Aren't those islands volcanic? Do you think they are volcano related?
I have a vague recollection that there were grumbles around there not so long ago. (Forgive me, my memory is getting really bad).

Most definitely volcanic

You can see those quake on this graph from Bud Explorer
www.iris.edu...

The Red one is the Kermadec quake 5.7-6.1

The Bay of Plenty is a Spreading Zone all the way up to the Havre Trough, so I think all these (incl the Kerm quake) are related to the same thing - spreading of the crust.

couple of micros at Mt Ruapehu volcano as well today

and one at Waimangu, Lake Rotomahana (near Tarawera Volcano)
a very volcanic day

I thought it would go further north than Havre Trough and Pacific plate subduction would play a large part in it too. But I haven't looked closely at it. The Samoa/Tonga/Vanuatu movements must surely affect it too?

maybe it does,but this is where the subduction theory falls down, if that area between the Kermadec Ridge and the Colville Ridge ( the next string of ridges to the west) is spreading then that means the Australian Plate is expanding eastwards OVER the Pacific Plate, rather than the PP going UNDER the AP

maybe a bit of both

Hmm, interesting theory. I hadn't thought of that.
Now you're getting my brain ticking....

Subduction falls down all over the place!

Yeh yeh, bah to subduction!
So it's a 6.2 now? Couldn't read the pdf with the long strip down the middle btw.

@ muzzy, hope there are none bigger heading your way!

Can you explain? I have these as long one page ones so as not to cut across image but if that does not work i need to know. What are you using? Adobe?


So it's a 6.2 now?


I must have been I guess but the main page says 6.1

The trouble is they never change the subsidiary pages after the event. They are generated once and that it it. Pretty poor really.


yes bah to subduction


Indeed but subduction always falls down - pun (OK very bad one)

PuterMan... I saw in a post the other day, Robin mentioned something about your thoughts/opinions on subduction zones. I'm really curious to know what they are.

If you wouldn't mind sharing, or pointing to a previous post of yours that has those thoughts, I would greatly appreciate it!

I think I felt a small tremor at about 0230 am. Don't live near a highway, so no big trucks, and this is a small town so I would have heard anything big enough to shake my house. I live in Central Illinois, Clark County.

I've been keeping a very close eye on the Juan de Fuca fault and the Mendocino Triple Junction (off Eureka California). Small quakes have been working their way up the San Andreas over the last month, seems higher than normal and increasing in a northerly trend but I haven't compared long-term numbers. But, here's what I've noticed, there have been NO quakes above a 1.9 in the last month or so north of Eureka.... until today (last 24 hours)!

Last week we got several quakes at the north end of the Juan de Fuca fault complex, in Canada, and now today this (pictured below), a 3.1 and a 4.6 out in the Ocean, right on the Juan de Fuca! Reasonably small but certainly in a trend saying we may have a big one there soon!



I've been following this because of a prediction saying a 7.9 would occur right at the Mendocino Triple Junction. It's predicted for May 26th, 2011 - details in 7.9 Earthquake in California predicted by proven and validated SOURCE * lead-in to volcanic activity. It's based on channeling so please make any comments on that thread concerning non-earthquake stuff.


anyone else following this area or have thoughts on the quakes on the Juan de Fuca?

Just picked this one up on downloading latest quakes off Geonet, can't believe no one reported feeling it given the shallow depth and the location 10km east of Wairakei, and 15km north east of Taupo township, Waikato .
Just after noon NZST.
Mag, Ref, Lat, Long, Date/Time UTC, Depth
4.741ML, 3517544, -38.61735, 176.22408, 2011/5/23 00:59:27, 2.4km

there was a Mag 4 under Lake Rotorua ( old crater lake ) 34 minutes prior, which at 159km depth you can understand no one feeling it.
Mag, Ref, Lat, Long, Date/Time UTC, Depth
3.968ML, 3517530, -38.0583, 176.30185, 2011/5/23 00:25:34, 159km

Lot of quakes in volcanic areas the last couple of days
