Using the composition of fluid seepage from the magmatic-hydrothermal system of Kawah Ijen volcano, Indonesia, as a monitoring tool

K Berlo, V van Hinsberg, BH Purwanto… - Journal of Volcanology …, 2020 - Elsevier
The lake waters of Kawah Ijen volcano are concentrated hyperacidic brines that obtain their
composition from volcanic gases and water-rock interaction. Lake water and hydrothermal …

Stratification at the Earth's largest hyperacidic lake and its consequences

C Caudron, R Campion, D Rouwet, T Lecocq… - Earth and Planetary …, 2017 - Elsevier
Volcanic lakes provide windows into the interior of volcanoes as they integrate the heat flux
discharged by a magma body and condense volcanic gases. Volcanic lake temperatures …
