We are providing this important update regarding the activity of the Poás Volcano, a remarkable natural wonder that may be part of your planned itinerary with us in Costa Rica.

As of 2:30 PM on March 31st, 2025, the National Commission for Risk Prevention and Emergency Attention (CNE) has raised the alert level for the Poás Volcano National Park and the Toro Amarillo district of Sarchí (including the river basins of Desagüe and Agrio) to ORANGE ALERT.

What Does This Mean?

This decision was made following reports from the Technical Advisory Committee (CAT) in Volcanology and Seismology, which includes experts from OVSICORI-UNA, RSN (ICE-UCR), and the LAQAT-UNA laboratory, along with authorities from SINAC-MINAE. They have observed a significant increase in the volcano’s activity, including:

• Significant and ongoing emission of ash and gases.
• Frequent energetic eruptions over the preceding weekend, some exceeding the crater’s height.
• Near-continuous, low-amplitude eruptions, accompanied by nearby seismic activity, ground deformation, and other indicators of an active volcano.

Which Areas Are Affected?

• ORANGE ALERT:
  • Poás Volcano National Park (with increased security measures).
  • Toro Amarillo district of the Sarchí canton (including the Desagüe and Agrio river basins).
• GREEN ALERT (remains in place for the following cantons):
  • Alajuela
  • Poás
  • Grecia
  • Sarchí (excluding the Toro Amarillo district)
  • Naranjo
  • Río Cuarto
