Volcano experts from the Red Sismológica Nacional were at the Volcán Rincón de la Vieja Thursday to study the site where neighbors reported an eruption between 4 and 4:30 a.m.
The Red Sismológica said that it appears that the eruption was contained inside the volcano’s crater. An earthquake sensor 3.5 kilometers from the crater says that there were other eruptions. One was Sunday at 16 minutes after midnight and one was Monday 46
minutes after midnight. They were small, said the Red Sismológica.
The last major eruption at the mountain was in September when material came out of the crater after explosions and polluted nearby streams.
Parque Nacional Rincón de la Vieja is about 25 kilometers or about 15.5 miles northeast of Liberia in Guanacaste. The volcano is 1,916 meters high or about 6,286 feet. It is part of the mountain range that is the spine of the country.
