>> At the Roa Roa Hotel in Palu, the search for survivors of Indonesia's earthquake is a race against time. Very few survivors have been pulled out alive four days after the quake and tsunami as the death toll rises well above 1,000 people. Rescue is using acoustic detectors on Tuesday to listen for signs of life.
But landslides and broken roads and bridges have slowed the search says Reuters correspondent Kanupriya Kapoor who's there.>> So we're at a hotel where about 50 people are believed to be trapped inside. Authorities have been working on this since Friday. But some of the heavy machinery has only arrived on Monday, about 24 hours ago, because a lot of the land access to Palu, which is one of the worst hit cities, has been blocked.
>> A paragliding team who were in town for a competition are clinging to hopes they'll see some of their team mates alive again. The rescuers have pulled several of their bodies from the rubble>> We remain optimistic that they're alive even though scientifically speaking by this time after such an event the body's ability to endure is minimal.
>> As rescuers reach remote districts, the scale of the devastation is emerging. This is, or was, nearby Mamboro. In some areas the quake caused liquefaction, where solid ground became fluid. Shifting dirt appears to have completely erased at least one neighborhood. Authorities dug a mass grave for victims on Sulawesi island.
They say most of the bodies are unclaimed. The survivors, there's been little help so far, prompting a scramble for what's left. Looters stripping shops and taking petrol as police looked on.>> There are a lot of shortages of basic supplies like fuel and food and water. And that is causing a lot of the survivors of this disaster to get a little bit desperate.
And there have been reports of looting, so now we're seeing armed police guarding things like banks and gas stations in the city.>> Thousands have thronged to Palu's tiny damaged airport hoping to get onto the few aircraft evacuating residents. But most of the 60,000 or so people now homeless are stuck in open air camps with no where to go.
