yes it has been quiet for the last week, nothing above Mag 5 for NZ since the 20th March.
also seemed to come to a grinding halt with a 3 day lag with nothing above Mag 4 since April1 when there were 5 of them, until this yesterday

I think that New Ireland 6.2 on USGS could be a few split hairs too high, it has 6.1Mw on the CMT and BWMT
and there are no magnitude figures on the phase data at all ( at this time). Holidays short staffed ?

Geofon has 5.9 but thats still Automatic and doesn't say if it is mb or Mw

The Russians came up with 6.1mb so maybe the Mw figure is right

doesn't look like a 6.2 on SNZO though

Ah ha! I knew it would be one of you.

The second someone says "Ooh isn't it quiet - WHAM!"

It is only 4 days since the last. Not that long really and a few 5 and plenty 4+ in between so nothing particularly unusual I think.

* shrugs and walks of muttering - told them it would be quieter this year *

* well at least until the 8.5

There was a bit of a lull. The 6M and 5.5M came as the moon was full. I think tomorrow is perigee.

But yes, we were a bit impatient. I don't like the quiet. I guess it makes us nervous.

So. We Must RELAX!!!!

Hahaha!!! "Calm!"

Thank you EricBlair. I needed a good chuckle.

And not to totally derail the quiet, I noticed Oklahoma was still rattling earlier today, although a bit north of the most recent activity. Mag 3.3

Hmmm....it would have been a lot more relaxing without the grating, metallic voice!

I liked the field with the milkweed plants in the front. At least I think they were milkweed plants. Kind of far away to see for sure. If I would have seen some Monarch butterflies around them, I would have known for sure!

Didn't notice any earthquake clouds or fissures in the landscapes! (Gratuitous sentence to stay on subject!!!)

WOQ (& maybe now more calmly!)

GFZ have manually revised to 6.1Mw too

when compared to the Mentawai 5.5 SNZO says otherwise graph
especially given the distance difference of the two locations from SNZO
New Ireland Travel Time 7 miinutes 36.6 seconds, Distance 5518 km
Mentawai Travel Time 11 minutes 49 seconds, Distance 8951 km

maybe the depth is the difference in the trace match

a Mw conversion of the Mentawai quake would be helpful

I'm predicting the next 7+ to hit around the 9th-10th-11th of April, given that there's a full moon and a few planets aligning around then ;-)

Just hope if it happens, it's not in New Zealand, especially Canterbury!

BUT



That is Mb so it may grow up to be a big Mw one day.

British Columbia has been a little too quiet for a while now, the tension isn't being released, It could have an angry outburst pretty soon.

After checking this page at the Natural Resources Canada, for SW British Columbia, it does seem rather uneventful.
I did click on the "past year" page on the link above, and found the most recent earthquake over a 5 was on 4 Feb 2012, located 178 km WSW of Tofino, BC. That's a Mag 5.4 Mw, only 2 months ago. so it hasn't been too quiet for too long. (You know as soon as I post this, it will start earthquaking
)



Looking at a different area, I found something interesting (well, at least to me).

This Mag 3.7 from the Pinnacles, CA yesterday, seems innocuous enough, even though it's located smack dab on the San Andreas Fault zone. Taking a closer look under the Scientific & Technical tab, you'll find Directivity from Peak Motions.

This Mag 3.7 is an oddity--it was a strike-slip in the east-west direction. Most all the eq's in this area slip north-south. Weird.

Now on to the bonus...
I've been trying to understand how to interpret the First Motion Mechanism or "beach ball" plots for a while now, with moderate success. The "Directivity from Peak Motions" page above has a really easy to understand linked tutorial, titled Fault Plane Solutions .
Check it out, if you struggle with the "beach balls", as I do.

Does this mean that there may be more tension being added to the fault? It said something about a northernly direction but I'm not sure it means actually north or if it is an implied direction towards the direction the active plate is traveling. I'm new to studying earthquakes using this kind of input.

compare the "6.2" usgs has for New Ireland on the 6th April 2012
2012/04/06 16:15:56 -4.534 153.497 85.4 6.2
with this one
2011 11 28 122645.45 -5.48 153.73 25 6.1 MwWCMT PDE-W
can 60km really make that much difference in the size of the trace?

for those who automatically poo poo tsunamis from land based quakes, here is one I read about


Date/Time: 1983/10/4 18:52:15.84
Lat: -26.539 Long: -70.503
Region: Atacama, Chile
Magnitude:
Mw 7.7 [hrv] Mw 7.4 [usgs]
Mw 7.7 [p&s] Ms 7.3 [p&s]
Depth: 24.6 km
Deaths: n/a Injuries: n/a
Tsunami: Yes
Catalog Source: ehb
A 1.5-meter uplift near Chanaral was reported and some roads were blocked by landslides. A minor tsunami was recorded at Valparaiso. Felt strongly (VII) in northern Chile. Felt also in Argentina, Bolivia and Brazil. This appears to be a multiple event.

check the location, 18km inland from the Pacific Coast and 718 km from the reported Valparaiso tsunami.
1.5m uplift
, thats a bit of a heave.

6 seconds apart
first one was shallow at 2.6
next one deeper at 28.7

just wanted to report this

In my Humble opinion, I think there are some really cool things going on down there. I was talking to hubby the other day about how it would be to go down there and do some fishing, and check out how the lakes are doing. It won't be anytime soon. But it would be a really cool thing.


Just wanted to add, there's some great fishing down there. If anyone gets a chance. Big Bass.
