At least 320 people were confirmed dead in the Nias Island over an earthquake measuring 8.5at Richter scale northwest to the Sumatra Island late Monday, an officer in charge of emergency relief affairs for the Nias Island said Tuesday.

　　There are more bodies under the debris, which cannot be removed immediately for lack of equipment, he said, adding Indonesian Vice President Jusuf Kalla said that the final casualty could reach 2,000.

　　The quake also damaged the roads, bridges and airport, and one can reach there only by ship or helicopter, he said.

　　"The airport can be landed by small plane only," he said, adding that 10 trucks of relief materials like bed sheets will be shipped to the island Tuesday night and medical staff are on their way too.
