Nevado del Ruiz is a stratovolcano located in the central part of Colombia. It is considered one of the most active and dangerous volcanoes in the country, with a history of generating destructive lahars and pyroclastic flows. In this article, we will delve into the facts and information about the Nevado del Ruiz volcano.

Geographical Location and Composition

Nevado del Ruiz is situated in the Andes mountain range, approximately 129 km (80 mi) from the capital city of Bogotá. It is part of the Los Nevados National Natural Park, which is home to other volcanic peaks and glaciers. The volcano’s composition consists of layers of lava, volcanic ash, and pyroclastic rocks, which have built up over approximately two million years of volcanic activity.

Types of Eruptions and Hazards

The Nevado del Ruiz volcano has a history of generating explosive eruptions, ranging from Vulcanian to Plinian. The eruption in 1985 caused the deadliest lahar in recorded history, known as the Armero tragedy. The lahar, which was triggered by the melting of snow and ice on the volcano’s summit during the eruption, swept away the town of Armero and claimed the lives of over 23,000 people.

Current Status and Risk Assessment

The Volcanic and Seismic Observatory of Manizales constantly monitors the Nevado del Ruiz volcano. The current status of the volcano is an orange alert due to an increase in seismic activity, which indicates a heightened risk of volcanic activity. Up to 500,000 people could be at risk from lahars and other hazards in the event of future eruptions.

Nearby Town and National Park

The town closest to Nevado del Ruiz is Herveo, which is situated on a mesa overlooking the volcano. The English translation of La Mesa de Herveo is the Mesa of Herveo. Los Nevados National Natural Park, which encompasses the volcano and surrounding peaks, is a popular destination for hikers and nature enthusiasts.
