climate response to the July 12, 2008, eruption of Okmok volcano and the August 8, 2008, eruption of Kasatochi volcano, which injected a total of 1.6 Tg of SO 2 into the Arctic upper troposphere and lower stratosphere (0.1 Tg from Okmok and 1.5 Tg from Kasatochi). It is one of the volcanoes in the world that formed new islands in historic times. The significant explosive eruptions of Okmok and Kasatochi volcanoes in 2008 tested the hazard communication systems at the Alaska Volcano Observatory (AVO) including a rigorous test of the new format for written notices of volcanic activity. Initial effects of the August 2008 volcanic eruption on breeding birds and marine mammals at Kasatochi Island, Alaska. Chronology of the Swarm [8] Based on retrospective analysis, the first earthquake in the Kasatochi swarm was located by AEIC on 7 July (Figure 2). The reason that this happens is because of the ash particles that get scattered throughout the atmosphere. When Alaska's Kasatochi volcano erupted in 2008, people all over the world saw unusually beautiful orange and coral hues in sunsets. Estimates of the original area covered by Explosive Eruption of Kasatochi, Cleveland, and Okmok Volcanoes in Alaska. The mean slope of the southern flank (about 18 degrees) is considerably less than the mean slope of the northern flank (about 45 degrees). The island consists of a single, undissected cone with a central lake-filled crater about 0.75 km in diameter. Kasatochi is a remote island forming the peak of a mostly submerged stratovolcano rising to 314 m a.s.l. During a volcanic eruption, sunlight needs to travel through gas and fine ash particles. This scatters the sunrays at the spectrum's red end, giving the sunset a more vibrant reddish appearance. Kasatochi volcano (Andreanof Islands, USA) - Smithsonian / USGS Weekly Volcanic Activity Report for 3 September-9 September 2008 (Continuing Activity) AVO reported that during 3-9 September seismic activity from Kasatochi, detected by stations approximately 40 km W on Great Sitkin island, was low.
