Nevado del Ruiz Volcanic Eruption
25 November 2021
The Nevado del Ruiz Volcanic Eruption, also known as the Armero Tragedy, is considered as Colombia’s worst natural hazard-induced disaster which produced the deadliest lahar ever recorded. After 69 years of dormancy, the stratovolcano in Tolima, Colombia erupted in 13 November 1985 melting the mountain’s glaciers and sending lahars down its slopes at 60 kilometers per hour.
Funding challenges and security threats are hampering the monitoring of one of the world’s most volatile volcanoes – the Democratic Republic of Congo’s Mount Nyiragongo – even after a May eruption cost dozens of lives.
