[Rockhounds] Earthquakes under a volcano near Alaska's largest city raise concerns

[Kreigh Tomaszewski]

An increase in the number of earthquakes under a volcano near Alaska’s
largest city this year has geologists paying attention.

Mount Spurr, about 80 miles (129 kilometers) northwest of Anchorage, last
erupted in 1992, spewing an ash cloud

nearly
12 miles (19 kilometers) into the air, prompting flights to be canceled and
people to don masks. Another eruption at the 11,100-foot (3,383-meter)
stratovolcano could be severely disruptive to the city, according to the
Alaska Volcano Observatory.

The observatory raised its alert status for Mount Spurr in October — from
green to yellow — when the increase in seismic activity became pronounced
and a ground deformation was spotted in satellite data. Observatory
scientist David Fee said Friday there have been about 1,500 small
earthquake below the volcano this year, compared to about 100 in a normal
year.
