Local military colonel Ida Dewa Agung Hadisaputra said soldiers had now been given orders to shoot people spotted stealing from shops.
"If there is looting again, we will quickly fire a warning shot and then shoot to immobilise," he said.
"They tried to loot on the first day, when gasoline... and water were not available. Stores were also closed.
"That kind of situation caused them to loot."
"We could tolerate it (looting) on the first and second day because they needed those things," he continued. "But on the third day, they started looting things like electronic equipment."
He said every vehicle carrying supplies would now be guarded by five armed soldiers.
