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.
