Quake Watch 2012

reply to post by PuterMan


It's no secret that tracking boats is of interest to navies around the world

en.wikipedia.org...

Very quiet in NZ at the moment, last 5 days the number of quakes for the entire country have been
3, 4, 1, 4 and yesterday 4. It took 24 hours to find the 4 for the 7th June, there was nothing to put on the map at all for that day at the 6-12-24 hours afterwards mark (when I usually download the Geonet data.
No doubt more will appear later.
While it was quiet I did a final update on 2009 and 2010 counts and timeline graphs
Count and Energy graphs for NZ
Interesting that during the 2010 Darfield aftershocks they initially missed about five mag 5's on the first day, and also that the majority of the smaller a/s hit 3 days after the main shock - 373 in 24 hours on the 5th Sept UTC
The sequence of the Dusky Sound 7.8 was a bit different, with 354 on the first day, a lull on the 2nd day and then 320 on the 3rd day before dropping down to 180 then 191,155,120 ......
I'll have to redo the 72hr aftershock timeline rollout graphs for both of those quakes now too.

I say Final, but there were still 538 located events of undetermined magnitude for 2010, and 415 still to put a magnitude to for 2009.

Had to redo my Year Timelines format, the way I had it set out on the Y axis didn't actually show the true rollout timewise. Years Timeline Graphs
I still have to bring 2011 into line format wise with the others yet.

Not that anyone cares graphs are way down on the hit list

Rareish Aussie quake UTC: 08 June 2012 @ 11:31:05
N of Lake Keepit, near Tamworth, New South Wales
GeoAu 4.2ML Interesting graph from Armidale 112km away of it on that page, double tap?
Same on the IRIS ARMA BHZ graph
Geofon 4.7mb

I think a pretty good size quake just hit near Taiwan...

Waiting on details, but seeing it on the real time seismos.

Ahh, seeing as I managed a glimpse of it GEE, I will guesstimate 5.6 to 5.9


Yeps, 6.0 Taiwan

JMA have it at 5.9 Ml - don't have link sorry as it came into my database.

5.8mb translates to 6.1+ Mw and sounds on the high side as 5.9 Ml is 5.88 Mw

This will drop below 6 I think.

Geez man, I sure hope nothing happens at Toba because PSI has been down for at least three days straight. No real time data at all coming off that station- but it does appear to be archiving still at IRIS...

www.iris.edu...

Is today DAY 161?

EDIT: Answer: Yes, today = day 161 (had a minor problem looking that up on my excel spreadsheet, but fixed it...)

So that means PSI is outputting data, but IRIS is having problems delivering the real time channel streams.


Also, several smaller aftershocks have hit Taiwan, but you won't see those reported probably as they are likely below 4.5. You might see one that could have been big enough to make the USGS lists, but I doubt it.

It's nice to see someone else so fluent in seismogeekspeak.



So, who are you...

reply to post by TrueAmerican


Central Weather Bureau put an initial 6.5 ML, don't know if they review or update magnitudes.

a click on "More Information" display shakemap, lots of seismo station waveform traces for acceleration and velocity

there should be a ticker tape type font,, connected too the Japan Earthquake thread,,
running across the top,,like CNN,,lol
cause taking out NUCLEAR FUEL RODS,,ya wanna know,, whats shakin,,

at least a heads up too the guy,, driving the bucket,,,

reply to post by mlirenr


Those are excellent links, thanks!

Well PM, looks like John has invited a couple of his buddies. Fall back.

so being like a double helix form,,then,were are just an atomic process,,

helix are cool

mmmmm helix,,
with blemishes,, lol
i remember now,, the head shot theory,,
well proton bullet,,
goes in small comes out big?,,
the double helix picture,,
with quake intensity, spots,,blemish's

What, please, are your insights, conclusions, inferences . . . speculations from the wonderful graphs shown here:

seabreeze.wordpress.com...

???

I haven't the time to examine them real closely. There seems to be some significant variability--as in average activity variability--that is--averages of the activity seem to be quite different--from year to year.

reply to post by mlirenr


During my 14+ years in Taipei, we didn't get much concerned at 5.5 and below. We might check things on shelves at higher levels. The 6.X down island when I was there killed a lot of people . . . IIRC, from old substandard buildings collapsing.

As I understand it, Taipei basin is very vulnerable to liquifaction should a sufficiently intense quake strike there. May God have mercy on my loved ones there.

I have no idea, looks totally random to me.
Don't forget only 2009 and 2010 are comparable, as they are "final" data +/- 500 odd un-estimated magnitude events

What visitors are supposed to do is look at the graph, say 2010, figure out what day they want to look at, (the Days are numbered 1-365) then use the search function (top right hand column) to see what was happening.
for example lets have a look at day 139 which had 130 quakes in 24hrs but no colouring to the column, so not a 5+?, so day 139 is May 19, search 19.05.2010 .........
ah ha, a big swarm offshore around Whale Island in the Bay of Plenty preliminary data has 58 events for that day so that was just the tip of the iceberg , heres the preliminary map for that
Remember Tina from Whakatane posted a few comments on Quake Watch 2010 at the time of having felt the quakes?
I haven't had time to do the revisions/updates for each day, its a huge task plotting 21,000+ co-ordinates

try another, Day122, May 2nd 113 events search 02.05.2012

ah ha another swarm, Lake Rotoiti, only 8 events shown in the preliminary map, odds there were a pile more?.
What people do with what I present is up to them, but the options are endless, I could spend all day every day going through the graphs and picking out stuff to research, but its too much for the head sometimes.

I just added a link to a calender with the days on it so people can easily work that part out.
I've set it at UTC time so it matches the data.

heres the link for ya if you aren't following the story anyway

Day Number Calender set to GMT/UTC
