Recent volcanic eruptions have made headlines in different parts of the world — from the deadly Mount Dukono eruption in Indonesia and Mayon Volcano blanketing Philippine towns in ash to lava streams and fountains at Kīlauea in Hawaii and and intermittent eruptive activity at Piton de la Fournaise in Réunion Island. Did you know that volcanic eruptions can trigger multiple hazards beyond lava flows? Ashfall, mudflows, poor air quality, and even climate impacts can affect communities far from the eruption site. That’s why #EarlyWarnings matter. Volcanic ash models rely on weather data such as wind field, humidity, pressure. Integrating geohazards into weather and climate services can help communities better prepare for and respond to volcanic risks. 📸 This photo of Pacaya Volcano in Guatemala captured by Cindy Lorenzo is one of the winners of the WMO 2026 calendar competition.
