87 Questions
Why did the nevado del ruiz happen?
The Nevado del Ruiz eruption in 1985 was primarily caused by the interaction of tectonic plate movements beneath the Andes Mountains, leading to increased volcanic activity. The eruption was a result of the melting of ice and snow on the volcano's summit, which created lahars—destructive volcanic mudflows. These lahars devastated the nearby town of Armero, resulting in significant loss of life and property. The event highlighted the importance of monitoring volcanic activity to mitigate risks to surrounding communities.
How many houses were destroyed in the Nevado del Ruiz eruption?
The Nevado del Ruiz eruption on November 13, 1985, caused significant destruction, particularly in the town of Armero, Colombia. It is estimated that around 25,000 homes were destroyed due to the volcanic activity and the resulting lahars (volcanic mudflows). The disaster led to a tragic loss of life and highlighted the vulnerability of communities near active volcanoes.
How may people did the Nevado del ruiz eruption kill?
Nevado del Ruiz killed about 23000 people in 1985 in November 13th.
Only about 5000 out of the original 28000 people living in the nearby city of Amero survived

What are the names of four tectonic plates located near the Nevado del Ruiz volcano?
Nevado del Ruiz is on the South American Plate and is the result of the Nazca plate subducting under it. The Cocos and Caribbean plates are not far away.
What type of magma does nevado del ruiz have?
Nevado del Ruiz is a stratovolcano, so the composition of the magma likely varies over time. The tragic eruption of 1985 involved magma of andesite or dacite composition.
Why did people live so near the nevado del ruiz volcano?
People lived near Nevado del Ruiz volcano due to its fertile soil, suitable for agriculture, and the economic opportunities provided by the surrounding areas. Additionally, the volcano's past eruptions were not recent or well-documented, leading to a false sense of security about its potential hazards.
Why were there more deaths in Nevada del Ruiz than in Mount St Helens?
There were two main reasons. First, with Mount St Helens, the people were given adequate warning while they were not with Nevado del Ruiz. Second, when Nevado del Ruiz erupted, several towns were in the paths of major lahars.
