Kiska reported activity

Event Name : Kiska 1943/6

Start:

June 6, 1943

Observed

"Smoke":
Fumarolic or hydrothermal activity:

Description: Although newspaper articles in June, 1943 state that U.S. pilots bombing Kiska observed "sulfur boiling," dark smoke, and "lava streams running down the the slopes into the valley" it is likely that only fumarolic activity occurred, as Coats visiting the volcano in 1947 was unable to find any recent-looking lava.

Miller and others (1998) summarizes from Coats (1961): "Coats briefly visited Kiska volcano in 1947 and found no evidence of recent ash flows nor any active fumaroles; the youngest lava flows were more heavily vegetated at any given altitude than counterparts on adjacent islands known to have been erupted in the 20th century. The youngest lava flows before 1962 were probably between 100 and several hundred years old. Coats concluded that any events between 1905 and 1947 were at most solfataric."
