Sinabung, Indonesia : the potential for pyroclastic flows remained great.

Mount Sinabung in Karo regency, North Sumatra, erupted forcefully once again on Wednesday and may threaten the opening of the Lake Toba Festival by Tourism Minister Arief Yahya in Berastagi, also in Karo, slated for Thursday. No casualties were reported following the eruption, but pyroclastic flows drifting to the southeast affected a number of villages that have long been abandoned by residents.

The current wind direction is directed to the southwest, but if it blows to the east the Lake Toba Festival will be disrupted as the spread of ash would reach Berastagi, » Mt. Sinabung Observation Station staff member Deri Hidayat told The Jakarta Post.Deri said the volcano discharged the clouds at 1:47 a.m. and 9:28 a.m. He added the pyroclastic clouds, which drifted as far as 3.5 kilometers, affected Bekerah and Simacem villages.

He said both villages had long been left empty as they were inside a designated danger zone.Deri added that Mt. Sinabung had also emitted volcanic ash to a height of 2,000 meters toward the southwest. He said the spread of ash could disrupt the Lake Toba Festival if the wind changed direction in coming days.He said volcanic activity could increase within the week, adding that the volcano could discharge a bigger volume of pyroclastic flows and ash. « The biggest eruption took place on Tuesday, when the volcano discharged pyroclastic clouds 13 times, compared to only twice today, » said Deri.

According to him, the potential for pyroclastic flows remained great due to a lava dome buildup on the southeastern section of the peak.Deri said the lava dome could collapse anytime and trigger huge pyroclastic flows.Consequently, added Deri, his office had recommended that the regional administration evacuate human settlements within the danger zone.
