It looks like mexicalli had a 4.0 a few mins before that one too.

we were just on the phone with my husbands grandma who lives in El Cajon- near San Diego CA, she said there was just an earthquake. But my husbands mom who is here with us said it couldn't have been a very big one. I haven't looked on the msm news yet to see anything. I figured it would be posted on ats, but i didnt see anything yet.

The SoCal 4.8 (edit: downgraded to 4.4) felt by my friend in San Diego - she said "was a jolt, then a roll and a "rumbly finish"".

They can't seem to make their minds up - first it was changed, then the 2nd 4.4 was removed and now they are both back as listed:

Today is a very active day. within 6 hours there were 10 medium-sized earthquake, and a strong earthquake (6.3)

and 3 EQ's in California....

whats going on today?

Hey there everyone,

Let me begin with an appology ... as an interested novice where earthquakes are concerned (long time since I did a sceismology / volcanology module amongst the rest of my Natural Earth Science studies) ... I have noticed something very interesting concerning 'ALL' of the earthquakes that have occurred in the last 24hrs.

When I checked the sceismo on my computer today my relatively naive eyes picked-up on something of a pattern (see below - starting with the biggest and moving around in a clockwise motion);


Nicobar - 7.7 / 5.3 / 5.1 / 4.7

Ryukyu - 5.3

Honshu, Japan - 6.1

Komandorsky - 4.8

Alaskan Peninsula - 5.0

S. California - 4.4

C. Mexico - 4.9 / 4.6

C. Bolivia - 5.0


Ok, so the thing that I noticed ... which may mean nothing but I found it interesting ... is that all these locations are either coastal mainland or islands off the mainland ... and they all sit around the rim of the Pacific Ocean.

www.iris.edu...

Is it normal to have the entire collection of earthquakes in a 24hr period all focused around one specific body of water ?

Is there some extra significance relevant to the tectonics of that area ?

Please tell me to sit down and shut-up if this is a relatively common event.

I just thought I'd mention it.

Woody

Basically the ring of fire is a very seismically active area and in any given day the chance of having quakes around the rim are high.

Proportionate to the number of quakes daily the rim has the most and thus will always show up. I think I would be more worried if there were none!!

What I did find curious is that yesterday there were 8 x 5+ quakes which is more than twice the average and actually over the month so far the daily average feels higher, despite having none on the 8th. Actually it is 3.833 for June so far so not a biggie, but we shall see.

reply to post by PuterMan


Hey there PuterMan,

Thanks for the reply. It was actually the strength of the quakes around the Pacific rim that struck me as much as the position. I have noticed that as you mentioned there is always a fair bit of activity there but more often than not they are 4 mag or less.

And I personally have never seen a display like that where all the quakes that occurred were only in the Pacific region ... I thought it was quite anomolous.

I shall be keeping an eye on this.
