The evolution of the behavior and physico-chemical characteristics of solutions in the new geyser in Uzon Caldera, Kamchatka

摘要

This paper is a study of variations in the behavior and physico-chemical characteristics of solutions in the geyser that formed in 2008 in the place of a pulsating spring in Uzon Caldera. We describe the features of this geyser's activity in 2009 and 2010. Overheating of water is for the first time described, rising to reach100. 13°C at the mouth of a geyser during an eruption. We discuss the compositions of the solutions and free gases in the geyser, the possible source depths of the solutions, and the causes of geyser generation.
