The blaze that killed an Indonesian businesswoman who resided in Singapore broke out in a guest lodge - located on the west side of Kodiak Island off Alaska - where she was sleeping, according to a Alaska State Troopers' dispatch posted on Tuesday (June 7).

Ms Silvana Regina Sutanto, 59, had been fast asleep at about 4am last Thursday in the main guest cabin at the Spirit of Alaska Wilderness Lodge with her two children, identified as Shaun and Danielle Gozali, and another South Korean guest, Taeri Kim, the dispatch said.

Shaun, 30, and Ms Kim, 33, managed to escape through a window, while the lodge's owner pulled 22-year-old Danielle out of the burning building.

Ms Sutanto perished in the fire, which reportedly burnt through two buildings.

It was extinguished more than six hours later, with rescue efforts hampered by poor visibility.

The trooper dispatch said the three survivors were flown to Kodiak hospital via a US Coast Guard helicopter.

Ms Kim was treated at the hospital while Ms Sutanto's two children - both Indonesian nationals - were later transported to Seattle for further treatment.

The Straits Times reported on Tuesday that Ms Sutanto's husband, son and other relatives had flown to Alaska.

A director of five wellness and investment companies in Singapore, Ms Sutanto was also a nature lover and avid photographer who ran a photography blog where she had been documenting her travels to the Arctic Circle, Canada and Kenya.

Her last post on June 1 showed her and her daughter at the fishing lodge.

The cause of the fire remains under investigation.
