The Kuala Namu International Airport (KNIA) administrator has
warned airlines traveling to North Sumatra to avoid flying over the
Mount Sinabung area for safety reasons.
KNIA operational manager Ali Sofyan said a number of airline
companies had been warned following the eruption of Mt. Sinabung in Karo
regency, North Sumatra. Ali added that the warning was especially aimed
at low-flying airliners, such as Susi Air and Wings Air, and
helicopters.
“They have been advised not to pass the navigation area near Mt.
Sinabung. For the time being, the path is unsafe for flying due to very
limited visibility caused by volcanic ash,” Ali said on Wednesday.
Ali said he had advised airlines flying to Nias Island, North
Sumatra, and Simeuleu Island in Aceh to reroute their flights to avoid
the effects of the eruption.
KNIA air traffic controller Susanto said that changing flight paths
was aimed at avoiding volcanic ash that normally followed the wind
direction. “If the ash blows eastward, then the flight path will be
diverted to the west around 8 kilometers from the mountain and at
altitudes of between 7,000 and 9,000 feet,” Susanto said, adding that
low-flying aircraft flew at an altitude of over 4,000 feet and a
distance of 4 kilometers from Mt. Sinabung.
KNIA has remained open since the eruption. “Everything remains normal
because the volcanic ash from Mt. Sinabung has yet to affect operations
at KNIA,” he said.
After first erupting on Sunday, Mt. Sinabung erupted again on Tuesday
and on Wednesday and discharged huge volumes of volcanic material. A
staff member at the Mt. Sinabung observation post, Ahmad Nabawi,
confirmed that the volcano erupted again on Wednesday at 2:30 a.m.
“This is the third eruption. More eruptions are likely, but we don’t
know when,” said Nabawi, adding that the third eruption sent volcanic
ash up to 1,500 meters into the air.
Nabawi added that the volcanic ash blew eastward early on Wednesday.
“The ash spread until Berastagi, and even reached Sibolangit and Pancur Batu in Deli Serdang regency,” said Nabawi.
The Meteorology, Climatology and Geophysical Agency (BMKG) Data and
Information Center head at KNIA, Mega Sirait, said the ash reached
10,000 feet high. “We advise airlines to divert their planes from
passing the Mount Sinabung area because it is very dangerous,” said
Mega, adding that wind velocity at altitudes of between 5,000 and 12,000
feet around the Mount Sinabung area currently reached up to 15 knots.
According to Mega, the speed is regarded as normal.
