8.9 quake in Tonga?!

Isn't that the European agency that's always overestimating by a couple of points?

what does ML magnitude mean??

I don't know . . . anyone?

yet?

Did it break in half or what?

Here we go. Hang on!!!

ML is local magnitude.

"The Richter magnitude scale, also known as the local magnitude (ML) scale, assigns a single number to quantify the amount of seismic energy released by an earthquake. It is a base-10 logarithmic scale obtained by calculating the logarithm of the combined horizontal amplitude of the largest displacement from zero on a Wood–Anderson torsion seismometer output. So, for example, an earthquake that measures 5.0 on the Richter scale has a shaking amplitude 10 times larger than one that measures 4.0. The effective limit of measurement for local magnitude ML is about 6.8."

At a depth of 2km, an 8.9 would probably rip the surface to shreds. Im guessing it was the Fiji quakes earlier that set the seismographs off?

Just pulled this info:

Why Are There So Many Earthquake Magnitude Scales?

Earthquake size, as measured by the Richter Scale, is a well-known, but not well understood, concept. What is even less well understood is the proliferation of magnitude scales and their relation to Richter's original magnitude scale. Richter's magnitude scale was first created for measuring the size of earthquakes occurring in southern California, using relatively high-frequency data from nearby seismograph stations. This magnitude scale was referred to as ML, with the L standing for local.

As more seismograph stations were installed around the world, it became apparent that the method developed by Richter was strictly valid only for certain frequency and distance ranges. In order to take advantage of the growing number of globally distributed seismograph stations, new magnitude scales that are an extension of Richter's original idea were developed. These include body-wave magnitude, “mb,” and surface-wave magnitude, “MS.” Each is valid for a particular frequency range and type of seismic signal. In its range of validity each is equivalent to the Richter magnitude.

Because of the limitations of all three magnitude scales—ML, mb, and MS—a new, more uniformly applicable extension of the magnitude scale, known as moment magnitude, or “MW,” was developed. In particular, for very large earthquakes moment magnitude gives the most reliable estimate of earthquake size. New techniques that take advantage of modern telecommunications have recently been implemented, allowing reporting agencies to obtain rapid estimates of moment magnitude for significant earthquakes. So nowadays, when most seismologists announce a magnitude number, they are rarely referring to the Richter Scale.

and the USGS is well known for UNDERestimating by a few points

It doesn't make it invalid as of yet....

Excellent information, but is there any info that compares the new readings to that of the Richter? So that we can discern the differences?

If true thats a big fucka.

This is more to date I think

Okay, so-- if I'm reading it correct, based on the above information, the Tonga 8.9 reading is based on the Richter/ML ????

Your link is to the public consumption page of emsc, which only lists the epicenter quake value (the 7.1 in Fiji). The non-public page (my link) lists all sensor readings, which often helps to show the range of a quake. It is possible that the Tonga reading was simply a mistake, but that is still to be determined ... (perhaps there is no one left in Tonga to say one way or another!)

nice dig soledad. it is volleyball season after all.

Not seeing it on any of the links now

he's comin

who's that asshole?

He is the god that brings in this new age by shakin the ground that we walk upon.

Oh really. I suppose you know his name and origins also. I am all ears.

Heads for the hills, MOFOS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!


:5:

king poppycock.

B’olon Yookte tis the name mayan is the game.

Wrong. This illustration is a bad copy of a carving in Central Mexico (nowhere near Mayan lands) and it represents the solar god Tonatiuh in his human aspect, Nanahuatzin. Nanahuatzin was a humble man who became the fifth sun in a ceremony at Teotihuacan.

If there were one deity in the pantheon of gods that represents earthquakes, it would actually be a goddess, not a male god.

Bolon means the number 9 in the Yucatecan language, and has the connotation of sacredness. Yokte should be Yokche. It is a particular kind of tree. The translation would be Great Tree.

This illustration is not even in the style of anything Mayan. Another example of people trying to appropriate cultures they do not understand.

I disagree on your choice of tonatiuh and since no image of B'olon Yookte exist and the ones that do are not at all like this one.

This image does convey the message of the god that comes and shakes the earth. and he is comein. I also disagree about the female and male aspect and where you think the mayan lands were.

Since neither of us where there it is just an opinion.

So I still don't see anything on USGS. India just had a 6.2, though.

But no such god exists in Yucatecan lore nor in the lore of the nations in Chiapas, which are Mayan lands. I have lived there and worked with Mayan peoples. My wife is a full blooded Yucatecan Maya and speaks two dialects. My children are half Mayan. You can disagree all you like about the male and female aspects, but the truth is that the Mexican nations of central Mexico (where the 5th sun legend originated AFTER the height of the Mayan civilization) did not have one god of earthquakes. The fifth age was to end with earthquakes. This is "Aztec" lore. Not Mayan. The name of the 5th sun is Nahui Ollin, which means 4 movement.

You can disagree all you like. There are several details on the illustration that are distinctively related to the solar god. You can see these same elements on the solar calendar stone.
