PuterMan, I'm new to this quake subject, and wonder if you would give your opinion. With the latest quakes in a short amount of time, are you worried that Japan may see another massive quake soon? Or is this just stress relieving, and not to worry too much?

You think some missile testing?

This particular area is not quite the same as the Honshu quake being more towards Hokkaido. Whilst the 9.1 encompassed that area I believe that this particular batch may not be directly related to the 9.1

Having said that however this seems to be exhibiting a reasonably normal main shock/after shocks sequence so no I am not thinking this will lead to anything bigger.

As I said earlier in the day there could be what would be termed as a larger quake in the region, up to maybe a mag 8, but that is small fry compared to the 9.1

No I am afraid I don't. Nowhere near Homs and too far inland Lebanon.

Actually it is right on the continental convergent boundary that runs up through there. I guess we just don't see so many there that when we do it looks odd.

Glad someone caught that one
I had gone to work by then.

Geonet had 5.418LML a bit further out to sea than where USGS had it
and a possible 4.381 aftershock on the opposite side of the Caswell Spur

Not sure what Geonet are playing at, there were many Mag 1's on the Geonet Rapid this morning but there is no sign of them on the magma data download.



I have debunked the "there is a 5+ coming to NZ soon because the daily numbers have dropped off to less than 10 /day" myself, but this one seems to fit the theory, with the two previous days only having 6 quakes each day for the whole country. I thought it yesterday, but didn't say anything as its not consistent enough to be right every time.

Another 5+ off Fiordland

Something I haven't done before is 90 days NZ quakes, mainly because there are so many quakes the Google Maps usually freaks out and can't cope with the number of icons.

See how they load for you today, I got them to all load on just now.
interactive 90 days
I wanted to see if I could see any trends, it seemed that activity has moved away from Christchurch over to offshore Fiordland lately. On the interactive map you can click or unclick each 30 day period to see the changes, or hot spots, zoom in and out etc
There was one day (13th March UTC) where no events were recorded in the preliminary data for Christchurch.

Which raises the question " are we done there yet?"
I notice that of the few quakes they are still getting many are not being reported as Felt, is everyone down there " over it"?
For those who are on Broadband the interactive map probably won't load so here is the Christchurch last 90 days, goes back to include the 6.0 on 23/12/2011 at South New Brighton


and heres NZ for the last 90 days (thumbnail, click for larger image)


Also quite handy to see the Faults in my "Bay", some are obvious, some are not so, looks like some may join up to be continuous.
eg the Taranaki Fault looks like it keeps on going south, and the Manaia F and Taranaki F seems to have another cross fault at the south end, which may be an extension of the Wanganui Basin Fault Zone.
That "unnamed Fault" probably does have a name, just can't think of it right now, thats where the bigger quakes seem to happen in my area, incl a couple of 6's in the past 16 years.

Thats a pretty bigun for the suburbs of Rotorua, deep though, no felt reports
Officially 5.01ML, not a mag 4.9 rounded up.

EMSC has 3 logged for that region and they definitely look individual by the locations and times - unusual to see 3 together in such quick succession imho for that region.

Make that 4 including this one just in - quite a ...dare I say it ? Swarm !
