Hundreds of people still remain missing in Indonesia after two natural disasters struck the island. Monday's earthquake and Tsunami hit the remote communities west of Sumatra. At least 112 people are known to have died. Shortly afterwards, Indonesia's most active volcano mount Merapi in Central Java erupted, killing at least 25. Authorities there are still trying to move more than 10,000 villagers to refugee camps. Rescue teams are battling to reach hundreds of people believed to be missing a day after a tsunami struck small islands off the coast of Sumatra. Officials said a three metre high wave crashed into the Mentawai islands, leaving more than 100 people dead and 500 missing. Rescue efforts continue to be hampered by bad weather and aftershocks from the quake that caused the tsunami. Officials said Indonesian President Susilo Bambang Yudhoyono will fly back from a meeting with regional leaders in Vietnam to help deal with the tsunami aftermath. Meanwhile, the death toll from the eruption of Indonesia's Mount Merapi rose to 25 today. According to officials, a reporter and two volunteers were also killed. A volcanologist said although Merapi has not erupted again since Tuesday, people should remain in shelters. The 2,914-metre Mount Merapi, 400 kilometers east of Jakarta, is the most active of the 69 volcanoes with histories of eruptions in Indonesia.
