Flights disrupted due to Sinabung eruption
The volcanic ash spewed by Mount Sinabung in Karo regency, North Sumatra, disrupted a number of flights from Kuala Namu International Airport in Deli Serdang regency on Sunday.

In Bandung, the Center for Volcanology and Geological Hazard Mitigation (PVMBG) increased the volcano’s status to “awas” (beware), the highest level of the four-level alert system.

Affected airlines included Susi Air, which canceled five flights while Air Asia postponed its flight to Penang, Malaysia, citing safety reason as volcanic ash has reached the airport.

Susi Air operations manager Hadi Zulfadli said the flights included those from Kuala Namu to Simeulue and Singkil in Aceh and Aek Godang in Padang Sidempuan regency, North Sumatra. Also canceled was the flight from Banda Aceh to Kutacane.

Hadi said all the routes were unsafe because of the ash.

“The ash was quite thick. In the morning, all of our aircraft at Kuala Namu had been covered by ash,” he said on Sunday.

“It is dangerous if we keep flying so we decided to temporarily halt our operations.”

Hadi said flights would resume if the situation returned to a safe level.

Kuala Namu operations manager Ali Sofyan said that so far only Air Asia and Susi Air flights were affected by the volcanic ash.

“In general, the airport operations are normal. We found volcanic ash at a number of areas in the airport, such as the runway, but they have been cleared,” he said.

Mt. Sinabung erupted at about 9:45 p.m. Saturday, spewing volcanic ash as high as 10 kilometers.

The ash reached the provincial capital of Medan, some 80 kilometers away, for the first time since Sinabung erupted in 2010. This caused Medan residents to panic and become concerned about the ash, which started to fall at 11:30 p.m. The affected areas included Medan Tuntungan, Medan Johor, Medan Selayang and even as far as Belawan.

Meanwhile, Karo regency administration spokesman Jhonson Tarigan said evacuees had continued to arrive from various villages since the volcano erupted on Saturday.

“Currently there are 11,618 evacuees coming from 19 villages,” he said.

To anticipate a surge of evacuees, the regency had prepared 26 evacuation centers but only 22 are currently occupied.

North Sumatra Health Agency head Siti Hatati Surjantini called on residents in a number of regencies and cities around Mt. Sinabung to be vigilant. She asked residents to wear glasses and masks while outside and to reduce outdoor activities.

“I have sent a warning circular to the health agencies in Binjai, Dairi, Deli Serdang, Langkat, Medan, Pakpak Bharat and Serdang Bedagai to help monitor the eruption’s impact,” she said.

She added that her office had sent 180,000 masks, medicine and four tons of baby food to replenish health posts in Karo regency.

PVMBG head Hendrasto said that the wind was blowing toward Medan when Mt. Sinabung erupted, bringing ash to Medan.

He admitted that there was a lot of volcanic activity, hence the alert status increase as of 10 a.m. on Sunday.

“The volcanic activity is still fluctuating. It is accumulating so the pressure is high with high amounts of gas,” Hendrasto said on his decision to increase the alert level.

“Another indication is that we found volcanic rocks of between 3 and 4 centimeters in diameter within a 3 to 4 kilometer radius from the Sinabung crater.”

Hendrasto also recommended implementing an exclusion zone around the crater with a 5 kilometer radius as well as evacuating residents from four additional villages outside the 5-kilometer radius because the four villages were located in the mouth of the Mt. Sinabung crater,” he said.

National Disaster Management Agency (BNPB) spokesman Sutopo Purwo Nugroho estimated that another 15,000 villagers would come to evacuation centers following the status increase.

Vanochtend ook nog een paar erupties daar volgens mij.

Large explosion this morning
After a relatively calm period, a large vulcanian explosion occurred at the volcano this morning (04:30 GMT). VAAC Darwin reports an ash plume to 38,000 ft (12 km) altitude drifting 50 nautical miles to the NW.
The eruption was preceded by a smaller one at midnight (GMT) with an ash plume altitude of estimated 18,000 ft (5.5 km).
The volcano has been on red alert for 2 weeks and more than 17,000 people remain evacuated (for good reason!).

Paniek na hevige uitbarsting vulkaan Sinabung

Omwonenden van de zeer actieve Indonesische vulkaan Sinabung zijn zondag gevlucht nadat de berg nog heviger was uitgebarsten dan de afgelopen dagen. Zaterdag waren er liefst 50 erupties, maar zondag spuwde de berg zijn aswolken nog verder dan verwacht, meldden Indonesische media. .

Op motoren en in vrachtwagens sloegen de bewoners van de omliggende dorpen in paniek op de vlucht. De veiligheidszone rond de vulkaan op het eiland Sumatra is inmiddels 7 kilometer. De dorpen daarbinnen zijn bedekt met grijze as. De 2460 meter hoge vulkaan slingert as, puin en stenen de lucht in die in de verre omtrek neerkomen. Sinds november zijn al meer dan 20.000 omwonenden geëvacueerd.

22.000 evacuated
Indonesia's National Board for Disaster Management (BNPB) has reported the evacuation of 22,000 inhabitants located within a seven kilometer danger zone southeast of Mount Sinabung in Northern Sumatra, Indonesia, due to the risk of pyroclastic flows and hot gasses from the active volcano.

Mount Sinabung, which has erupted over a hundred times between Jan. 4 through the morning of Jan. 5 is spewing out a 4,000-meter high column of ash damaging property and crops and poisoning animals over a wide radius.

The volcano had lain dormant for nearly 400 years prior to an eruption in 2010. Thirty thousand people were displaced as a result of said eruption. BNPB has placed three more of Indonesia's 127 active volcanoes on high alert for possible eruptions.

Hmm daar iets ten oost en zuid van ligt een meer, genaamd lake toba. Dat was een supervulkaan die een enorme krater heeft achtergelaten. Staat sinabung in verbinding met die zelfde hotspot?

Eruption Sinabung intensifies
Hong Kong (CNN) -- A volcanic eruption in Indonesia that has displaced more than 22,000 people is intensifying, local authorities say.
Mount Sinabung, which began spewing gas in September after a three-year slumber, has erupted over 220 times this week.

The hot ashes and smoke have caused pyroclastic flows -- a fast-moving mass of gas and rocks -- to stretch to seven kilometers down the southeast slope of the 2,600 meter (8,530 foot) mountain in North Sumatra. Last week, flows reached three kilometers.

The local government is still able to cope with the disaster, and no casualties have been reported according to Sutopo Purwo Nugroho, spokesman for Indonesia's national agency for disaster management.
The government has evacuated more than 22,000 people to 34 temporary camps.
However one area, housing at least 1,000 residents, still lacks necessary provisions and shelter.
The displaced say they have urgent need for baby formula, clean water and gas, said local aid coordinator in Jambur Siabang-abang.

A national emergency hasn't been declared, but the government is prepared for the "worst case scenario."
In case of bigger eruptions, the danger zone would be extended to a radius of 10 kilometers from 5 to 7 kilometers currently.

If the zone is enlarged, Nugroho estimates that 59,000 people would have to be evacuated.
