Volcano Type- strata volcano
location- colombia
- The Colombian volcano Nevado del Ruiz is an active stratovolcano with a history of generating deadly volcanic mudflows lahars- from relatively small-volume eruptions.
- In 1595, a lahar swept down the valleys of the River Guali and the River Lagunillas, killing 636 people.
- In 1845, an immense lahar flooded the upper valley of the River Lagunillas, killing over 1000 people.
- It continued for 70 kilometers downstream before spreading across a plain in the lower valley floor.
- The young village of Armero was built directly on top of the 1845 mudflow deposit.
- Over the ensuing years, Armero grew into a vibrant town with over 27,000 residents.
- On November 13, 1985, history repeated itself for the third time in 400 years, with another eruption and another deadly lahar racing down the River Lagunillas.
- This time, over 23,000 people were killed, including most of the residents of Armero. With proper planning, this tragedy could have been averted.
- over the last week the volcano has rumbeld back into life as can be seen on the web-Cams on the BBC page : http://www.bbc.co.uk/programmes/p00tmqd6/features/webcams
- what could this mean for the people who live below the volcano?.. it remains to be seen... however hopefully due to the increase in knowlage of the volcano and increased monitoring the effects will be mitigated and the damages decreased!
