Some Canadians were trapped in Bali on Monday after Indonesian authorities ordered 100,000 people to flee from an erupting volcano that prompted the closure of the international airport.
Global Affairs Canada said 403 Canadians in Bali have registered with its Registration of Canadians Abroad service but there may be more.
"As registration is voluntary, this is not necessarily a complete picture of Canadians in the region," Global Affairs spokeswoman Brianne Maxwell said in an email.
Mount Agung has been spewing clouds of white and dark grey ash about 3,000 metres above its cone since the weekend and lava is welling in the crater, sometimes reflected as an orange-red glow in the ash plumes. Its explosions can be heard about 12 kilometres away.
The local airport authority said the closure for another 24 hours was required for safety reasons. Volcanic ash poses a deadly threat to aircraft, and ash from Agung is moving south-southwest toward the airport.
Richard Chang, a 31-year-old Canadian vacationing in the central part of the island with his fiancee and four friends, said his flight scheduled for Monday afternoon local time was cancelled.
The Mississauga, Ont.-native, who now lives in San Francisco, said they decided to move south to the area of Jimbaran to be close to the airport in case they need to make quick travel plans.
"We don't get the sense that the volcano is a danger to us," Chang said. "It's just the air traffic — there is a lot of ash and debris that is going into the air that is grounding flights."
Chang said arranging a flight from another airport has proven difficult, since many airlines fly out of Jakarta, about 26 hours by car 15 hours by boat.
He said he has a flight scheduled for Wednesday with Taiwanese airline EVA Air, but said he doesn't expect the airport to be open by then.
"We're assuming that the chances of us getting back to work are pretty much zero," Chang said. "So we're looking at just trying to get back in the safest, most guaranteed way before the end of the week or over the weekend."
Indonesia's National Disaster Mitigation Agency raised the volcano's alert to the highest level Monday and expanded an exclusion zone to 10 kilometres from the crater in places from the previous 7 1/2 kilometres. It said a larger eruption is possible, though a top government volcanologist has also said the volcano could continue for weeks at its current level of activity and not erupt explosively.
Agung's last major eruption in 1963 killed about 1,100 people.
Another Canadian stuck in Bali is Chantal Desjardins, a Montreal-based media personality and standup comic who was due to fly out Tuesday.
Desjardins said she was at a hotel about 70 kilometres away, and there was no word on evacuating her area.
She said that, according to her airline, the earliest she'll be able to leave is next Tuesday.
"We were supposed to leave tomorrow and we found out all of the airlines are cancelled and the first flight out is going to be December 5th," Desjardins said. "So my holiday just got extended by a little bit."
Bali is Indonesia's top tourist destination, with its gentle Hindu culture, surf beaches and lush green interior attracting about five million visitors a year.
Desjardins was within several kilometres of the volcano a few days ago.
"We saw some of the ashes coming up and we thought 'oh, this is really cool!'," she said. "Now, it's like, maybe I could have watched it on the news and it still could have been cool from another place."
Messages were sent to registered Canadians on Monday and the federal department's advisory for Indonesia was updated over the weekend.
Only one Canadian in the region has requested information, and Maxwell says they are ready to provide consular assistance as needed.
