The Nevado del Ruiz located in Colombia is showing increased signs of eruption. This is a concern because, in 1985, the Nevado’s eruption caused avalanches of earth and rock fragments that covered settlements and killed at least 25,000 people.

Colombia already plans to evacuate everybody that lives 15 kilometers away from the Nevado del Ruiz, with high monitoring of the volcano and more evacuations possible in the coming days.

Colombia has already raised the Volcano Alert Level to orange which means that they’re steadily watching the volcano and are on high alert. Last week, the volcano has been registered an average of 6,000 earthquakes each day. This is most likely due to magma moving through the main fault system in the volcano.

The eruption is uncertain. An orange alert doesn’t mean the volcano will erupt due to the fact that there have been 18 orange alerts since 1985 and no major eruptions have happened since. So it is just a matter of time until it is figured out what the outcome of this event will be and it will be impossible to predict when the eruption is going to happen.
