This quake got my interest because of the location.
Had a look into the data GNS has and did this piece on the Townsend Fault.
Turns out this 5.178 quake was the 2nd biggest since records began in 1971 on either the Townsend or the Coopers Creeks Faults
The biggest was a 5.238ML on 1986/7/11, right at the junction where these two join together and become the Glen Tui Fault.
It has actually been a pretty quiet Fault.





Probably only of interest to those who know the area

5.8 at Guererro, Mexico

EXTREMELY interesting to me, obviously, as I am just across the bridge from View Hill, in a manner of speaking!! Thank you for answering a question that has bugged me since the 5.2 woke me up last week....

I don't have a good feeling about the Canterbury activity.. now it's worse LOL

5.8 at Alaska Peninsula

5.8 Guerro Mexico as well.

Is it just me or is EQ activity hotting up??

Sky News saying 6.1 off the coast of Japan

reply to post by PuterMan


This is a strong quake and If memory serves me, the Japan 9.1 happened just after Kuril Islands which is on the same plate. This alaska one may shake things a bit

Yep, Japan 6.1 just showed up on EQ map. I always knew EQs were common but the number of them just seems to be higher than normal. And the intensity is def picking up I deel.

Ive decided to post a little about recent EQ activity in Iceland for those interested.





It appears as though things are getting a little busy again, especially around and under Askja volcano.

The earthquake activity in Askja volcano continues to evolve at rather fast phase. A lot faster phase then I did originally expect. Far as I can tell from the Icelandic Met Office SIL data (tremor plots). The earthquakes that are now taking place in north Askja volcano appear to be mostly magma related earthquakes. The strongest earthquake so far did happen today and had the size ML2.5 with the depth of 0.1 km. The deepest earthquake so far took also place today and had the depth of 19,6 km. It had the size ML1.4.

The blog is worth a visit as activity in that area is gaining interest, just another on the list of ones to watch.

Thanks guys!!

I'm looking at both 6.0's (5.8's) here in North America also

ALASKA!!!

And all of these are today!

I have been watching these since the 5.8 in Guerrero, Mexico about four hours ago. It looks like a very active day so far.

It's just you

Nothing out of the ordinary going on at present. Whilst Alaska is a 6, they have them and I have no doubt that an Alaskan will tell you that they eat them for breakfast. The trend for Alaska in terms of earthquake numbers over the past 2 years is fairly flat. These are numbers of earthquakes per month in Alaska. Source: I counted them.

Fairly unexciting when you see it graphed.
