Indonesian authorities have issued warnings to airlines about the danger of flying over the central part of Sumatra Island in connection with the eruption of the Mount Kerinci, Xinhua reported.
At 12:48 am local time, the Kerinci volcano threw an ash column to a height of 800m.
"It is better (for planes) to avoid the pathway around Mount Kerinci because the volcano would see another eruption at any time and volcanic ash spewed into the air would endanger planes," the statement from the energy and mineral resources ministry said.
