Dow Jones News Reports at 11:39 "DJ Singapore Official: 7.5 Quake Hits Sumatra - Kyodo"
No other reports yet.
Surfs up.
No warning in effect? Watch closely for this to change. This looks like de ja vu.
Wow, 8.5 is huge. I wonder which of the figures is correct.
8.2 earthquake ping!
And of course it's all Bush's fault!
The epicentral location is just where the quake started; the epicenter is at the southern limit of the December quake rupture; if the rupture propagated southwards, it's quite possible this is a rupture of the section that went in 1833 and had been heavily studied by Kerry Sieh at Caltech (and had been expected to rupture in a large quake even before the December quake.
And yes, it is one of the areas that stress actually increased after the December quake; the other area is on land in Northern Sumatra, a San Andreas like strike-slip fault.
Depth is hard to estimate, this was a bit deeper if the NEIC depth is accurate. It may or may not have produced a tsunami.
Also the magnitude, as always, might turn out to be bigger after more study. It's actually impossible to estimate the mag of a really big quake till after hours of data have been recorded.
"This looks like de ja vu..."
Yeah..... all over again... :(
sw
THIS EARTHQUAKE IS LOCATED OUTSIDE THE PACIFIC. NO TSUNAMI THREAT
EXISTS TO COASTLINES IN THE PACIFIC.
WARNING... THIS EARTHQUAKE HAS THE POTENTIAL TO GENERATE A WIDELY
DESTRUCTIVE TSUNAMI IN THE OCEAN OR SEAS NEAR THE EARTHQUAKE.
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.
Those folks can't catch a break! Prayers sent!
December quake: 3.3N 95.8E
March quake: 2.9N 97.02E
Very close.
but if you have no radio, you dont get the warning. poor people.
Pacific Tsunami Center Just issued one for all coast line within 1000 kilometers of the epicenter.
FNC claiming an 8.2 per the USGS...
The bulletin with no warning is for the US Pacific coastline.
Ah, thank you (I think). :-)
8.5 is big, the last one was a 9.0.
That would put it just off the west coast near the island of Pulau?
If the ground shook, I bet they are in a panic.
