Nevado del Ruiz The "Sleeping Lion"
NEVADO DEL RUIZ IS IN COLUMBIA, S AMERICA 5,321 METRES HIGH WITH SNOW ON SUMMIT HEIGHEST ACTIVE VOLCANO IN THE WORLD Nevado del RuizThe Facts
Pyroclastic flows melt the snow and ice Lahars run down the river valleys 50m deep mixture of mud, water and rock
Lahars follow the rivers River banks overflow
Lahars flood the fields and villages Houses are washed away
Reasons why there was so much damage and why so many people died • Armero was built on old mud flows from previous eruptions and was in danger from the volcano • The Lahars moved very quickly and were very powerful so that they destroyed everything • The eruption and lahars happened at night when people were in bed sleeping • The people did not heed the warnings to evacuate from the town and villages earlier that day • Rescue was very difficult with all the roads and bridges damaged or covered in the floods
Mr Manson says . . . • Some very good work and presentation Philip. A good mix of pictures, writing and explanation. Well done! Keep this up! • A1
