Costa Rica News – The evaporation of rainwater in La Fortuna de San Carlos has caused smoke in the Arenal Volcano on Monday, according to the Volcanological and Seismological Observatory of Costa Rica.
The experts explained that hot material inside the colossus can take up to years to cool.
This means that when it comes in contact with rain, a column of steam is produced, like the one observed Monday morning.
This occurrence was higher than on other occasions because of the humid atmosphere and the calm wind and clear sky. This led to the column being more vertical. While the last eruptive event was seven years ago, the temperature recorded inside is still at about 230 degrees centigrade.
To be considered active, a volcano must increase seismicity, present magmatic gases and increase the temperature and acidity of thermal waters.
Experts predict the Arenal volcano will, at some point, resume activity.
