Recent eruptions and ongoing monitoring prompt warnings from Costa Rican authorities.
The Poás Volcano, located in Alajuela,
Costa Rica, has exhibited heightened activity, with the most recent eruption occurring at 7:10 a.m. on March 30, 2025. Experts from the Volcanological and Seismological Observatory of
Costa Rica (Ovsicori) reported that the plume from this eruption reached an altitude of approximately 200 meters above the crater and dispersed southwest, as analyzed through webcam data.
In addition to this morning's eruption, another significant eruption was recorded on the night of March 29, 2025, at 8:51 p.m., where a volcanic column ascended to 1,000 meters.
Following this event, the eruptive activity subsided slightly but remained characterized by more frequent explosions, with plumes continuing to reach heights of up to 200 meters.
The Poás Volcano has been monitored closely due to its frequent eruptions since November 2024, and it is currently classified at Level 3 on the Ovsicori's alert scale, where Level 4 indicates a dangerous eruption.
Authorities continue to emphasize that an eruptive process is ongoing, showing signs of explosions and ash emissions.
Since late November, the volcano has demonstrated consistent eruptive manifestations.
Experts suggest that there is a possibility of a significant increase in eruptive activity, potentially due to deeper magma or magmatic fluids moving toward the surface.
Alternatively, it is also possible that the internal fluids of the volcano will gradually dissipate, leading to a decline in activity without a major eruption.
Ovsicori has reiterated the unpredictability of natural events, urging continued caution among the public.
