The impact of the eruption. Magma rose upwards inside the Ruiz

summit. As the peak became warmer, snow and ice melted causing a series of minor mudflows. Melted water, snow and ice ran down the mountainside into the river. The lagunillas River flooded. As the snow and ice melted, ash from previous eruptions was turned into mud.

how did people try to make this never happen again?

Following the 1885 eruption the ‘Volcano Disaster Assistance Program’ (VDAP) was set up. The VDAP aims to reduce the number of fatalities caused by volcano eruptions in developing countries and limiting the economic loss. Many of the people living in Armero region are employed in agriculture. Because of the ash deposited by volcano eruptions, the soil around the Armero region is very fertile.
