Green Alert Issued for Rincón de la Vieja Volcano
Costa Rica's National Emergency Commission (CNE) has placed five communities near Rincón de la Vieja under a preventive green alert after more than 100 eruptions during July and August, including the year's most energetic eruption on Monday. The alert covers Dos Ríos and Aguas Claras in Upala, and Mayorga, Cañas Dulces, and Curubandé in Liberia. It is precautionary and does not mean residents are being evacuated. Officials are warning people to stay away from rivers that could carry fast-moving lahars (mixtures of water, mud, and volcanic debris) and to keep livestock from drinking from them. If ash falls, limit outdoor exposure and wear a mask. The national park has not automatically closed, but SINAC can restrict access on short notice, so check the latest conditions before visiting.
