Cambridge Univ Press, 354 p. By the morning of 9 August, seismicity declined and ash emissions were not observed in either satellite data or from pilots or passing mariners.
Vigorous steam-and-gas plumes that rose above the crater and drifted up to 32 km downwind were observed on 3 and 4 September by passing mariners. Winds were moving the gas in a large counterclockwise loop over the Pacific Ocean and back toward Alaska, but also spreading streamers over the Arctic and eastward across the United States and Canada. Kasatochi Island's physiographic changes resulting from the 7-8 August 2008 eruption.

By 7 August 2008, the number and magnitude of earthquakes increased, accompanied by volcanic tremor. Photo Radar Scale: Colors represent drainage density as shown in the key bottom left. However, some fraction may be due to increased instrument sensitivity achieved since that time.

Clouds mostly prevented satellite image observations; weak thermal anomalies were detected on 5 and 7 September. Rozell, N.
From Krakatau to Bali - Java Indonesia. The bright clouds provide good contrast for the volcanic plume, which is dark brown.

Wang, B. Williams, J. Fieldwork in summer 2009 determined the locations of various rills and gullies at representative locations on the island. A lava flow may have been emplaced during the first historical eruption in 1760.
During the days after 9 August, eruptive activity declined gradually. Pulse 2 began at 01: On 7th August three eruptions occurred at Kasatochi volcano is Alaska.
