OVSICORI-UNA reported that seismic tremor has decreased over the past days. There is tendency to inflation of the volcano edifice. ... [more]
Thursday, Feb 13, 2020
OVSICORI-UNA report that there is currently a stable fluctuation pattern of seismic activity at the volcano. There is continued inflation but not a significant amount. Carbon dioxide/Sulfur dioxide (CO 2 / SO 2) ratios remains stable with the exception of a peak on February 9. There is almost no Hydrogen sulfide (H 2 S). Sulfur dioxide emissions significantly increased over the weekend (February 8-9). The crater lake level has also decreased. [more]
Thursday, Feb 13, 2020
OVSICORI-UNA report that no ash emissions was detected from the volcano. Seismicity is of a stable amount. Carbon dioxide/Sulfur dioxide (CO 2 / SO 2) and Hydrogen sulfide/Sulfur dioxide (H 2 S / SO 2) ratios remain within a normal range. Sulfur dioxide emissions was measured at an average of 100 tonnes/day. Crater depth was measured at 140 m, compared to 220 m in 2019. This shallowing of the crater is due to “frequent collapses of the internal walls.” [more]

Arenal |Barva |Irazu |Miravalles |Orosí |Platanar |Poas |Rincón de la Vieja |Tenorio |Turrialba
Costa Rica is a small country but has a lot of active volcanoes aligned like pearls on a chain, caused by the NE subduction of the Pacific tectonic plate under the Carribean plate. Among the country's most active volcanoes are Arenal, Poás and Irazú volcanoes.
Arenal
(Stratovolcano)
Arenal volcano seen from Rio CalienteArenal, a major tourist attraction in Costa Rica, is one of the most active volcanoes of Central America. Since a major eruption in 1968, it has been in near-continuous activity building a lava dome and displaying mild explosive activity from the summit crater. [more]

Irazu
(Stratovolcano)
Irazú (3432 m) immediately east of the capital San José is Costa Rica's highest and one of its most active volcanoes. Tephra fall (ash) during the last major eruption of Irazú in 1963-65 caused heavy damage to infrastructure and life in San José and its surroundings. [more]
