Officials In Indonesia Warn Mt. Sinabung’s Volcanic Eruption Could Continue Almost Indefinitely

An observation team says that Mount Sinabung in Karo regency, North Sumatra, is likely to continue erupting for quite some time following an increase in seismic activity on Monday. As of 12 p.m. Monday, Mt. Sinabung had 148 temblors comprising 83 short-period quakes, 34 low-frequency and 31 mixed tremors. Observation team member Arif Cahyo said Mt. Sinabung’s tectonic quakes showed that a large volume of magma was present, indicating that the volcano would continue to erupt for a long time. “We cannot determine how long Mt. Sinabung will continue to erupt, but if we observe the increase in seismic activity, it will definite be a long time,” Arif told The Jakarta Post on Monday. Arif said that Mt. Sinabung was still erupting and emitting pyroclastic flows and volcanic ash sporadically. He said the volcano had emitted pyroclastic clouds twice on Sunday and three times on Monday. “Until Monday noon, the volcano discharged pyroclastic flows three times that drifted as far as 2,500 meters to the south, while volcanic ash drifted up to 1,500 meters to the east,” said Arif, who voiced fear that Berastagi city would be covered by ash that had been drifting east for the past two days.
