A volcano spewed more hot ash and lava on a tiny Indonesian island Monday after causing six deaths over the weekend. More than 500 Palua island residents who had earlier refused to leave the 3-kilometer (1.9-mile) exclusion zone around Mount Rokatenda have been evacuated to the neighboring island of Flores, said Mutiara Mauboi, an official at the command post, AP reported. The bodies of two children who were among six people killed by lava as they slept early Saturday have not been recovered. "There is no more searching for the victims. The main activity now is evacuation," Mauboi said from her office in the town of Maumere. "All of the residents in eight villages on Palua have to be moved gradually." The eruptions were smaller Monday but the potential danger was high because the volcano continues to release hot gas clouds, said government volcanologist Surono, who uses only one name like many Indonesians. Molten lava and ash have covered most of Palue, an island in East Nusa Tenggara province with only a 4-kilometer radius. "Mount Rokatenda remains on high alert," Surono said. "There has been no significant decline in activity." About a quarter of Palua's 12,000 people moved to Flores after the volcano began erupting last October, said Tini Thadeus, head of the local disaster agency, adding the government has agreed to build new houses for the displaced. The six victims this weekend were among residents who had refused to leave last year when the safety zone was established, he said, adding that many who stayed believed in old customs that requires their presence to keep lava from destroying villages, Thadeus said. Among the dead was a 58-year-old woman, the grandmother of the two children.
