ANCHORAGE \u2014 A remote Alaska Volcano that erupted in March is again showing signs of life.<\/p>\n
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.<\/p>\n
\u201cIn this case, lava is considered a fluid,\u201d geophysicist Dave Schneider said. \u201cIt can also be the hydrothermic systems, or hot water, percolating through the volcano.\u201d<\/p>\n
The observatory upgraded the Pavlof\u2019s 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.<\/p>\n
\u201cWe\u2019re continuing to watch carefully and see how this develops,\u201d Schneider said.<\/p>\n
By early afternoon, satellite sensors had not detected heat associated with lava flowing from vents on the mountain, Schneider said.<\/p>\n
That wasn\u2019t the case March 27. Pavlof that day sent an ash cloud soaring to 37,000 feet, and the observatory almost immediately detected thermal readings indicating lava coming out.<\/p>\n
Weather in late March also was uncharacteristically clear, and the ash cloud was spotted by pilots. The cloud drifted across interior Alaska to northern Canada.<\/p>\n
Volcanic ash is sharp and abrasive and can cause jet engines to shut down. Alaska Airlines canceled nearly 70 flights to Fairbanks and Alaska communities over two days<\/p>\n
Pavlof is conical and about 4.4 miles in diameter. The volcano has erupted more than 40 times since record-keeping began in the late 1700s.<\/p>\n
It\u2019s not uncommon for eruptions to recur. Pavlof erupted intermittently for more than two years from April 1986 to August 1988.<\/p>\n","protected":false},"excerpt":{"rendered":"
