Big Shake
NOAA Tsunami warning for Indian ocean after another big quake (8.2?):
WARNING... THIS EARTHQUAKE HAS THE POTENTIAL TO GENERATE A WIDELY DESTRUCTIVE TSUNAMI IN THE OCEAN OR SEAS NEAR THE EARTHQUAKE.There have been recent warnings of risk for another big quake:
AUTHORITIES IN THOSE REGIONS SHOULD BE AWARE OF THIS POSSIBILITY
AND TAKE IMMEDIATE ACTION. THIS ACTION SHOULD INCLUDE EVACUATION
OF COASTS WITHIN A THOUSAND KILOMETERS OF THE EPICENTER AND CLOSE
MONITORING TO DETERMINE THE NEED FOR EVACUATION FURTHER AWAY.
THIS CENTER DOES NOT HAVE SEA LEVEL GAUGES OUTSIDE THE PACIFIC
SO WILL NOT BE ABLE TO DETECT OR MEASURE A TSUNAMI IF ONE WAS
GENERATED. AUTHORITIES CAN ASSUME THE DANGER HAS PASSED IF NO
TSUNAMI WAVES ARE OBSERVED IN THE REGION NEAR THE EPICENTER
WITHIN THREE HOURS OF THE EARTHQUAKE.
A team of seismologists led by John McCloskey at the University of Ulster in Northern Ireland, say more shaking could be in store.I sure hope they are working on the early warning system for the Indian Ocean area.
McCloskey and colleagues found that the so-called Sumatra-Andaman earthquake increased the stress on adjacent sections of the Sunda trench and the nearby Sumatra fault, which runs the length of Sumatra.
The team cannot predict when another earthquake will occur. But they say the increased stress, combined with historical evidence, raises the likelihood of another big quake in the region. History, they say, shows that one earthquake tends to follow another in the same region.
