Mexico's most dangerous active volcano has erupted 13 times in the past day, hurling columns of ash and smoke into the sky. The volcanic activity is disrupting flights in the area and prompted officials to warn people not to climb the volcano.
Popocatépetl has cycled through periods of activity and dormancy for the last half a million years, with its last major eruption taking place more than a thousand years ago. The current active phase began in 1994. Related: 'It is not very wise to spend the night in Grindavík': Iceland volcano gears up for another eruption
