The causes of the Nevado del Ruiz eruptions
1) location (intersection of four fault lines -- as if one fault line wasn't bad enough)
2) occurrence of small earthquakes
3) spewing of gas and steam
4) phreatic eruptions
5) pyroclastic eruptions
In consequence, the town of Armero was destroyed, and thousands of people were killed or left homeless.
BY AISHA ARIFNo, the eruption of Nevado del Ruiz in 1985 was mainly an explosive eruption that generated pyroclastic flows and lahars by melting snow and ice on the volcano's summit. There was no significant lava eruption during this event.
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.
Yes. Nevado Del Ruiz is a volcano known for its 1985 eruption which killed well over 20,000 people.
I don't know Stratovolcano
No, Nevado del Ruiz is not a cinder cone volcano. It is a stratovolcano, which is a large, steep-sided volcano built up of many layers of hardened lava, tephra, pumice, and volcanic ash.
It is impossible to predict when a volcano's next eruptiopn will be.

Ruiz, Nevado del. Ruiz is the northern-most historically active volcano in South America (4.9N, 75.3W).
From all the research I've done I have figured out that it had something to do with the shifting of the tectonic plate it sits on but I'm afraid that's about as detailed as it gets :/
