Authorities in Indonesia fear that the death toll will continue to rise, after two natural disasters this week. A small tsunami formed off the coast of Sumatra on Monday. And, on Tuesday, hundreds of miles away, the country's most active volcano, Mount Merapi, erupted.
The Associated Press reports that the ten-foot tsunami was triggered by a powerful earthquake more than 10 miles below the sea floor, along the same fault line that caused a devastating tsunami that killed 230,000 people in 2004.
On Thursday, authorities said 33 people had been killed by the volcanic eruption, and at least 370 were killed by the tsunami, with hundreds more missing, according to The AP.
Because of its location in the "Ring of Fire," Indonesia has been hit by a number of devastating natural disasters. According to the U.S. Geological Survey, about 90 percent of the word's earthquakes take place in the "Ring of Fire."
