MOUNT MERAPI, Indonesia (AP) - Indonesia is struggling to deal with this week's dual disasters, a tsunami blamed for 413 deaths, and a volcano that has killed 36.
      
The military has forced villagers off the slopes of Mount Merapi. The volcano has unleashed its most powerful explosion yet, sending clouds of gray ash cascading down its slopes.
      
The eruption temporarily forced the closure of the airport (Yogyakarta), 12 miles away. An airport official blamed poor visibility and heavy ash on a runway.
      
Despite earlier hopes that Merapi's activity might be waning, scientists are now warning the worst may be yet to come.
      
Hundreds of miles to the west, relief workers say 135 people missing since a tsunami hit a remote island chain have been found alive or have returned to their villages. There are still 163 missing from the tsunami.
      
Many tsunami survivors are still waiting for food and other supplies. Deliveries have been delayed because aircraft have been grounded by violent storms.
