Quake Watch 2011

reply to post by PuterMan


Yeah, I just lifted those through the Search page, 6:44 AM NZDT, someone must have been up to midnight trying to fix the programme.
Still a day behind (as you say)

just had a quick look over the drums
looks like a decent mag 3 about 20 minutes ago on the East Cape, www.geonet.org.nz... or Hawkes Bay area www.geonet.org.nz...
maybe it was another South of Gisborne quake ( part of that Swarm a few days ago),

Stiil regular aftershocks in Christchurch www.geonet.org.nz...
and not much down Fiordland way www.geonet.org.nz...

all the rest are flatlining

RSOE is down due to a DDOS attack

shhhhh

the quakes are sleeping. everything relatively quiet.
shhhhh

ignore me

yeah they have been down for the past two days lol.

something just happened in our area 30 minutes ago, its on LISS, none of the Networks have ID'd it yet.
Could be Fiji or Tonga again, or maybe towards Antarctica
aslwww.cr.usgs.gov...
its at 14:55 UTC or so

Scott Base shows it aslwww.cr.usgs.gov...
as does South Pole aslwww.cr.usgs.gov...
and Marble Bar, Au aslwww.cr.usgs.gov...
and Solomon Islands aslwww.cr.usgs.gov...
and Charters Towers aslwww.cr.usgs.gov...

stronger down south though

looks like a Mag 5

two and a half hours since and still no reports in

Another Southern Ocean one lost to the void.

I wonder how many have never been reported over the years?, must be hundreds of them, although anything over Mag 6 would be hard to miss at least since the 1970s.

I've seen half a dozen go lke this in the last few years, I have a file somewhere of a few of them.

Maybe it was not a quake and accounted for = mine blast, missile detination, etc. or the ice - oh the Dreaded ice, or it could have been a snow plow

Here's One from Lake Yellowstone which also showed up on a few other instruments - and no quake reported. The Lake is frozen so we'll just call it the ice.

Just seen this on BGS

Woken by a 4.5 aftershock here this morning c. 7.30am - was close by us nr Oxford.

And now a bigger aftershock to end the day with - a 4.6 which was widely felt. I was outside talking to a friend when it hit and heard and felt it.

I have responded in your thread.

Try the exercise I linked to. It will enhance your understanding.

reply to post by Anmarie96

I doubt it, too big of a signal, something that big would have to be a small nuclear blast. Most land based nuclear tests were 5's and some of the Tahiti Tests the French did were in the Mag 6 range.
I think it was a genuine earthquake, possibly down south around the Antarctic Plate edge.
Compare the screenshot I took yesterday with the West of Macquarie Island quake today 08:06 UTC on the same LISS station graph aslwww.cr.usgs.gov...

about the same sze 5.0mb

Just realised you were talking about yesterday.



Nothing on CTAO: CTAO.IU.00.BHZ.2011.034

reply to post by muzzy


CTAO as plot

Nothing showing on this either of Marble Bar. That quake has been wiped. What is more all of a sudden there are NO records before today for QSPA on ANY channel. That has to be unusual as this recorder is on LISS. The locations are 00 and 10 on LISS for channel LHZ but there are many other channels and locations going up to location 60.

Bud explorer page for QSPA

Nothing on SBA (Scott Base) SBA.IU.00.BHZ.2011.034


Now I cannot state that there are normally days before the current day but it seems very strange to me. I shall be watching this.

stronger down south though

looks like a Mag 5

Yeah that image I posted was of Day 34 SNZO (03.02.2011UTC) but I didn't put the other stations up as I didn't take screenshots.
Its kind of weird that nothing shows on those graphs you posted, I definitely seen a wiggle on LISS on the stations in the quote above.
I wonder if there is any archive of the LISS images?? probably too many for them to store

I just saved a bunch of mid-day images of LISS that show that Burma India and Vanuatu quakes, if you just look at SNZO it looks like one long event, but looking at some other stations around the South Pacific you can see that it merged with the Vanuatu 5.7 and the aftershocks of that.
I thought LISS was simple because the lines are quite well defined, but you have to take each station into context as per distance from the events.

I'll post them later, its quite nteresting (well I think so)

A big one for the continuing "swarm" around Cloverdale

yep, still nothing... notice the depth - 17 km, the 3.1 was at a zero depth
