Rincón de la Vieja , Costa Rica : the water level in the lake has dropped than two meters .

Sludge from phreatic eruptions of the Rincón de la Vieja were found by volcanologists to Copelares, a site located two kilometers from the crater.
A detailed report of the National Seismological Network (RSN) and the Science Research Center of the Earth (CICG), both from the University of Costa Rica (UCR), was published on November 15.
This observation has been made by volcanologists Raul Mora, Gino Gonzalez, Carlos Ramirez and Yemerith ALPIZAR, during an inspection made between Wednesday and Friday.
The document indicates that the waste of sludge were observed on sheets of different kinds of ferns and shrubs. Raul Mora said that perhaps this material was swept away by the wind.

The experts said the hot lake has a large vent and the gas cloud reached up to 300 meters high.
In addition, the report indicates that the water level in the lake has dropped than two meters compared to other measurements made in July.
They also said that during a period of half past one, they recorded 19 phreatic eruptions, which reached between 10 and 20 meters high.
Scientists have confirmed, as they did on November 6, in the North East of the volcano, there is a significant accumulation of material, which could cause lahars (mudflows, stone).
