(AP) -- Chilean officials ordered most residents already evacuated from homes near an erupting volcano to stay in shelters and with family and friends Sunday due to the threat of deadly landslides. The ash spread across the Pacific, prompting authorities to suspend flights in Australia and New Zealand.

The Cordon Caulle volcano's activity had diminished, but there was still a threat of deadly containing mud and water as well as rocks and ash thrown from the volcano, Chile's National Geology and Mines Service said in a statement.

About 4,000 Chileans have been evacuated since the volcano began erupting June 4. The agency said the area north of the volcano is in danger of landslides and avalanches.

Thousands of passengers in Australia and New Zealand were affected as the approached the two countries. Australia's national carrier, Qantas Airways, grounded flights within the country and in New Zealand.

National carrier Air New Zealand has not canceled or delayed any flights yet, instead choosing to adjust routes and altitudes to ensure aircraft remain clear of any ash, company spokeswoman Tracy Mills said. But the company was continually assessing the situation and could be forced to suspend service later Monday, Mills said.

Despite the cloud's expansion overnight, Virgin Australia started flying out of Melbourne, Tasmania and New Zealand again Monday morning with a reduced schedule. More than two dozen Virgin flights were still suspended, and about 4,000 to 6,000 passengers stranded, said company spokeswoman Melissa Thomson.

Qantas, meanwhile, canceled more flights in and out of Melbourne, saying it would reassess at midday Monday. All flights to and from Tasmania and New Zealand were grounded.

The of ash could disrupt travel for the next several days and could reach the Australian capital, Canberra, on Monday afternoon, according to Airservices Australia.

hovering over the Argentine capital of Buenos Aires and the nearby Uruguayan capital of Montevideo forced officials there to cancel flights late last week. Air traffic began returning to normal Friday night and was operating normally early Sunday.

But late Sunday, conditions began to worsen again in Buenos Aires and authorities decided to "limit air operations" at Jorge Newbery airport in the Argentine capital, a National Civilian Aviation Administration statement said.

Several airports in the nearby southern Argentine region of Patagonia remained closed. Sunday's winds began blowing ashes in a northeasterly direction, toward the Patagonian cities of Villa La Angostura and San Martin de los Andes, vulcanologist Hugo Moreno said.

Haroldo Lebed, executive secretary of Argentina's agricultural emergency and disaster agency, said that authorities are going to declare a national emergency to get financial aid to affected producers.

Moreno said that scientists discovered during a flyover of the Saturday that it was not spewing material through a 3-mile-long (5-kilometer-long) fissure, but through a crater measuring 980 feet to 1,300 feet (300 meters to 400 meters) in diameter.

Chile has more than 3,000 volcanoes along its Andean spine, and 500 of these are considered geologically active. About 60 Of these have erupted in the past 450 years.

The Cordon Caulle is located 620 miles (1,000 kilometers) south of the Chilean capital, Santiago.
