Volcano Poás Erupts, Sending Ash Plume 1,000 Meters High
A significant ash eruption occurred at Costa Rica's Poás Volcano, with activity noted since March.
On the morning of June 10, 2023, the Poás Volcano in Costa Rica exhibited significant volcanic activity, erupting ash and generating a plume that reached approximately 1,000 meters in height above the crater.
The eruption commenced at 3:40 A.M. local time and continued into the early morning hours, according to the latest report from the Observatorio Vulcanológico y Sismológico de Costa Rica (Ovsicori-UNA).
The ash plume, characterized by a gray color and a moderate load of ash, dispersed towards the west at an approximate speed of 17.9 kilometers per hour, as per data from the Instituto Meteorológico Nacional.
The event was confirmed through monitoring via web cameras, seismic tremor recordings, and direct observations by staff from the RED SISMOLÓGICA NACIONAL (RSN).
To date, there have been no reports of ash fallout affecting surrounding communities.
The Poás Volcano, which stands at an elevation of 2,687 meters above sea level, has been in an eruptive phase since March 23, 2023. During this period, it has shown a continuous emission of magmatic gases, primarily rich in water vapor, sulfur dioxide (SO₂), and aerosols, alongside discrete events of ash expulsion.
The volcanic activity is particularly concentrated in Boca A of the crater, where temperatures have been recorded between 400 to 500 degrees Celsius, as determined by analysis of infrared satellite imagery.
Scientific authorities are maintaining ongoing monitoring of the volcano and advise caution to visitors and residents in the vicinity.
