description Semeru fumaroles Overview
The Semeru fumaroles are volcanic gas vents associated with the active summit area of Mount Semeru in East Java, Indonesia. Semeru is the highest volcano on Java and frequently produces short explosive eruptions from its summit crater, releasing ash and gas above the mountain. Its fumarolic emissions reflect heat and circulating fluids within the volcanic system, while changes in gas output form only one part of the broader monitoring used to assess activity.
