Breaking: Earthquake Sumatra, Indonesia Mag 7.8

I'll admit, there being absolutely no aftershocks is a bit odd. There are still aftershocks happening Baja California, yet none in Indonesia?

Thanks for the update. I was just teasing you

But yeah it takes time for us to get good information, I was about to freak out with you too. haha.

Oh, my wife's friend informed us that he believes Baja is on the direct other side of the earth. The word he used was Antipodal.

They are on nearly exact opposite sides of the earth. Almost exactly.

So how can this be? That the two quakes are antipodal within just 30-40hours timespan?

I doubt it is a coincidence.

Oh, I know you were teasing.... But seriously, if you have a link listing any aftershocks, can ya paste a link??

I completely agree about the quakes being opposite.....first thing I noticed when I looked at the map. The whole tug-pull thingy.

The longer we go without any aftershocks increases the likelyhood that something bigger is still lurking.

Is that so? What data do you have to support this claim? I'm not doubting it, but I can't remember any instances in the past where a big earthquake like this came, there were no aftershocks, and then a bigger one came after that.

How about 8.0+? (I had it handy)

(Actually, magnitude scales are logarithmic, not exponential. Not exactly the same.)


[edit on 4/6/2010 by Phage]

Logarithmic (had to google it) is the rarity of Earthquakes, but not the power, right? If I am understanding correctly, earthquake power is exponential in terms of tnt vs magnitude.

Being in the first 1/3rd of the year, one 8.0 is pretty bad, and 7.8 is nearing that.

I may try to make a 7.5 graph if I can figure out how.

Yup, just added. They must be relying on only 'siesmologist' reviewed data right now, so it's taking longer?

As to the question about something bigger coming, I read something to that affect some time, but I couldn't tell you where. Don't take my mumblings as scientific proof...I'm too lazy right now (and limited on time) to look it up, but perhaps someone with more knowledge could chime in. Maybe I'm off the mark on it.

USGS seem way behind reporting on anything outside the USA/Mexico at the moment - they still haven't reported the 5.1 off Western Turkey that occurred 10 mins after the Indonesian 7.8, as reported on RSOE EDIS, assuming that is correct:

The antipode of the Indonesian earthquake would be somewhere off the coast of Colombia.

hmmm alot of news of earthquakes.... volcanoes.......

where is planet x again?

he New Madrid fault line is next... That will definatly give everyone something to rant about...

There has been 3 aftershocks so far that is what the UK news has said.
Lets see what happens at this rate the chances of an earthquake each month on the news for the rest of the years looks possible.

Well it can just stop that nonsense right now

The big one there in 2004 gave us a 4 1/2 foot wave in the harbor, washed some people off the breakwater, don't want anything bigger thanx

I would hazard to guess the leaps and bounds we've had in technology in the last decade. Information can be shared much easier now, so we hear about these things more often.

reply to post by Phlynx

No. The magnitude scale (the energy of the earthquake) is a logarithmic scale.

Here's that 7.5+ chart.

Thank you for addressing this Phage.

The website you linked looks very cool, I will be playing with it a lot!

TY again sir!
