/p>\n

On Wednesday, instruments recorded the largest earthquake yet, measured variously at Magnitude 3.5 and 3.0.<\/span><\/p>\n

Satellites have also measured rising concentrations of sulfur dioxide near Kupreanof. That gas is a standard sign of magma moving near the surface of the Earth.<\/span><\/p>\n

\u201cIt\u2019s not just one of our monitoring data streams that\u2019s showing (activity) above our background levels. Now it\u2019s seismicity and gas. When we have two of our data streams, that\u2019s really making the diagnosis with higher confidence that there has been a magma intrusion beneath Kupreanof,\u201d Haney said.<\/span><\/p>\n

There are no historic records of a confirmed eruption at Kupreanof. In 2015, a mariner reported \u201cblack smoke northwest of Ivanof Bay,\u201d likely from Kupreanof, and in 1987, a pilot <\/span>reported<\/span> what may have been a small eruption.<\/span><\/p>\n

\u201cAlthough reports from Kupreanof are uncommon, steaming from Kupreanof has been noted for at least the last 75 years,\u201d the observatory notes in <\/span>its description<\/span> of the 2015 report.\u00a0<\/span><\/p>\n

The last confirmed eruption was <\/span>about 570,000 years ago<\/span>.\u00a0<\/span><\/p>\n

As a result, the volcano has no permanent monitoring network.\u00a0<\/span><\/p>\n

Hannah Dietterich, a research geophysicist at the observatory, said on Wednesday that she and others at the observatory have begun arranging more regular satellite measurements, including with instruments designed to measure whether the ground around the volcano is bulging upward.<\/span><\/p>\n

Satellite images taken this week show Kupreanof still covered in a thick layer of ice and snow, indicating that the peak has not warmed to the point of melting that accumulation.<\/span><\/p>\n

Haney said that in addition to satellite measurements, the observatory may use a helicopter to take a \u201cquick-deploy\u201d monitoring station to the volcano in July, during a previously scheduled trip to another nearby peak.<\/span><\/p>\n
