Indonesia's most dangerous volcano is showing no signs of tiring, once again sending searing gas clouds and burning rocks down its scorched flanks.
Scientists warned that the slow eruption could continue for weeks, like a 'marathon, not a sprint.'
No casualties were reported in Mount Merapi's latest blasts Wednesday, which came as Indonesia struggled to respond to an earthquake-generated tsunami that devastated a remote chain of islands last week.
Thousands of people living along Merapi's slopes have been evacuated to government-run camps well away from the base.
Safari Dwiyono, a state volcanologist, said the new eruption started at 8:11am.
It spewed gas and rocks three miles (five kilometers) down the mountain's slopes.
