Factors that influence the presence of hot crater lakes at active volcanos
This paper proposes a new physical model of volcanic crater lakes, examines the sustainability of their temperature and level, and then applies this model to some recent observations of crater lakes. They find that high temperature lakes without sealed bottoms are sustainable, despite expectations that extreme activity, heat input, evaporation and numerous phreatic eruptions would cause a lake to dry out. This contradicts earlier research [Pasternack and Varekamp, 1997]. The applications of this study are interesting as they give some constraints on the behavior of volcanoes with crater lakes.
