The Nevado del Ruiz, the deadliest volcano in the Western Hemisphere, is about to erupt.

This volcano in Colombia has been showing signs of erupting. Part of it fractured and earthquakes are on the rise. The Colombian government issued an Orange Alert, stating eruption could be within weeks, or even days. Evacuations are taking place. Back in 1985, this same volcano caused a mud and debris flow (or lahar) that wiped out Armero, killing 23,000 people.

Today, they are desperately trying to avoid a repeat of that tragedy.
