A large eruption of Galeras volcano stratovolcano in southern Colombia, occurred November 20, 2009.
The volcano has triggered several alerts during the last ten years when eruptions of explosive nature, were observed. The eruption of the November 20, 2009, forced local authorities to declare an alert, calling on thousands of area residents to evacuate.
Locals have been asked to put masks to avoid inhaling the ash generated by the volcano.
