Indonesia's Mount Sinabung erupted on Sunday, June 9th, spewing a spectacular column of ash and smoke some seven kilometres into the sky, Reuters has reported.
Residents shared images of the looming plume of grey ash rising over the volcano. A Volcano Observatory Notice for Aviation has already placed Sinabung on 'red' alert level -- its highest warning -- which generally means eruption is forthcoming.
Sutopo Purwo Nugroho, spokesperson for Indonesia's National Agency for Disaster Management (BNPB), confirmed on Twitter that Mount Sinabung sent out a column of ash about seven kilometres high at around 4.28pm local time (0928 GMT) on Sunday.
A thunderous roar was observed during the activity, he added. According to the disaster agency, no casualties were reported during the eruption.
The 2,460-metre (8,071-foot) tall volcano is among Indonesia's most active. When Sinabung erupted in 2014, more than a dozen people were killed and thousands were evacuated. Prior to recent activity, its last known eruption was four centuries ago.
