One of the world's deadliest volcanos has lain dormant since it last erupted in 1985, but a surge in seismic activity indicates it could awaken in the 'coming days.'
Colombia's Nevado del Ruiz registered an unbelievable 6,000 earthquakes per day last week, leading officials to raise the alert to the second highest scale and evacuate more than 2,500 families in the area.
Some 57,000 people live in the volcano's hazard zone, which is spread across parts of six provinces, according to Colombia's Geological Service (CGS).
CGS believes last week's earthquakes are due to magma moving through the fault system, setting the stage for what could be Nevado del Ruiz's next deadly eruption.
CGS reported that increased seismic activity was first observed last month, with 6,500 earthquakes on March 28 to 11,000 earthquakes on March 29.
Activity began to slow on Sunday, but the volcano spewed a 3,000-foot column of ash the same day.

Volcanoes block sunlight and kill crops. Google 1816 year without a summer. Had a bad volcano in Russia a few days ago.
