🌋💧 THE 1985 NEVADO DEL RUIZ ERUPTION - THE ARMERO LAHAR CATASTROPHE | 23,000+ Lives Lost 🌋💧 November 13, 1985, 11:25 PM - A relatively small VEI-3 eruption of Nevado del Ruiz in Colombia melted the summit glacier, creating massive lahars (volcanic mudflows) that raced down river valleys at 60 km/h. A 40-meter wall of mud engulfed the town of Armero 74 km away, burying 23,000+ people alive in one of the deadliest volcanic disasters in history. Despite warnings, inadequate evacuation and communication failures turned a predictable disaster into a preventable tragedy that revolutionized lahar hazard awareness worldwide. 📊 ARMERO LAHAR CATASTROPHE FACTS: • 23,000+ deaths (75% of Armero population buried alive) • VEI-3 eruption - relatively small but deadly due to glacier melt • 40-meter lahar wall traveled 74 km from summit • 60 km/h lahar speed - mud reached Armero in 2.5 hours • 50 million cubic meters of mud, rock, and debris • 13 Colombian towns and villages affected • Warning systems in place but not activated properly • International media coverage shocked world • Omayra Sánchez: 13-year-old trapped for 60 hours symbolized tragedy • Legacy: Lahar hazard mapping and mandatory evacuation protocols globally
