JAKARTA, Indonesia (September 30, 2009)--Thousands of people were reported trapped Wednesday under collapsed buildings including two hospitals in Indonesia after a powerful earthquake.

At least 75 people were killed on Sumatra, and the death toll is expected to be sharply higher than that.

Because of heavy rain and a power outage, authorities aren't sure of the extent of the damage and casualties.

Officials said the quake triggered a landslide that cut off land transport to the area closest to the epicenter.

The quake was along the same fault line that spawned the 2004 Indian Ocean tsunami.
