Quake Watch 2013

There is a way to prove it, but IRIS is down and I cannot get any seismograms and/or data files.

Once it is back i will take a look.

THANKS MUCH for the China info. A lot of my heart is still with the Chinese people and culture.

The buildings--particularly in rural areas are not very quake resistant at all.

Adobe construction is common even in the cities in many areas.

And, even in Taiwan, some of the . . . qualities . . . of construction depended on what folks could get away with in terms of cutting corners.

Thankfully, in China . . . construction folks, contractors, engineers . . . can suffer great punishment--up to and including death--for neglect and corruption resulting in many quake deaths.

Though I wonder how many are actually deterred from such activities by such punishments. Sigh.


Interesting times we live in . . . for sure.

Thanks for all you do on such scores.

I enjoy your reports, Puterman, especially the average days between events data. Thanks.

This Alaska quake was very shallow (unless it gets revised ), only 400 meters.

Thanks,
wait until I get to doing the historic data back to 1831BC, Taiwan is obliterated with icons, you can't see any towns or features on the map unless you zoom into almost ground level, its a wonder anyone survived!

So the question is will it be reduced tomorrow, or on the 18th March. I go for the 18th. Wow, downgraded already!!!. My apologies USGS.

I doubt that 10km will be the true depth but even 40km seems very shallow for this region?

Tsunami alerts?

somehow the whole region between papua newguinea and vanuatu seems really unstable the last months, I wonder what is going on there

Whilst IRD can be a bit wild in their magnitudes they do have one which I found on the seismograms which is NOT mentioned by any of the main agencies:

IRD Earthquake Details

Date Magn. Localisation
09/03/2013 13:37:04 4.8 Vanuatu Islands

I don't think they are wrong on this one, in fact they may be light.

The trouble is that other ones they say are Vanuatu I cannot see on the seismogram for SANVU, for example

IRD Earthquake Details
Date Magn. Localisation
09/03/2013 10:46:25 3.9 Vanuatu Islands

The same day but is not visible

My point is that a quake that was almost certainly a 4.5 min and probably a 4.8, was not picked up by anyone else.

I remember the Santa Cruz Islands zone doing the same just before a very large quake.

WARNING: The following post contains many f-words. Like a drunken sailor, or like a drill sargent, I want to say the f-word every other frackin' word. f f f f f f f f f - those f'in frackers.

Why am I so incensed?
Why?
Because of language. The f'in language. I can't the the f'in' f-word, but lawmakers and big f'in' wigs government and business can say things even more profane than the f'in' f-word. They can say f'in' lies with no one holding them to account. I say the f'in f-word here, and I'm censored. Yet, the f'n f-words that are coming out of my mouth do little to no harm, but, the f'n lies they tell are harming people. Tell me that makes any f'in' sense. Rhetorical- no need to explain.

Here's a statement we must examine though.
“It really hasn’t been earthquakes, it’s been seismic activity,” he said.

King said he was skeptical of the link between the drilling and the shaking underground, but “the good news is nobody’s felt it, there hasn’t been any damage we have some time to kind of look at it.”

Texas State Representative, REPUBLICAN, Phil King

You are a moron sir. An earthquake is seismic activity. Let's make up new f'in' definitions for real things. Let's use what George Orwell called doublespeak. The Right Dishonourable lawmaker from the Lone Star State is demonstrating this manipulation in its pure form. He is using scientfic language, and distorting it so it sounds harmless. I can't go on anymore. Read the f'in' article for yourself. It's a f'in' crime I tell you.

no those are aftershocks of this one

thats the trouble with global incident map site, its only the last days data.
you missed it!

Not to say there couldn't be another one, like a mag 7+ there.
I thought that 5.7 I posted in the morning on the New Britain Island was a decent sized one in itself, I wasn't to know at the time that it was a foreshock of the 6.5.

ha! earthquakes eh, you never know they are coming until they happen.

THX for your kind reply.

When I lived there . . . there was a 6.X quake down island that killed many. IIRC it was in a mostly rural area but nearby towns saw the collapse of many buildings.

There's a railway on the Eastern side of the Island . . . and a stretch of the train track bed is constantly moving. They have to routinely redo the track there fairly frequently.

I had the honor of editing the professional English papers for one of Taiwan's top geologists. I think he's the best but he'd humbly argue with that because someone outranks him at the UNIV due to seniority, IIRC. LOL.

Multiple mag 5+ coming in to southern California

5.2 20km ESE of Anza, California 2013-03-11 16:56:05 33.498°N 116.462°W 0.1
5.2 20km ESE of Anza, California 2013-03-11 16:55:50 33.503°N 116.457°W 12.1
5.2 19km ESE of Anza, California 2013-03-11 16:55:42 33.506°N 116.476°W 0.1

usgs


In GEE, it looks like 8 millimeters/sec amplitude in the north-south, and east-west directions. Only 2mm/sec in the vertical.


ugh! The particulars keep changing. It looks like these were incredibly shallow.


Revisions to the 3 quakes above:

4.6 20km ESE of Anza, California 2013-03-11 16:56:05 33.498°N 116.462°W 0.1
4.7 20km ESE of Anza, California 2013-03-11 16:55:50 33.503°N 116.457°W 12.1
4.7 19km ESE of Anza, California 2013-03-11 16:55:42 33.506°N 116.476°W 0.1

I expect these will change several times more, lol. Still, looking at the seismos (for example, PB 084 Anza ) the shaking lasted at least 30 seconds. Lots of aftershocks, which is good. This looks to have occurred near the San Jacinto fault, not the SAF.
