Quake Watch 2013

Another one along the Southern Mid-Atlantic Ridge:

5.2 Southern Mid-Atlantic Ridge 2012-12-27 11:33:59 12.362°S 14.874°W 9.5
earthquake.usgs.gov...

This was the one prior:
5.3 Ascension Island region 2012-12-26 15:24:26 10.432°S 13.170°W 9.2

Do larger ones like this this close together in terms of distance tend to be the norm out there? I'm not sure if I should call it typical, or oddly spaced/timed.

Muzzy, terrific kick-off for the new thread! Kudos

Puterman, thank you for you fine stewardship of Quake Watch over the past 2 years.

I look forward to a 2013 filled with continued learning with my fellow quake watchers.

Hope you all enjoy a peaceful new year.

A 5.9 Central California?????

Also look at the entire map , it's lit up like a Christmas tree , no pun intended, ok , maybe a little intended

looks like there will be a cross over period for the last week of 2012 running into 2013
and why not, I'm 7 hours into the 28th Dec anyway
feel free, it's YOUR topic to use

did an ANSS search but had the lat/long wrong forgot the - for S and W
give me a minute ..........



here you go (click text for the results)
catalog=ANSS
1990/01/01 to 2012/12/28
mag 3-10
0 km to 500 km from (-12.362,-14.874)

I presume this be the static map of that

Excellent.

I'm very glad you open this thread, we will have good time here with a lot useful information.

Thank you


Some info about latest earthquakes in Chile.

That's not earthquake, forget that single automatic report.

Interesting, no where is it found on USGS, you'd think that would be newsworthy!

Thank you , that's not the first time i've seen that , it's a bit unnerving to see that....what possible reason would there be for it to show up at all with no actual quake?

Local noise from wind or anthropogenic activities.

Incessant signals generated at the ocean floor and coasts induced by ocean waves.Microseism

Cryospheric events associated with large icebergs and glaciers.

Above-ocean meteor strikes - explosion also all other kind of explosions.

Industrial accidents and terrorist bombs and events.

Also some other influences but I think you got a point, seismometers sensors are very sensitive devices.

You are incorrect actually, it is an earthquake. It is just not a 5.9 it is a mag 3.3.

Have a look at this post in Quake Watch 2012

Just for posterity as the link in my other post will eventually go. Here is the seismogram of the quake.



That is not a phantom. The pick is wrong that is all.


For your enjoyment and delectation, and to see a bit more of the background, I have beefed that seismo up a little...

See just above mountaingirl. It is on USGS you just have to look, and never believe what any site says until you have cross checked it with one or two more!

It is not uncommon for this to happen and I guess this has probably come from EarthScope when these 'anomalies' are frequent.

Nice catch, I was watching higher magnitude on many different station that's way I did not find him.

I do not know how to bring a quote from one thread to another, so your index finger will have to work a little today.

I thought this post from Olivine, and this other info I dug up might be thread worthy.

Just a heads up!!

Hopefully this link works.This post is related to the last two posts on the last page of that thread.

Cascadia could go at any time, and there likely won't be any warning.
Just make sure you have emergency supplies at hand and plenty of drinking water stored away if you live in the PNW (and anywhere else for that matter)
We just replaced a lot of food items in our emergency boxes last month, I am getting a bit sick of eating beaked beans out of the can lately, but I bet they would have be most welcome if a mag 8+ had hit us and the stores were closed or unable to get supplies.
I just replaced our water supply this morning with fresh water, I do that every month.
And keep enough LPG for the BBQ to last a month.
All tradeable for cigarettes of course in a WCS (worst case scenerio)

17 seconds into 2013 ................
Perhaps the first quake of 2013

NZ Daylight Time Tuesday, January 1 2013 at 12:00:17 am
Latitude, Longitude -41.82, 174.39
Intensity ? unnoticeable
Focal Depth 58 km
Magnitude 3.0
Location 30 km south-east of Seddon
112.6 km south-south-west of muzzy's house (my edit)

Of course it is still 2012 in the rest of the World yet

We don't normally bother to stay up till midnight, but some clowns in the neighbourhood started to let off firecrackers at 00:00:00 NZDT and woke us up, still going 58 minutes later

Have a safe and prosperous New Year everyone




edit: now I'm wide awake, might as well look into it in more detail

Latitude, Longitude -41.8193, 58.3203
Magnitude: 2.9608 ML
# phases used: 49
Source: CQL

[color=C48189]h ttp://wfs-beta.geonet.org.nz/geoserver/geonet/ows?service=WFS&version=1.0.0&request=GetFeature&typeName=geonet:quake&outputFormat=csv&cql_filter=origi ntime>='2012-12-30'+AND+origintime0
This is the (CQL) Contextual Query Language query I used to get the Excel csv file with the data for 30/12/2012 to 02/01/2012
(you just copy and paste it into your browser address bar, just bring that h and t together at the start without the gap to make it an html address that works.)
warning: it will open an Excel csv file in your " downloads" rather than open a web page
Change the dates to suit whatever time period and magnitude data you want.

Yesterday I did a CQL for 01/11/2011 to 31/11/2011 Mag 3+, and got 601 results, all " reviewed" so the NZ Earthquakes Catalog has been updated
I had 399 events of mag 3+ from a search using the old Magma page on 21/10/2012, so its a quite recent update

however ................
I just did another Magma page search for 01/11/2011 to 31/11/2011 Mag 3+ and got 610 results, so there must still be 9 left un-resolved?
