The National University’s Volcanological and Seismological Observatory of Costa Rica (OVSICORI) reported last Thursday that Rincón de la Vieja Volcano, in Guanacaste Mountain Range, has increased vapor activity and explosions.
Big explosions were recorded on Wednesday at 1:54 p.m., and on Thursday a high column of ash and steam was seen on top of the main crater.
Local residents told OVSICORI that ash had fallen on the roofs of their homes in an area six kilometers around the volcano, mainly in communities north of the crater in Upala and Buenos Aires.
Volcanologist Javier Pacheco on Thursday said activity of the volcano had decreased in the past 15 years, but evidently there is an increase in deposits of volcanic material in the crater.

Ash, mud and vapor explosions intensified last year, but inspections in recent months found that material mostly fell in the area surrounding the crater. Some of this material also fell on rivers located north of the volcano, mostly carried by rain during the past rainy season, Pacheco said.
OVSICORI experts recommend that visitors avoid getting too close to the volcano’s crater. The region is a popular destination for tourists attracted by the volcano as well as several lodging options including hot springs resorts.
