just noting that there seemed quite a few deep quakes south of Fiji in a similar situation tectonically speaking (both in Back Arc Basins)

Seems like theres a significant swarm happening in Iceland right now, im sure its nothing to worry about, just bringing it to peoples attention.

Thanks for the additional detailed info. Perhaps i ought to leave earthquake reporting to the resident experts lol!

Big one!

I wonder how much it will get changed up or down?

reply to post by Anmarie96


On EMSC this looks as if this is the same quake

Magnitude mb 6.3
Region OFFSHORE BIO-BIO, CHILE
Date time 2011-02-11 20:05:27.0 UTC
Location 36.41 S ; 73.24 W
Depth 5 km
Distances 38 km NW Talcahuano (pop 252,968 ; local time 17:05:27.9 2011-02-11)
33 km NW Tomé (pop 46,698 ; local time 17:05:27.9 2011-02-11)

Big difference. Who will make the first move?

Looking at the phase data I am guessing from a quick eye over that this is going to end up as a 6.5/6.6

You were quick on your feet

Split over 2 areas. At least neither in the area of current concern!

The Hengill one is interesting.

EDIT

Hm! Hekla - Just wind I think.

I seen the same thing

usgs phase data has
mb = 6.2 ( 44) ML = 6.9 ( 4) mblg = 5.5 ( 3)

just to be different Geofon has 6.6

the Russians haven't posted it yet (when I looked)

EMSC now 6.8

I did not expect that. Looks more of a 6.6 to me. Just beginning to appear on LISS



This will undoubtedly have set off several microquakes in the Californian hydro extraction areas.

USGS dropped it to 6.8

Thats a relief, I'm just catching up with 4 days of NZ quakes backlog since got our modem router replaced, haven't got time for a 7 to have to load to map and charts on my World 7 blog right now

Been a bit of action down Puysegur Trench/ Solander Trough, 3's and 4's last few days

Why would there be?

There is nothing out of the ordinary about this.

i posted this on another thread but it belongs more here..

the Sun released only 2 cme's this February, doesnt seem though powerful enough or fast enough to have influence on the latest 4 Chilean quakes
