Hey Muzzy - those Kermadec quakes are getting closer and closer !!

What is going on here!?





The rest of the graphs look the same.

yeah that last one was well inside the Geonet search area, but Geonet show nothing on the download for 21st Dec. I still haven't figured out why they don't put these on their lists, the stations used to get the readings at USGS and Geofon are New Zealand stations (as well as others in the pac islands and australia)
Looking at the phase data for that one, this is what they both start with (simplified version)
USGS
STATION CODE, LOCATION, ARRIVAL, MAG
URZ, Urewera, East Cape, 18:32:41.78, 4.7ML/4.3mblg
BKZ, Black Stump Farm, Hawkes Bay, 18:32:54.83, 4.9ML / 4.1mblg
OUZ, Omahuta, Northland, 18:32:55.76, 3.9ML
HIZ, Hauiti, Waikato, 18:33:02.34, 4.5ML
BFZ, Birch Farm, Eastern Manawatu, 18:33:11.49, 5.2ML

GEOFON
STATION CODE, LOCATION, ARRIVAL, MAG
URZ, Urewera, East Cape, 18:32:42.7, 5.4ML
BKZ, Black Stump Farm, Hawkes Bay, 18:32:55.8, 5.1mb/ 5.4ML
OUZ, Omahuta, Northland, 18:32:56.8, 6.1mb/ 5.6ML
HIZ, Hauiti, Waikato, 18:33:01.5, 5.3mb/ 5.1ML
BFZ, Birch Farm, Eastern Manawatu, 18:33:14.3, 4.9mb/ 5.6ML

If you look carefully at each one they ARE different, these are the individual station recordings of the Bonin Islands 7.4 quake this morning NZDT

My county had one last night, and that is unusual for us, first time in my 30 years I have ever felt a quake.

Even made a thread, lol

What I meant was the other graphs are showing the same activity. How do these stations from all around the world go off when there's one big quake somewhere. I guess what I mean is, how is a quake able to set off a sensor on the opposite side of the world. I don't know how these things work (obviously). It's no secret that earthquakes aren't my specialty.

because the shock wave passes through the earth, not around it.
If you compare some of the stations closer to the epi-center ie IU/MAJO, Matsushiro, Japan, with one far away ie IU/TRIS, Tristan da Cunha, Atlantic Ocean you can see how lighter the TRIS waveline is.
Most quakes over 6.3 show globally.

The UK has hundreds of quakes each year - they're just so small most aren't felt. There was a 5.2 c. 2008 in East Anglia region.

I used to live in the UK - but moved to somewhere with proper earthquakes

Yes, you could see the ghostly trace on the Geonet drums from the Bonin quake - from north to south of the country.

Thanks for the stats.

Ok, so we all know to expect thousands and thousands of aftershocks after a quake as hefty as the recent Bonin event... but... is it just me or has this quake set off rather more larger (5.0+) aftershocks than usual? I don't remember seeing such a long period of large events after the Baja/Chile or even our own New Zealand one... Anyone?

I was thinking the same thing, but am only new to the game so we'll have to wait for an expert opinion. 16 our of 63 under 5 mag since the biggie. The rest in the 5 range but none bigger. I suppose if they were in the 6es I'd be more worried.

You need to consider the topography. Take Baja, this is on a fault zone and produced one big one and several smaller ones. A similar thing happened to Haiti but with many fewer aftershocks.

Now look at Chile. There was a big one and then a whole series of big Mag 5+ events following it. What was the difference, and how are Chile and Bonin similar?

Both are in subduction zones, which did not apply to Baja or Haiti.

Just my 2c

Cheers Puterman - I knew there had to be something about the location/tectonics but didn't make the connection

I recall some time ago your were proposing NZ as an ark, but how about Ireland?


The whole of Ireland is practically free of earthquakes. This is clearly a real phenomenon and not a product of reporting - one writer, as early as the 17th century, remarks in describing an earthquake (probably Welsh) felt in Dublin in 1534, that an earthquake is such a rare thing in Ireland that when it happens it is considered a wonder.


Seismicity and Earthquake Hazrd in the UK

Anyway the point of replying was to say hundreds? No I don't think so. Maybe 100 in a good year. Having lived all around the UK for over 50 years and pretty much all of that in the RED zones of the seismic hazard map in the article until I moved to Ireland - into the earthquake free zone and above the max sea level rise - I can honestly say I don't ever remember once feeling an earthquake and only very very rarely remember them being reported.

Also from that article:


One can therefore draw the following conclusions about average recurrence - the UK may expect:

* an earthquake of 3.7 ML or larger every 1 year
* an earthquake of 4.7 ML or larger every 10 years
* an earthquake of 5.6 ML or larger every 100 years.

There you go. Have a read of this page on my site and it might help you understand how this happens.

I made this page mainly as a response to the "I don't understand how these earthquakes are going off all over the world" scenario so I hope it does the trick for you!

There have been 12 quakes recorded in the UK in the last 30 days - so averaging that out that would be over 100 this year? I'll remove the 's from my figures in future

The thing is that I have also seen that page with only one or two on it as well.

Just noting that 5 of those are off shore - some quite a way off shore. In fact the Norwegian ones are right on the Norwegian coast line. I think it is a takeover bid!
