Is Costa Rica’s Rincon De La Vieja Volcano Ready to Erupt Again?

The Rincon de la Vieja volcano erupted on January 30th. The lake level dropped about 10 to 15 meters leaving fumaroles exposed. They now throw gases directly into the air rather than into water.

The sharp decrease in the level of water in the lake can be seen when comparing photos from 2018 to 2020. When comparing the photos you can also notice a slight wilting in the vegetation because of the acidity of falling fragments of rock that are between 400 and 800 degrees.

This time, the photos are brought to us by a joint effort from the Oviscori, the RSN, and the National Emergency Commission. The plane used to take the pictures was provided by the Air Surveillance Service of the Ministry of Security.

There are currently no signs that there will be another eruption but it seems that after the last one and frequent tremors there is some seal that broke and failed to reform, which is why the passage of internal fluids from the colossus is higher.
