This image was taken on Jan. 31, 2006, during a period of “episodic” emissions of steam and ash plumes. It “shows three volcanic flows down the north flank of Augustine as white (hot) areas,” writes NASA. On Feb. 8, 2006, five ocean-bottom seismometers were deployed in the area to assist the Alaska Volcano Observatory (AVO) in studying the eruption. These seismometers were used because this volcano, like many others, is often hard to see on Earth because of weather. Consequently, we are left to appreciate even more the contributions NASA has been able to make to volcanic study.
