Quake Watch 2012

reply to post by Nyiah

They have a similar setup to Japan, with a feeder sub-division, called ISIDe, you can access the database here, just need to type in the numbers at the bottom so they know its a human at the other end and not an autobot .
I had saved this site for a while, couldn't figure out what to do with it, until today I ran the address through Google Translate and figured it out. Looks like it gos back to 1989.

Hey,muzzy was it similar to this?

Was what similar?.
Not sure what you mean but thats a cool seismic zone map of the area, now I see why P'man has North, Central and Southern on his QVS locations tool for Italy, I though that was a bit vague, but it seems to be legit (well since 1994 according to that article) Thanks
There has been a bit of a swarm in Oct up near Torino (NW near France) that is away from where you expect most Italian quakes to be.
Vesuvius is quiet, they must collect data independently for that spot.

Pure coincidence I can assure you.

You cannot get a precursor of the earthquake on a buoy unless there is an earthquake to produce a tsunami to alter the water pressure.

Just because there was a glitch on a buoy near where this earthquake happened does NOT mean it had anything to do with the earthquake otherwise there would be Mag 7 earthquakes all round Australia where these glitches on buoys are occurring all the time.

On the other hand if like me you have a login you don't have to bother with those boxes!

It is on my list to add to the normal listing to QVSData.

I have just emailed you the CSV files for all the quakes from 1983 to the end of October 2011 which was the last one I collected and have not got back to since.

i got a friend in Kaanapal should i be advising her to head inland she says shes on the 7th floor but i have no way of figuring out if she needs too or not and whats the estimated wave hight supposed to be as she said the waves are suposed to hit at 1030 but didnt say how high they would be

This was posted by several folks earlier. So far I've heard about 3-5 feet. Your friend should be okay. But for her sake stay tuned.

I guess she has about 45 minutes left to stand on a chair in case!

Max 5 ft on the west side of Big Island and down as low as 2 ft in other areas. Somehow I don't think in a 7 storey building she is in any danger but read my disclaimer.

Interesting that Canada have this as 7.1 Mw which is the value first put out the the tsunami warning centre.

Official says water level at Makapuʻu went up a foot and then dropped 3 feet; bigger waves expected

Seems to me that there are a huge number of aftershocks in the medium power range of 4 to low 5. They do not seem to be going down in strength. This is worrying.

Feels that way, but using USGS values and stuffing it into Excel the trend line says otherwise.



ETA: The USGS phase data seems wrong. They have 6.5mb and 7.2 ML which translate to around a 6.8 Mw. Bearing in mind that the TWC put out 7.1 Mw first and Canada have 7.1 Mw as well, are we going to see a change - later?

Thanks as always Puterman. Based on our last conversation here I will remain worried. If this is the Pacific plate springing back then these quakes are just in the right place for the beginning of the process.

Yea, don't mind me, I'll worry until the aftershocks calm right down.

The locations are different too. GFZP and NRCAN have the quake centered farther south and west, over the open ocean, while USGS has it located inland.

Here is a link to the IRIS back projections page for the Mag 7.7 in British Columbia.

It shows four different models of the rupture, from seismos in North America, Europe, Australia, and global.
(The animation requires Quicktime)


Wanted to add that the San Fernando area of Los Angeles had a Mag 3.9 half an hour ago, already reported felt by over 1300 people. If you zoom in on this USGS map, it doesn't look like it occurred on a known fault.

I get this funny feeling that the quake in Canada is just a symptom of something bigger to come. I'm not sure if it is going to be north or south of this event. It's good that feelings aren't good predictors of things. Seems like we have had quakes a lot more in areas that don't usually have quakes.

That would be great.
I already got 2012, 13,000+ events, thats enough for 20 maps for now, All and 3+, one of each per month.
Will take some space up on Dropbox though, Oct All was 1mb alone.
I'm trying to get each country on the blog menu up to scratch for 2012, at least with 3+ maps.
Japan is the hardest, because NIED only gives out one day at a time.

This is a VERY active area of earthquake activity, so although a 7.7 is quite big, its not the biggest that has happened on or near Haida Gwaii.
1949 mag 8.1

The shaking was so severe on the Haida Gwaii that cows were knocked off their feet, and a geologist with the Geological Survey of Canada working on the north end of Graham Island could not stand up.

some more historic events here

I thought this page would be the one to watch the aftershocks, but they are a bit behind USGS, Canadians are a cautious bunch, not prone to over reacting www.earthquakescanada.nrcan.gc.ca...

No reports of how the Tsunami affected Pacofi (1.7m) or Lockeport (1.5m)
GDACS Locations affected by Tsunami wave (155 locations).
Nice pdf on the tsunami and background on the islands here
Its not the end of the World yet, when we get 4-5 of these on the same day in different parts of the Globe then its time to be concerned, but hey what can you do anyway except be prepared to go to higher ground (if there is any)

edit on 10/28/2012 by Olivine because: add info

that area is prone to small quakes, the SFV area is where the 7mag quake happened in 94' Northridge was the epicenter. I remember it well.

looking at the USGS map it seems like the Ring of Fire is catching up for the rest of the slow year.

Edit : some earthquake historians will say it wasnt a mag 7 and looking at the history books you would be correct however I knew people at CSUN who registered the initial magnitude and 7.1 or 7.2 I have even seen shirts with the " I survived the 7.1 mag northridge quake" and even the martin Luther king quake.

It is said those in power lowered the magnitude for insurance payout reasons. ? who really knows.

Said in best BBC voice..."And in other news.....seismologists are arrested for not predicting this earthquake....."

Yeah, just from past experience I'd say the Canadian site is more "rigged" than behind, muzzy. This is the sheet for my area.
www.earthquakescanada.nrcan.gc.ca...
Once the map pops up you'll see a town called Pembroke on the left. Just west of Pembroke 20 miles is a town called Deep River. Next to that is a 55 year old nuke plant [Chalk River]. Guess what? Neither is shown on this map or the next map section west. They are both invisible. An oversight? We have invisible quakes too. Quakes that show up on USGS but not on the CDN site. I'm pretty sure there was a 3.1 right below the nuke plant a couple of years ago, but with the town of Deep River being "invisible" it's hard to get your bearings and be sure?

Great work gang! I pop over here a lot to gain some understanding into how things are unfolding. Just thought I'd pass on my thoughts about the crappy CDN site.
