Description: Robinson (1948) reported a small steam plume from Shishaldin on June 6, 1946. Coats (1950) reports a minor explosive eruptions at Shishaldin from August - September 1946, December, 1946, and January, 1947. Hantke (1951) reported "ashfall over the Aleutians" in 1946 from Shishaldin. The January 10, 1947 edition of the Sitka Sentinel reports "A second volcanic disturbance in Alaska's Aleutian islands was reported today by the Navy, which said 9387 foot Mount Shishaldin on Unimak Island was erupting with such violence that it showered ashes two inches deep on the village of False Pass 20 miles away. * * * The USS Passiac, a netlayer, visited False Pass January 2 and reached Dutch Harbor today with news of the new eruption. Postmaster Frank Bell of False Pass told Passiac crewmen that Shishaldin had been erupting every five days for several weeks."

The Associated Press article from the January 10, 1947 edition of the Walla Walla Union-Bulletin gives a few additional details: "Quartermaster 1-c Allan E. Sitter of Los Angeles, said he observed heavy black puffs of smoke bursting from the mountain. False Pass residents said the eruption caused electrical disturbances which looked like lightning flashes and lighted the entire area. Sitter said the village was covered with a two-inch coating of volcanic ash, and that cinders an inch and a half in diameter, lay on the wharf."

A January 11, 1947 Associated Press article describes the eruption: "The eruption of Mt. Shishaldin * * * also was photographed from Lieutenant Kissling's plane.

"He said cinders, smoke, and steam were spewing from an opening on the south side of Shishaldin's cone, and were being carried northward, obscuring the view of that side of the peak.

"Shishaldin's activity, at the time, was of less intensity than had been reported by Frank Bell, postmaster at False Pass. That village, about 30 miles east of the peak, has a blanket several inches deep of cinders and ash."

Meredith (1998) reports that on September 7, 1947, she could see "Mt. Shishaldin's smoking peak about 20 miles away."
