Interesting how it was felt so strongly in Opotiki, Napier, Palmerston North and Wellington

that one shook the whole edge of the Australian Plate



www.geonet.org.nz...

Geonet have it as a 6.4ML, and further east near the Trench. They may have it wrong though, they aren't usually very accurate with anything beyond Rumble 4. EMSC, GEOFON, USGS and RAS all put it under the K Ridge at approx 90km depth.

Hi all, I am newbie on this site and find the threads on natural disasters etc fascinating. I have spent the last month since the Japan earthquake reading quite a few and am able to understand some of what is being said by people who are far more intelligent than I am and on this thread there seems to be quite a lot you, so I am hoping that someone can help with a query I have regarding the live internet seismic server. I have just looked at this page
aslwww.cr.usgs.gov...
and am curious as to why they all look similar. Please be gentle in your replies as this is the first post I have made on here!

They are all currently showing the magnitude 6.6 south of the Kermadec Islands this morning
earthquake.usgs.gov...

Most magnitude 6+ show on siesmographs all over the World

Look and see which ones are the thickest, strongest to get an idea where the quake originated.
ie look at SNZO (closest), RAO, PMG, CTAO and MBWA see how they have a bigger trace than the others?, thats because those stations are closer to the epicenter.
this map shows where each station is

Thanks!

Read the link you posted...

Seems like the locals felt that this was much, much higher than a 3.4.......

Plus note the differences that they felt and noticed that were not like any other quake they've experienced......and they're native Californians!

Wondering why they say this one was way more different...

Your take?

Welcome to ATS and in particular to the QuakeWatch thread.

The LISS recorders (The page you linked) as muzzy says show pretty much any earthquake over a magnitude 6 to a greater or lesser degree. A magnitude 7+ will turn many or all of them black.

If you really want to learn how to read them, and understand how they work, read this page which I created especially so that people could understand the LISS helicorders. It gathers one or two web resources in the smae place which makes it easier to follow.

Earlier I was reading about new reports on more dead fish and birds in mass numbers, just like right before last month's megaquake....around the California shorelines....

Wuz goin on??

I'm sure this is a stupid question, but I just saw two quakes....one on the Northern and Southern mid Atlantic ridge....

a 4.8 and a 5.6


4.8 NORTHERN MID-ATLANTIC RIDGE43.69°N -28.96°W 10Km Deep 2011-04-19 20:30:29 UTC2011-04-19 18:30:29 LOCAL USC0002V2T

Where are these areas?

On a zone in the mid Atlantic that is theorized to produce sea floor spreading. And those quakes could be indications of that or related volcanic activity on the sea floor.

Hi Puterman, thanks for the welcome. I experienced my first earthquake in Crete last year which in turn led me onto the internet to find out more and it has snowballed from there!
I have been reading all your threads on here for a few weeks and I have to say you are great at explaining things in plain English for numpties like myself who have only basic high school knowledge of geology (which was over 30 years ago!)


Thank you also for posting the link as it is very easy to understand as well as being very informative

Did anyone see the strange quake off Bermuda?
It was a 4.4 on 04/18/2011.

This article goes into detail that 7 out of nine earthquakes there
have happened within 3 days of a full moon in the last 25 years.

Nice find,.
I find myself at a watch to places such as Bermuda (being an old volcano)
when they have quakes near them..
