Dhaka, March 13 -- Scientists are warning that a volcano near Anchorage is exhibiting signs of increased activity, raising the possibility of an eruption in the coming weeks or months.

The Alaska Volcano Observatory reported Wednesday that recent aerial surveys detected a significant rise in volcanic gas emissions at Mount Spurr. While an eruption is not guaranteed, the observatory noted that the likelihood has increased.

"If an eruption occurs, we expect to see heightened seismic activity, increased gas emissions, and surface heating in advance," the observatory stated. It added that stronger signs of unrest could provide several days to weeks of warning.
