Why did Nevado del Ruiz erupt?!
On 13th November 1985, 20,000 people were feared
dead after Nevado del Ruiz, a long dormant
volcano which stands at 18,000 ft , in the Andes
in Western Columbia erupted. Causing mud and
water to flood the town of Armero. Dismembered
bodies floated in the floodwater stained with
sulphur. Armero was hard to reach for rescuers
after taking 12 hours to get through. Columbias
civil defence unit (C.D.U) later confimed that 7
villages had also been destroyed!

Armeros population of 28,000 were devastated
before dawn.The death toll reached the highest
since in Martinique in 1902.The eruption caused
an ice pack and snow to melt on the peak. 2 hours
later, this sparked an avalanche.85 of Armero
was swept away by mud rocks and water.The
volcano had blown smoke 26,000 feet into the air,
causing some aircrafts visibility to drop and
land in another city.

What Devastation Was Caused By The Eruption?!
Colombia is one of the most dangerous countries
in the world!! Following the mudslide, many
people were trapped in mud, water and debris that
was left behind. Thousands later died! When the
Ruiz erupted, there was not a team of mobile
volcanologists that could rush to this
emergency! The mud which travelled at 80km per
hour, covered Armero to the height of 8 METRES!

Following the mudslide many people were trapped
in the mud, water and debris that was left
behind. Thousands later died!! Because of the
ash deposited by the volcano, the soil around the
Armero region is very fertile. Following the 1985
eruption the VOLCANO DISASTER ASSISTANCE PROGRAM
(VDAP)was set up!It aims to reduce the number of
fatalities caused by volcanic eruptions in
developing countries and limiting the economic
loss.

• The problem is, that tragedy which should have
  been avoided or predicted, because the volcano
  was active since one year. The authorities did
  not want to panic the people living in this area
  and studies have already been done, in October
  1985, geologists published a hazard map of the
  area, 100 of probability that Amero will be on
  the way of mudflows. The government did not want
  to alarm the populations. The geologists who
  visited the volcano 2 days before did not
  recommend an evacuation. But 23,000 people died.
