This is because now there are much better warning systems in place so that scientists can inform residents of impending danger. If Nevado del Ruiz does erupt, the situation will be vastly different from 1985. "It's just really difficult to know what's going to happen but at this point, we do know that there are signs of unrest."īrand said similar activity was observed in 1984 but it was almost a year before there was a significant eruption. "We could see a dramatic increase in the earthquakes and swelling of the volcano and the gases coming out, which may indicate a significant eruption, or it might just die off," Brand said. It is not certain that an eruption will occur-this is difficult to predict with any volcano-but Nevado del Ruiz is displaying some telltale signs. Despite scientists warning them to evacuate, many have stayed as their livelihood depends on the fertile land. The area around the volcano is home to many farmers and their families. Even a relatively small eruption could be enough to melt the glacier with potentially devastating consequences. On November 13, 1985, the volcano produced an extremely explosive eruption that resulted in the deaths of more than 20,000 people in the town of Armero in what was the second-deadliest volcanic eruption of the 20th century.įor this reason, there is added concern about the volcano and its seismic activity.
The Nevado del Ruiz volcano was responsible for what is known as the Armero tragedy. Lahars are destructive mud flows from the slopes of a volcano that can be devastating. Read more Video of Florida tornado flipping car in air viewed 1 million times
