Nothing necessarily odd about that. Probably just too far out for the NORSAR data perhaps, mind you I would have thought USGS was using the same array.

I caught the 5.8 that just happened in Chile as it came off the seismos with my new tool set in near real time:

earthquake.usgs.gov...

But I am so clueless about counts yet, I could not tell whether this was a small, medium or large.

Growing pains.

Edit: Upgraded to 6.2

Strange that from the beginning of the year,all +5.5 have aftershocks.

What's up with this?

reply to post by Anmarie96


I don't have good feelings at all about the increasing magnitudes of the quakes in the Caribbean/DR here lately. That northern Caribbean Plate boundary is pretty darn overdue imo for a massive quake.

There were no immediate reports of damage or injuries.

Tremors were felt as far away as Cap Haitien in northern Haiti on Monday.

That sounds sophisticated and all, but to be honest, the more I read about how scientists calculate ground displacement, velocity and acceleration from counts, the less I want to be involved. It is a very complicated process, done on a per station basis, and requires in depth knowledge, per station, of that station's particular frequency response settings, calibration, filtering, and a whole lot more. God, growing pains suck. I don't know if I can handle this.

Hi ya'll!!!

I know I haven't been on in a while. Well..off and on pretty quick a lot of the time these days. Kids are keeping me pretty busy, not to mention work. ANYWAYS..... Just saw this article and was wondering what you guys think. I have no idea how credible this site is and like I said...just read the article myself.

No doubt there are precursors before an EQ. We have heard, read, and all that good jazzy junk. But...for someone to write and or issue a Mega Quake Warning....pretty uh... BOLD, but never the less I am glad to see someone putting it out there verses the alternative.

Tell me your thoughts....

www.eutimes.net...

A disturbing report prepared by the Schmidt Institute of Physics of the Earth (IPE) in Moscow that is circulating in the Kremlin today warns that the 6.2 magnitude earthquake that struck the Chiapas region of Mexico yesterday is a ‘potential precursor’ to a ‘megaquake’ of at least 7.5-8.3 expected to hit the US-Mexican Pacific coastline within the next fortnight (+/- 7 days). According to this IPE report, concerns were raised about this region after a 4.1 magnitude earthquake hit the Mexican Baja California peninsula on 18 January and emitted in the “4.433–4.498 micrometre range” “extreme” atmospheric temperature variations normally not associated with such a quake and that was verified yesterday as occurring again in Chiapas.

^Interesting link. A crap-tonne of people on youtube are issuing alerts for the western subduction zone, and another crap-tonne, since 2009, are having dreams of a megaquake and tsunami in that general area. I don't expect anyone to take any of that to heart, but with all things, we should be aware and on alert.

Perhaps Puterman could give his 2 cents? Which roughly adds up to a couple of dollars usually by how long and in-depth his posts are

Another interesting post:

The devastating earthquake that struck Japan in early 2011 was apparently preceded by small, repeating quakes that migrated slowly to where the disaster eventually took place, scientists now find. The magnitude 9.0 Tohoku-Oki temblor in March was the most powerful earthquake known to ever hit Japan and the fifth-most powerful quake ever recorded.

To find out more about why it happened — in the hopes of predicting any other such disaster — seismologists combed through records of seismic activity from before the rupture occurred. Their analysis identified small earthquakes that are normally obscured by overlapping seismic waves.

In the month before the Tohoku-Oki "megathrust" quake, the researchers found more than a thousand quakes migrated toward its hypocenter, the point where the quake's energy was released, at the rate of 1.2 to 62 miles (2 to 10 kilometers) per day. Their analysis suggests two sequences of faults slowly grinding against each other led to the initial rupture point of the disaster. The second of these sequences may have contributed enough stress to set off the main earthquake, they said.

They wish,wish they,but it wont happen because that region is subject to recent seismic stress discharge.
