A remote Alaska Volcano that erupted in March is again showing signs of life. Scientists at the Alaska Volcano Observatory on Friday morning detected seismic activity beneath Pavlof Volcano that can signal a low-level eruption. Instruments detected tremors typically related to the movement of fluids.

“In this case, lava is considered a fluid,” geophysicist Dave Schneider said. “It can also be the hydrothermic systems, or hot water, percolating through the volcano.” The observatory upgraded the Pavlof’s status from normal to a volcano watch. The observatory could not tell whether the volcano has sent up an ash cloud because the 8,261-foot summit is obscured by clouds. “We’re continuing to watch carefully and see how this develops,” Schneider said.
