CNE declares green warning for Rincon de la Vieja volcano

The National Emergency Commission (CNE) has declared a green alert due to increased activity at the Rincon de la Vieja volcano. Five districts in particular are subject to this warning: Dos Rios, Aguas Claras (Upala), Mayorga, Cañas Dulces and Curubande (Liberia).

The decision was announced by the CNE on Sunday, May 5, at around 10:00 a.m. The institution noted that there has been a significant increase in volcanic seismicity since April 17, which has also increased in recent days.

“As Rincon de la Vieja is a very dynamic system, current conditions may change quickly in the short or medium term. Therefore, it is always recommended to be careful and avoid entering the areas with the greatest volcanic risk, that is, the summit of the volcano and the rivers that drain along the northern slope, where lahars (mud flows) generally flow down,” the CNE explained.

According to the CNE, seismic energies are the highest in five years and both the extent of the base of the volcano edifice and the elevation at the summit have disappeared.

The National Emergency Commission issued a series of measures to the emergency committees and called on the public to follow the recommendations. The emergency committees will be responsible for following up the ash and gas fall in the affected areas and will remain active and monitor the most risky sectors in the mentioned districts.

“The population, especially those living in risk areas, is asked to remain informed and only adhere to the messages disseminated by official national, regional and municipal authorities,” the CNE stated.

Experts also advise avoiding unnecessary exposure to ashfall and the possibility of lahars in the rivers draining towards the districts of Upala (Dos Ríos and Aguas Claras), covering the respiratory tract and eyes in case of exposure and official websites for information to consult.

On the other hand, according to OVSICORI, the Poas volcano has reported strong degassing with a decrease in ashfall. Specialists will continue to monitor activity on both volcanoes and make recommendations if necessary.
