1985
Volcano erupts in Colombia and buries nearby towns
On this day in 1985, a volcano erupts in Colombia, killing well
over 20,000 people as nearby towns are buried in mud, ice and
lava.
The Nevado del Ruiz volcano is situated in the north-central part
of Colombia. Over the centuries, various eruptions caused the
formation of large mudflows in the valleys beneath the volcano.
When the Nevado del Ruiz went an extended period of time without
erupting, people began to build towns over the mudflow areas and
glacial ice built up near the volcano's crater.
In last few months of 1984, activity picked up at the volcano.
Multiple tremors were recorded and geologists from around the
world traveled to Colombia to observe the situation. The
following November, an eruption of steam and ash caused ice,
rocks and mud to cascade down the mountain. Scientists, believing
that a full-blown eruption was possible, recommended evacuating
the area. Their concerns, however, were largely ignored.
On the afternoon of November 13, a major eruption occurred. Ash
was sent 30 miles into the air, but still, possibly believing
they had more time, few residents evacuated. Later that evening
into the morning of the November 14, there were several more
powerful eruptions. Lava flowed out of the crater, melting the
glacial ice surrounding it and causing massive mudslides.
The town of Chinchina was first to be hit. Approximately 1,100
people were killed when a mudslide overwhelmed the village. The
worst scene of destruction was the city of Armero. The wave of
mud, rock and ice was nearly 100 feet high as it barreled down on
the city. Although it could be heard for a full 30 minutes before
it struck, there was little the residents could do to avoid it.
Further, many radio reports were instructing the residents to
stay in their homes. Close to 20,000 people were buried and
killed by the slide.
Overall, the best estimate is that 25,000 lives were claimed by
the eruption of the Nevado del Ruiz volcano.
