I missed that one, hadn't checked the site last evening.
Am going to have to get one of those alert programmes for my cell phone

3:32 am here, just woke up, thought I heard the Tsunami Sirens,must have been dreaming

The intensity of the quakes here in NZ seem to be increasing the last few months nation wide, thats getting to be about a Mag 5 every 5-7 days, unprecedented as they are scattered, not part of an aftershock sequence

I wonder if this one is related to the Swarm over at Tologa/ Tauwhareparae to the east over the last couple of days, 177km to the east, about the same distance away as the depth of this quake


Seems to fit in with the seismic cross section at that latitude




Showed as a Mag 6.3 at SNAA station in Antarctica , according to NEIC

I would say the answer is no not imminently. None of the blogs are reporting anything (I mean serious blogs like Eruptions!), it is not being reported on the Smithsonian either.

Keep an eye on the VAAC sites (See this page) Click on Toulouse for ETNA

Most recent ten messages, regardless of volcano:
23-04-2011 - 06:00 UTC - 2011-27 -- ETNA -- has graphic attached (Graphic only)
12-04-2011 - 06:34 UTC - 2011-26 -- ETNA

You can also get to the VAACs from the Met Office

Nothing going on at present, but...........

I would say however that the 4.0 that just went off makes this something to keep an eye on. It does seem to be getting bumpy over there. They seem to be getting bigger. I will see if I can pull a seismogram in the area and have a listen.

thanks for the info, found another thread on here from someone who lives near etna and they are saying that they can't see the volcano due to weather, they don't seem to be too concerned though, I just thought it seemed worth a look as the earthquakes were getting bigger.

I have a sound file ready with the 4.0 and several very small quakes that follow after it but I can't upload to 4shared at present - technical problem and I am not allowed to put it on drop box as it loads the sound file directly - actually, hold on , I will zip it and then it won't load.

There we go: dl.dropbox.com...

It is very eerie listening to the sounds coming from the earth,
is the amount of quakes recorded yesterday and today a usual occurrence?
p.s sorry for the questions and thanks for answering a complete novice and showing me further links

As of May 6th 2011 NZST
In New Zealand and around the coast there have been;
7 quakes less than 1.0
810 quakes from 1.01 to 1.999ML
4217 quakes from 2.0 to 2.999ML
1485 quakes from 3.001 to 3.999ML
196 quakes 4.002 to 4.997ML
16 quakes from 5.006 to 5.91ML
3 quakes 6.343, 6.351 on land and 6.516 (Kermadec Ridge)
and 142 quakes of undetermined magnitude

map and kmz link for the Mag5 +
original source

I just did a download this morning, 6875 lines

On my NZMag5+ Blog I had to do some revisions , one ChCh quake was downgraded below 5.0, one as brought up from 4.7, one I missed in March in the Bay of Plenty, couple of other ChCh ones were relocated and revised upwards a few decimal points, one of them was originally at Pigeon Bay on Banks Peninsula (moved to south of Cracroft) and the big Lyttelton 6.3 has been relocated 1km to the NW of the original Lyttelton location to the Port Hills above Ferrymead on the Christchurch side

OMG I'm going to have to go back over 3 months of csv file and txt files and change the wording from "Lyttelton Aftershock" to "Port Hills Aftershock"

The new location is LAT/LONG: -43.5829, 172.6797. Looking on Google Earth and Google Maps its in a small valley coming out of the industrial area between Hillsborough and Ferrymead, not sure what the valley is called, the road through the middle of it is called Avoca Valley Rd, and there is a Cemetary there called Avoca Valley Cemetary, so my guess is that its called Avoca Valley

"the Avoca Valley 6.3 earthquake of 2011/2/22" has a nice ring to it.
Makes you wonder who thinks up the name for quakes, like the "Darfield Quake of Sept 2010" is actually closer to Kirwee than Darfield



Fiordland has been very quiet this year.

The magnitude 4.2 in Jamaica yesterday originated from a mountain range known as the Blue Mountains which are presumed to be an 'extinct' volcano.

Here is an article on it.

The number of quakes is not usual if you look at a year of quakes. On the graph below the green line is the line of the number of quakes daily - cumulative - prior to around Feb/Mar 2010. I have drawn an orange line which represents that period onwards to Apr 2011. It shows an increased daily rate but fairly steady at the new rate (the line is almost straight). Then in April 2011 the rate has ramped up quite a bit.

Etna is having what is called a swarm. It sounds scary but it is not really and it happens in places from time to time. Yellowstone for example can have a swarm of a couple of thousand earthquakes and still stay 'corked' !!



When you look at the magnitudes over the same period you can see that there is very little variation. This is good news since it probably indicates there is nothing to be too concerned about BUT this is a volcano. EMSC only publish down to mag 2.0. The number of minor quakes could be significant (another) BUT for an eruption we would be looking for Harmonic Tremor. This is not earthquakes - it is like a long continuous shudder as magma is pushed through the tubes on it's way to the chamber or the surface.

The good news is that the seismo I listened to has absolutely no HT apparent either audibly or in a spectrum analysis, in other words it is not close to erupting right now.

reply to post by JackieO


By the way - take a look at this page where I have assembled a few earthquake sounds. There is also a link to my 4shared site where there are more.

In particular however go to the Mt Erebus site as there you will find examples of harmonic tremor. They speed it up a ;little too fast for my liking (100 x where I normally use 20 x)

reply to post by PuterMan


these sounds are fascinating, I thought the harmonic tremor sounded a bit like the audio you hear from whales in the ocean.

Thanks for all your help, my other half thinks I have lost the plot lately as I have been spending all my time on here reading up and following various links you have given so that I can be better informed.
I think I have been reading too many of the doomsday threads on here which is making me paranoid

on the subject of earthquake noises--Are you guys familiar with Jack Coles and his work using radio bands to give windows for possible earthquakes. I haven't been on syzygyjob for some time, I just popped there today and he has received multiple enormous main signals this type of signal is bran new for him.

That is Togians - right near Una-Una volcano!
Sorry, about 160 Km East from Una-Unau; area has regular big quakes.
Interesting is that it is the deepest trench in Indonesia at more than 4,200 meters.

Well I could not find that exact statement but I had a good look around the site and at the "Geoseismic Lab Reports Near Real Time Data" which purports to be uploaded once and hour but fails to mention which seismo it is taken from, unless I missed it. As to the interpretation of the signals? Well I am away to have a coffee and I will probably have forgotten all about this by the time I get back to the computer.

In other words - NOT impressed.

It's not a big quake; however, I can not recall ever seeing one in New York.

Quake Jolts Southeastern Iran
14:39 | 2011-05-07


english.farsnews.com/newstext.php?nn=9002171090

TEHRAN (FNA)- An earthquake measuring 3.1 on the Richter scale jolted the town of Jiroft in Kerman province, southeastern Iran, on Saturday morning.

The Seismological center of Kerman province affiliated to the Geophysics Institute of Tehran University registered the quake at 08:26 hours local time (0356 GMT).

The epicenter of the quake was located in an area 57.37 degrees in longitude and 28.49 degrees in latitude.
