The latest eruptions formed an ash and vapor crest of some 9,800 feet (3 kilometers) over the crater, evident from various places in the Central Valley.

OVSICORI estimates that ash could reach communities in the Northwest area of the crater. A region that holds at least fifteen small towns.

The National Seismological Network posted a video made of pictures sent to its social media profiles:

The National Emergency Commission (CNE) issued a Green (Informative) Alert on Thursday following an explosion Wednesday night at Poás Volcano.

The tourist entrance to the Poás Volcano National Park is closed indefinitely.

The Volcanological and Seismological Observatory of Costa Rica (OVSICORI) reported that the explosion happened at around 6:30 p.m. and thrown rocks, vapor, fumes, and water into the air and towards the southwest of the crater,

Water and sediments fell on the close by rivers: Agrio, Gata and Desagüe rivers causing a flash flood on the latter.

CNE Operations Director Walter Fonseca said in a news release that there is a possibility of similar events, so officials recommend that people stay away from these rivers and nearby areas.


Businesses in areas surrounding the volcano, located 47 kilometers northwest of San José, are open and working, as usual, the agency noted.

Visitors were forced to evacuate the popular national park last Sunday as a preventive measure due to an increase in the emanation of gasses from the crater.


Camino Travel has no passengers affected by these events. We will continue updating the news until the situation comes to calm.
