A volcano in southern Alaska is rumbling with seismic activity, which hints at the possibility that it might soon erupt.

An active volcano near Alaska's most populated city could be on the brink of eruption, according to scientists who are constantly monitoring a potential threat.

Mount Etna, standing around 3,300 meters (10,800 feet) high, erupts with smoke streaming from its summit and lava spilling from the new “Bocca Nuova” crater, according to Reuters.
