Indonesia’s Metro TV also had reported that 12 survivors were spotted by an initial search team but rescuers could not reach them because of heavy rains and hilly terrain.
Al Jazeera's correspondent in Jakarta learnt that doctors at the hospital nearest the crash site were told to expect 12 survivors. But the country's aviation chief said the government could not confirm that there were any survivors.
The aircraft had been carrying 96 passengers, including seven children and four infants, as well as six crew members.
It was on a domestic flight from Java island to Sulawesi when it lost contact with air traffic control late on Monday, about an hour before it was due to land, in very bad weather.
Hundreds of people gathered at Manado airport, the aircraft's destination. Some collapsed when they heard that 90 people had died, while others demanded information from the Adam Air office there, witnesses said.
Adam Air, one of about a dozen budget airlines in the world's fourth-most populous nation, operates 19 Boeing 737 jets. It started in December 2003 and serves dozens of domestic routes in Indonesia and also flies to Singapore.

On Tuesday, a Lion Air passenger jet skidded on a runway at the Pattimura airport in Ambon, eastern Indonesia, in heavy rain.
State news agency Antara said none of the passengers was reported hurt and the aircraft was not damaged.
Air travel in Indonesia, home to 220 million people, has grown substantially since the liberalisation of the airline industry after the Asian financial crisis in the late 1990s.
