Nevado Del Ruiz case study

Lars formed of water, Ice, volcanic rock and clay were created, and flowed down the river valleys at speeds of kept, growing to around four times their original size. The Lars reached the city of Rammer around 2 hours after the eruption. The eruption was relatively small, measuring 3 on the Rector scale Impacts: The Lars that hit the town of Rammer killed three quarters of the 28,700 inhabitants.

They lasted approximately two hours, burying 85% of the town in mud.

Another lair killed 1800 people and destroyed 400 homes in the town of Cinchona. Hundreds of people died from infections after the disaster, and many survivors faced concerns of disease such as yellow fever caused by mud getting into wounds. The loss of life was exacerbated by the unpreserved of local people – although warnings were put in place, many people did not receive them or could not understand them, and the Colombian government accused scientists of scaremongering.

Response and Management: An international aid effort was set up to respond to the disaster, with the US government spending $1 million in aid. Rescue workers and medical supplies were sent to the area, although rescue efforts were made difficult by collapsed bridges, and thick, soft mud. The eruption occurred at the same time as the 1985 Mexico City earthquake, meaning the numbers of people available to help was limited.

At the mime there was guerrilla warfare in the capital city, so the army and government were not available.
