A giant column of volcanic ash spews from the summit of Mount Sinabung reaching at least 2,000 meters (6,600 feet) during its eruption at 6:30 am (2330 GMT) on August 30, 2010 seen from Tanah Karo in North Sumatra. Airlines on August 30 were warned to avoid remote Mount Sinabung in northern Sumatra as the volcano spewed a vast cloud of smoke and ash high into the air for a second day after springing to life for the first time in four centuries on August 29.
