SAN
FRANCISCO — Some of the biggest coral die-offs in recorded history happened in
2004 and 2005, after massive earthquakes in Sumatra, off the coast of
Indonesia.
Now,
researchers report similar evidence of ancient massive
coral kills on Simeulue Island, caused by ancient earthquakes. An
analysis of the fossil coral beds provides clues to the history of
megaearthquakes in the region, and could help predict future quakes,
researchers said Monday (Dec. 3) at the annual meeting of the American
Geophysical Union.
Simeulue
Island lies off the west coast of Sumatra, Indonesia, where the 2004 earthquake
stopped and the 2005 shaker began to rip the fault apart. Earthquakes of this
size may break a fault for hundreds of miles, but they do have a starting and
stopping point.
