The official death toll in Wednesday's massive earthquake in the Indonesian Island of Sumatra has risen to 777. However, UN humanitarian chief John Holmes said on Thursday that the latest figures suggest the death toll has risen already to 1,100 and may go higher given the number of injured and those trapped in collapsed buildings. The brunt of 7.6-magnitude earthquake, which originated in the sea off- Sumatra island, appeared to have been borne by the city of Padang, where a government official said most the deaths occurred.<br/><br/>The region was jolted by another powerful earthquake on Thursday, causing damage but no reported fatalities. More than 500 buildings including hotels, schools, hospitals and a mall were destroyed or damaged in Padang and rescue work is continuing.<br/>
