Fun Facts about Nevado del Ruiz
Over at the more famous Nevado del Ruiz, seismicity has increased dramatically over the course of 2011 (the 20
year anniversary since its last eruption). During the month of August alone, almost 400 likely volcanically-related
earthquakes occurred at Ruiz
Sulfur dioxide measurements are listed as "moderate" but no signs of deformation have occurred at the volcano. All
that shaking means that Ruiz is also on yellow alert status, suggesting that an eruption might be in the cards
