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 :/

It is impossible to predict when a volcano's next eruptiopn will be.
The Nevado del Ruiz volcano is located on a destructive plate boundary whereby the dense, oceanic Nazca plate is being subducted under the less dense, continental South American plate. The melted rock from the Oceanic plate rises to the surface, the pressure builds until the magma erupts from the volcano. It is a composite or strato volcano meaning it is made up of layers of solidified lava and pyroclasic material.
