2002-2007 activity of Chikurachki Volcano (Paramushir Island, Northern Kuriles) based on KVERT data

Abstract

Chikurachki volcano resumed its eruptive activity in 2002 after strong explosive-effusive eruption in 1986. Over the period of 2002-2007: in 2002, 2003, 2005 and twice in 2007, the volcano produced five moderate explosive eruptions. The longest volcano eruption was observed in 2002 and the strongest in 2003. During this period ash column rose up to 6 km ASL (2003), ash plumes extended for 700 km from the volcano. Since 2002 Kamchatkan Volcanic Eruption Response Team staff in the Institute of Volcanology and Seismology FEB RAS has been realizing continuous satellite and episodic visual monitoring of the volcano and recording possibly any changes in its activity.
