Indonesia thinks it is a 7.4

That is a large differance . Is that a WOW or WTF

yep, I watched that sukka come in on GEE. Didn't register that hot in microns/sec on the AU-Manu and AU-RABU stations...But I knew it was big from the shape and duration. It's shaking up the world as we speak...

Definitely a WTF - I just headlined it as such.

Original depth was shown as 130 now EMSC shows it at 10 and USGS has just come in at 6.6 Mag 21 km depth.

Don't suppose they will bother with a tsunami warning for that. They have not so far.

Still falls inside a WTF

USGS now showing a 6.6 AND a 7.2

Not quite sure if this is an error. Investigating.

edit2:
I managed to save the map and the phase data before it got deleted.
Did it happen or not?

Appears to be a smaller quake right on top of the station...wow 2 mm/sec, but no duration much...

Two,according to this.

reply to post by muzzy


I have to admit that blowing this up it does look like one. PMG.IU.00.BHZ.2010.272

Very difficult to say. The trace is steady until a second or two after 17:14 (green line) when the P hits and then the S appear to be about 17:16:30. I don't see a second signal one minute later. I am going to see if I can pull a SAC file on this one.

Looks like a single to me. Sound coming shortly

reply to post by PuterMan


USGS is now saying the first one was a 6.2 - Still preliminary reports. Looking forward to the sound file Puterman

reply to post by Anmarie96


Sounds like one to me.

Sound file About 282 Kb @ 16000 Hz because lower speeds you just cannot hear it at all. Original Hz was 40 so this is 400 x faster. The second sound comes at 17:21 in the file according to my calculator so is NOT a second earthquake as the P would have to be immediately after the first. You would hear a fast double bump.

reply to post by PuterMan


Judging from what I saw, I say one, and only a 6.2 if that. A 7+ would have rocked those stations AU.MANU and AU.RABL. And sorry, but it just wasn't that strong. You know I like to take screens of the bigger ones, and 7+ would have run into the high 800 microns/s or into mm/s on those stations. It's why I didn't take a screenie.

ETA: lol, check out this supposed 7.2 on REV:

That tiny little bump? No chance that was anywhere near a 7. Watch, betcha they revise it down to the single 6.2 or less.

And that's from AU.MTN, which is closer than KAPI to the epicenter.

reply to post by PuterMan


I don't know Puterman - I heard 2 bumps then a roll which was separte = 3 sounds altogether = bump, bump then roll. At least that is what it sounds like on these speakers
