WASHINGTON (AP) -- On Indonesia's Sumatra island, residents will likely never forget the deadly earthquake and tsunami that struck at the end of 2004.
But scientists now say many of them are in for another similar quake during their lifetimes.
American researchers are warning that another devastating quake along the coast of western Sumatra could occur within the next few decades -- with a loss of life and property equal to that of 2004.
The researchers, led by a Cal Tech scientist, report in the journal Science that they reached their conclusion by studying quake history in the region, and the sea-level changes recorded on corals.
They say the history is so variable, they can't make an exact forecast.
