Mud remnants from phreatic eruptions marking the summit lake of Rincon de la Vieja were found by volcanologists to Copelares, 2 km from the crater on November 15. This sludge were found on the leaves of ferns and shrubs.
The inspection showed a decrease of 2 meters from the lake level in four months. Degassing marked the Laguna Caliente and a gas plume reaches 300 meters high. Nineteen phreatic eruptive episodes were recorded in the space of half past one hour, reaching 10-20 meters in height.

Significant accumulation of materials in the northern sector could generate lahars
