3. What Happened?
On the 13th November 1985 the Nevado del Ruiz erupted. This caused a huge mudflow where it descended down the mountain towards the town of Armero. The mudflow reached a massive 30 meters high and was travelling at 80 km per hour. The river Lagunillas Flooded and burst its banks because of the snow and ice that had ran down the side of the mountain. The mudflow hit the town of Armero at 11pm.
By the morning a layer of mud 8 meters thick covered Armero and the surrounding areas. This mudflow also hit 7 other surrounding villages and destroyed them all.

5. MAP!
Nevado del Ruiz has 5 other volcanoes in a line under it and this is what it looks like.

6. How Volcanoes work!
Volcanoes work by the magma chamber erupting and sending lava, ash, lava bombs, steam, gas and dust in to the air. This lava melted the snow and ice on the top of the Nevado del Ruiz causing the water to rush down the volcano and caused the huge mudflow!

Some good work and presentation Darryl but maybe this is a little short on the facts – more facts and information about the eruption needed A2
