Quake Watch 2012

reply to post by muzzy


Congrats on teaming up with Earthquake Report... Love that site!

I'm saddened to hear there was a little boy that passed in the recent quake in Indonesia. Sad!

Yeah they do a pretty good job, hopefully I can add some more info to the mix, Armand the main guy there said the page with my map and graph for Ahar, Iran aftershocks got thousands of hits from Iran (he tracks visitors locations), which is good.
They are bit lacking on the Sulawesi event though, wujotvowujotvowujotvo has done a great job researching that one (on the last page) well done wujo
so don't give up on Quake Watch ATS just yet, the quality is good here too.

I have been following Japan for a month now, downloading the JMA revised data every few days. So have got enough data to do something with it apart from maps, heres the numbers per day and energy released as a series of graphs
The period is July 13th to Aug 13th, and finishes a day before the 14th and the Sea of Okhotsk 7.3ML which will blow right off the graph at 41,131.00TTNT energy released. (data not available for the 14th full day for another 3 hours)
I thought there might be some kind of trend to see, the numbers count doesn't seem to show anything, but the ER shows a slight drop off at least for the 3 days prior from 473, 376, to 155 TTNT.

Need to get more data

Oh BTW, the data is from 1.0ML magnitude up

Now that's got to have made a few million people very NERVOUS!

Been a longtime I believe since anything of this size and so shallow has hit this area.

Let's hope it's not a prelude to the one...

Being quite an avid reader of the Arkansas thread a while back, i know this 3.3 likely caused some shaking/swaying.

Indeed, let's hope not. This 5.6 sure catches the eye.

reply to post by murkraz

True, it does catch the eye, but hopefully it doesn't portend anything major is in the offing.

I recall a few others in the region so I did a search of the NEIC database here and got the following results**:


So, there have been a few mag 5.5-plus events within 160 km (circa 100 miles) of today's, but the last one was back in 2008. (On Christmas day, no less!) So, they're rather uncommon, but as we've seen bigger ones in the past few decades we can knock on wood and hope for the best. Note that in Sept 2001, there were three in just three days, but even they didn't lead to anything major.

** Just a note: while the NEIC database should be complete for larger events in recent decades, it ain't always so. There might have been one or two others in that region as well.

EDIT to add: though all but one of the quakes in that list have a listed depth of precisely 10km, that by no means implies that they all really occurred at that depth. It's just a "default depth" and we shouldn't read any more into it than that.

Calling Westcoast, you still out there? Haven't seen you around in awhile. You ok?

Think we will see something around S. Cali. to keep up the ping pong effect?

Very strong (deep) earthquake below Papua New Guinea
PNG continuous to be shaken almost every week. This time a M6.2 earthquake struck at a relatively deep hypocenter of 80 km below mainland PNG. Mt. Hagen is located at a distance of 115 km from the epicenter.
The shaking will be felt in a very wide area of hundreds of km. We do not expect this earthquake to be damaging nor to inflict injuries because of the epicenter’s location and the depth of the hypocenter.

Anyone know of an earthquake in Mexico? My mother just came in and was searching through all the channels to see if she could find it on the news. I searched online and have found nothing.

She says she heard it on the radio while she was out running errands earlier and she said it's not being reported anywhere. Apparently the radio dj's were asking listeners to call in and report what they knew. This was obviously a Spanish speaking station. Anyway, she said the news on the radio was that it was a 6.8 and some were saying higher in the 7.8 region and it was centered somewhere around Mexico City and sadly there were casualties.

Any info?

Wow! Uh.....I see no answer from anyone so I will give it a shot.

Is it possible they were talking about a historical day?

Try to U2U trueamerican, he keeps his eyes on the seismos. If something that big happened, he saw it.

reply to post by conspiracy88


i am not seeing any eq in that area today anyways like the above post they could of been talking about a historical eq that happened in that area.

Hi!! Yup, I am still around, just not posting much lately.

These ones got my attention.....I say 'these' because there was more than one!!!

According to John Vidale, Director of the PNSN, he doesn't believe these are coming form the subduction zone, but on the spreading ridge or a nearby transform fault. (per his post on fb)

This is made obvious by both the location and depth of the quakes. Doesn't mean there is no cause for concern (any quake of signifigance in this region warrants attention), but just not likely to be directly from the CSZ.

As to the 'yin/yang'....not sure. As JustMike pointed out, we don't see them all too often right about there....I'm thinking that perhaps off-shore Vancouver Island. If it were coming from the CSZ, I would say off-shore Southern Oregon or Northern California.

Hope you all are having a good summer!!

Oh, westcoast, are you new here? I don't remember seeing you before.

Strange isn't it how people react to quakes. I saw the 5.5 off Washington, looked at it and decided to ignore it as not particularly significant but interesting.

But it is. They all are!

The only question is when?

reply to post by conspiracy88

I agree with others who have said that this talk on the radio could have been in reference to a historical event. As Mexico City's most devastating earthquake in modern times was on Sept 19, 1985, I am wondering if what your mother heard was related to that, as maybe the beginning of a one-month campaign prior to the major evacuation drills that are to be held on Sept 19:

Every 19 September, in all public buildings at Mexico City and all the nation the civil protection authorities conduct evacuation drills to evaluate the evacuation response in the case of an earthquake.

(From the Wiki in their article about the 1985 Mexico City Earthquake [under the "Legacy" section near the end].)

It's reasonable to tie in their drill date to the previous large event, just as they do in other places. It also seems reasonable that they'd run a public info campaign prior to this to make sure that the vast majority of people will know what's going to happen on Sept 19. After all, there are plenty of young people in the region who were not even born when the last big one hit 27 years ago.

Best regards,

Mike
