Colombians flee volcano eruption
Thousands evacuated after Nevado del Huila volcano shoots out hot ash and gas.
The latest eruption was preceded by seismic rumblings which began on April 8.
The Nevado del Huila, which is topped with a crown of ice, is Colombia’s third-highest peak.
In 1985, the town of Armero was destroyed and 25,000 people were killed when another volcano, the Nevado del Ruiz, exploded and set off a series of mudslides.
