Great responses as usual - thanks guys....


So it's active but nothing usually much above 2.5...

Another article on the same subject.


Earlier estimates put the chance of such quakes at just once every 500 years. But new analyses by Oregon State University marine geologist Chris Goldfinger and his colleagues have revealed a more complex picture of the Cascadia Subduction zone, where the ocean floor steadily slips below the North American Plate – and where the region's earthquakes originate.

They found that Cascadia represents at least four separate segments, rather than one big subduction zone. Mega-quakes of magnitude-9 or greater occur less frequently in the northern segment and can rupture the entire fault, even as magnitude-8 earthquakes strike more often in the southern segment.

"It is not a question of if a major earthquake will strike, it is a matter of when," Goldfinger said, "And the 'when' is looking like it may not be that far in the future."


This article went into a little more detail in helping me understand the information being presented, as I don't know much of the science behind earthquakes as many. Regardless, I thought it was a good read.

What are we only posting unusual quakes now?


Every quake has a character of its own, if you look closely enough you will find something unique.

Check the depth of that one 4.2km on your source, 10kmUSGS/NEIR, EMSC had it at 2km

thats very shallow for an offshore earthquake.

There was a 5.0 aftershock 3 hours later too.

Anything happening on the rim of the largest dormant volcano caldera in the South Pacific is significant as far as I am concerned. 4.6ML is getting up there.

Screw the nit pickers.. I have learned a lot from everyone that posts in this thread, and can personally say that you are one of those that I have learned a lot from.

I wish everyone would just skim through the very few posts that are made here.. take what they will and leave the rest for everyone to do the same. This thread is much better than having 20 new threads a day.

Don't let them get to ya. If they don't like what you post.. then let them deal with it.. they have the problem, not you.



What do I know though.. I'm just a watcher..

I'm not nit picking, jeez, I just made a comment back to yours that there was "nothing unusual" when there was! the depth/size ratio. if that quake had of been on land the earths surface would have been torn asunder, like the Edgecume quake of 1987.

This forum would be way more interesting if posters made more comments about theirs and the other posts.

Muzzy, we're all in this together.. I for myself, was only trying to encourage someone that adds to this thread to continue to. I didn't even pay attention to what he was commenting on, I was only encouraging him to continue posting here.

I learn a lot from ALL of you, and value everyone's posts equally.

Now stop fighting peeps! You are all correct in your own ways. That quake should be mentioned because it was over a six, but MoorfNZ is correct that there is actually nothing unusual about it, and there is absolutely no harm in making that comment especially for the benefit of those who read this thread and lurk, and may nor be aware that this is common in this area and nothing to get excited about.

Personally I suspect that the depth was undefined, just a 'standard' depth, especially since USGS use 10km and EMSC use 2km and their standards when the depth cannot be determined, but you have also to remember that this event was in 5250m depth of water. The pressure of that depth alone is a massive containment.

Of course Muzzy, every quake has it's own characteristics, but as we sort of agreed it would be useful to add comments about why a quake was significant rather than simply posting a list of quakes (that is NOT a dig at you)

The addition of comments helps us all learn a little more and, since some have specialist knowledge of an area such as yourself on NZ. We are here to learn and not fight amongst each other so behave or I'll belt ye wi' me shillelagh!

Depth 20 km (12.4 miles) set by location program
Region VANUATU
Distances

* 215 km (134 miles) NNW (341°) from Santo (Luganville), Vanuatu
* 490 km (304 miles) NNW (337°) from PORT-VILA, Vanuatu
* 2077 km (1291 miles) NE (45°) from Brisbane, Australia

Location Uncertainty Error estimate not available
Parameters NST= 14, Nph= 14, Dmin=856.3 km, Rmss=0.9 sec, Gp= 61°,
M-type="moment" magnitude from initial P wave (tsuboi method) (Mi/Mwp), Version=1
Source

* West Coast and Alaska Tsunami Warning Center/NOAA/NWS

Event ID at00498048

GE map does not work and nothing on the Tsunami warning site for the Pacific yet.

Details are coming through now. As far as I can see nearest landfall is about 50Km. This occurred in 3,600 m of water so may nor produce a tsumani despite the depth. 77 miles from the volcano that is playing up.

Down to a 7.2 now. Any more offers? Who'll give me 6.9?

A strong earthquake has occurred, but a tsunami IS NOT expected along the California, Oregon, Washington, British Columbia, or Alaska coast. NO tsunami warning, watch or advisory is in effect for these areas.

Based on the earthquake magnitude, location and historic tsunami records, a damaging tsunami IS NOT expected along the California, Oregon, Washington, British Columbia, and Alaska coasts. At coastal locations which have experienced strong ground shaking, local tsunamis are possible due to underwater landslides.

Well that's good.

It is likely that a tsunami was generated. The maximum tsunami wave height near the coast of Pek will be 0.21m.

Caution: this information is based on risk models.

I prefer maps to lists and text myself too exinterp, but the way this ATS is set up its hard work putting jpgs on the actual page, you have to use the ATS Albums section under member tools, need about 3 windows open to be able to do it. Just putting on a link doesn't have the same effect IMO.

This is about the best I can do via google maps, I like to be able to have the text info popup tag about the quake come up when you click on a dot/orb/marker. I only found this map function a few weeks ago, still learning how it works.

You can zoom in and out and see clusters of quakes in various places.

Heres one of all the 3+ mag quakes in New Zealand May 1 - May 27th

Join the dots if you want , there are 279 of them


Let me know how/if it works for you, I could do this instead of the "boring" lists


Map


On the map you can see all the quakes I have previously listed here in May as text.
Of interest to me this month was the Whale Island Swarm, The Ngatoro Basin Swarm, the 4.56ML off of Northland, the 3 quakes along the Chatham Rise (out to the right of NZ on the satellite version) and the Takaputahi River, Bay of Plenty events which started out as a 4.56 with a few aftershocks and now seems to becoming a Swarm over a longer period (there are quite a few 2's there as well)
