Indonesia on February 19 raised flight warnings around the Mount Sinabung volcano on Sumatra island to their highest level after it sent a towering plume of ash more than 7 kilometres into the air, its biggest eruption this year.

Indonesia raises aviation warnings after Sinabung volcano erupts

The Bureau of Meteorology's Volcanic Ash Advisory Centre (VACC), in Australia's northern city of Darwin, issued maps showing an ash cloud heading in three directions from Sinabung, to the north, northwest and south-southeast.

Indonesian authorities also upgraded its Volcano Observatory Notice for Aviation (VONA) to red, its highest warning, and said the ash-cloud top had reached 7,276 metres.

Sinabung is about 75 km southwest of Kualanamu International Airport in Medan.

Nur Isnin Istianto, head of the regional airport authority, said Kutacane airport in Aceh province had been closed, but the wind direction allowed Kualanamu, Meulaboh and Silangit airports to remain open.

Sutopo Purwo Nugroho, a spokesman for Indonesia's Disaster Agency, said the eruption began on February 19 morning, accompanied by multiple earthquakes and showering surrounding villages with small rocks.

In five districts it became dark with a visibility of about 5 metres, he said.

No casualties were reported, but the agency urged the public to stay out of a 7-km exclusion zone around the crater, and watch for further warnings, which could cover floods.

Areas around the crater of the volcano, located about 1,900 km northwest of the capital of Jakarta have been off-limits for several years because of frequent volcanic activity.-VNA
