Description: Jones (1952) reported minor explosive activity from Pavlof volcano in August, 1950, "culminating in November and continuing through the winter." He also reported Pavlof active on January 15, 1951, and "rhythmic" explosive activity on April 1, 1951, with the volcano quiet from May until fall.

Hantke (1955) reports that on July 31, [1950] there was a sudden onset of stronger explosive activity, and "in the following night there was glowing tephra [? Translation uncertain] to 1000 m."

The Syracuse Herald-Journal recorded in the August 1, 1950 edition: "Towering Mt. Pavloff spewed a column of smoke 25000 feet into the air today above a spectacular torrent of lava. A tiny Indian village 30 miles from the peak was threatened with burial in volcanic ash.

"The 8900 foot peak loacked 500 miles west of Anchorage, blew its top yesterday * * *."

Lachland MacDonald (1950) described the eruption a little differently: "Mount Pavlof was belching smoke 20,000 feet into the air. Fine ash covered an area of 30 miles and visiblity was impaired.

"First reports of the eruption, classed as a minor one by the experts, came from pilots on July 31. They spotted flames and lava pouring from a crater on the northeast slope. One witnessed chunks of pumice thrown hundreds of feet into the air and another described alternate coughing of steam and smoke punctuated by spurts of fiery lava."
