    Does anyone know what the last one's magnitude was that caused that huge tsunami on christmas?

    Between 9 and 9.3 form what I can see online, this new one could be lethal.

    There are actually a lot of pieces that have to slot into place for a disaster the size of the 2004 one. The depth and location of the quake is as important as the magnitude. An 8M earthquake in the wrong spot could cause far more devastation than a 9M earthquake in a different location, even though the 9M is 32 times more powerful.

    This one is roughly as shallow as the 2004 one, but significantly weaker. At least there's serious early warning this time though, even if a tsunami doesn't appear.

    The 9 is 32 times greater than an 8. That's scary. Does it go up by 32 times for each magnitude?

    2004 quake caused a massive ridge on the sea bed to displace a massive amount of water, size of the quake won't matter a whole lot

    Roughly. It's a logarithmic scale, so a 9 is 1000 times more powerful than a 7, and 1 million times more powerful than a five. Each jump on the scale is an increase in power of 31.62 times.

    Sorry - hadn't seen this thread when I opened a new one.

    I'm on the east coast of India and we felt the earthquake from here. Everyone ran out of buildings into the street and looked very panicked. Only tremors here though but still scary.

    I'd say it won't be anything like 2004. What does an earthquake feel like anyway?

    Just got tremors here... things shook for a minute but that was it. It was nothing like in Banda Aceh I'm sure.

    Sister in law just posted this status update to her facebook page!
    wow earthquake...strong..

    She lives in Northern Sumatra (about 100 k from Banda Aceh)

    Hopefully its not going to prove to be something worthy of posting to the "DUMB FACEBOOK STATUS UPDATES" thread

    and great to know that people can always find time to keep their FB updated for the rest of us.............i can just picture her running for higher ground, tapping furiuosly on her iphone.

    Seeks unlikely to be a tsunami as the crust has shifted horizontally rather then vertically.

    Lots of folk predicted this on FB and youtube. Seems like everyone knows about the 188 cycle but anyone that matters.

    Guy states 9th 10th or 11th there will be a 7.5 +.

    pacific tsunami warning centre
    http://ptwc.weather.gov/ptwc/text.php?id=indian.TSUIOX.2012.04.11.1014
    EVALUATION

    SEA LEVEL READINGS INDICATE A TSUNAMI WAS GENERATED. IT MAY
    ALREADY HAVE BEEN DESTRUCTIVE ALONG SOME COASTS.

    BASED ON THESE DATA THE THREAT CONTINUES FOR ALL COASTAL AREAS OF
    THE INDIAN OCEAN. FOR THOSE AREAS - WHEN NO MAJOR WAVES HAVE
    OCCURRED FOR AT LEAST TWO HOURS AFTER THE ESTIMATED ARRIVAL TIME
    OR DAMAGING WAVES HAVE NOT OCCURRED FOR AT LEAST TWO HOURS THEN
    LOCAL AUTHORITIES CAN ASSUME THE THREAT IS PASSED. DANGER TO
    BOATS AND COASTAL STRUCTURES CAN CONTINUE FOR SEVERAL HOURS DUE
    TO RAPID CURRENTS. AS LOCAL CONDITIONS CAN CAUSE A WIDE
    VARIATION IN TSUNAMI WAVE ACTION THE ALL CLEAR DETERMINATION MUST
    BE MADE BY LOCAL AUTHORITIES.

    ESTIMATED INITIAL TSUNAMI WAVE ARRIVAL TIMES AT FORECAST POINTS
    WITHIN THE WARNING AND WATCH AREAS ARE GIVEN BELOW. ACTUAL
    ARRIVAL TIMES MAY DIFFER AND THE INITIAL WAVE MAY NOT BE THE
    LARGEST. A TSUNAMI IS A SERIES OF WAVES AND THE TIME BETWEEN
    SUCCESSIVE WAVES CAN BE FIVE MINUTES TO ONE HOUR.

    yeah 33ft of a change so that was massive!

    its weird that this *may* not cause a massive tsunami but a smaller aftershock could create one due to a ground shift after the original quake weakened the ground.

    Fingers crossed neither of these circumstances happen
