I gave that one to ya.

LOL!!!

6.0 Codrington, Barbada in the Caribbean

earthquake.usgs.gov...

This area is known for having large 7+ quakes

Haven't been on ATS for quite awhile, but still keep a watch on global quakes...gut feeling says that this year so far is experiencing very low quake activity. Is anyone keeping an energy tally?

Morning SJ,

Nice to see you

Puterman has that info on his WS. This is just the link.

Been pretty quiet in NZ since the Yarra River, South Marlborough M5.50 on 14th Mar, scratching around to find any M3's, let alone 4's, even at the Kermadecs.
So when its like this you search around for Swarms.
Those of you who read Geonet may have seen this one WikiteValley-Te Kopia Swarm First part was on 21 Feb, second part further down the valley on 20 March.
I've taken it a bit further, Interactive NZTopo Map and Bing Map, Energy Released ( not much, less than 5 TTNT), and a Timeline Graph here

a fair amount in Indonesia this week, mid 4s

Phillipines also

Ha! I put the TV Cricket Commentators Curse on NZ
"Taylor defends for the 18th ball faced without scoring, then OMG he hits a boundry to the fence for a 4 !!"

Finally a couple of M3-4 earthquakes, ironically near Black Cap hill 769m, close to the Otepopo Fault

Speaking of Black Cap's and Cricket aren't we doing well at the T20 World Cup in India?
BTW Taylor got 36 not out.
Against Pakistan, who also featured the same day on the EQ lists with a M5.5
Maybe it was the foot stomping of the fans back home in frustration when NZ beat them

a reply to: ElGoobero
yeah a few.
I was looking at Geofon earlier, last 23 Global quakes listed were less than 5.
It's only been a day since a 5, but it appears GFZ are going into more detail (lower magnitudes) in their searches a lately, places like Cyprus, Sweden, El Salvador etc

I must be getting old. I can't remember what was up with a bunch of earthquakes, a couple of years ago, near Hawthorne. I remembered that there is a military base near there. If I remember correctly, there isn't fracking near there. But I'm not sure.

Why hasn't anyone mentioned these? I'm paying attention to Mombotombo which at the moment is having some cool tremor after a long pause. It's gonna blow again.

Because I haven't been paying super close attention, I'm not sure but I think there's lots of miro activitiy all thoughtout the south west USA. It could be I'm not getting a good picture because I've stopped using the USGS so much and have primarily been using Volcano Discovery. They all have different sources and nothing ever seems to match another listing organization.

I know why you get frustrated Muzzzy. Oh Muzzy, since I've switch my source, it seems that there are tons of earthquakes near Mexico. Are there always lots and lots or earthquakes off Mexico? I'm making the assumption that many of these aren't showing up on USGS and when I see them in total it only seems like a lot.

Ug. If you can quickly look at your records and sources and tell me if it's busier, or if it's that the the different sources make it seem busier.

Oh, as for Hawthorne, BOMBS maybe???

NW Off Okinawa-jima Is 18-22March 2016Swarm.
not as big number wise as the one 14-19 Feb 2016 further NNE which had 404 events in it.
The new swarm is releasing a lot more energy though, 815.332TTNT for only 24 events, but two of those were 4.9's.
The entire Feb swarm only released 109.378TTNT, as I say for 404 events, the biggest were two 4.2's.
Seems to be a pattern here with double biggest events ( even if they are small in the big scheme of things.
Here is a screenshot of the two swarms location, finger is the new one.

Feb Swarm
March Swarm

a reply to: ericblair4891
OK I'll look at it tonight. I don't usually bother with Mexico unless there is a big one.
have a look here, you might see something yourself, they always show the last 100 events

a reply to: muzzy

Jeez, I should have checked the Mexican sources directly. I forgot they have a pretty good system as I've checked there before when watching Popo. I was asking you because I wanted to see if you could see an increase lately. I've noticed that compared to last week, they have decrease, so I'm thinking, there was a uptick last week. I know they get a lot.

On the other subject of Hawthorne, I found out when the last big swarm was 2011. I'll post an old new article. Interestingly, Northern Nevada picked up slightly. And even Idaho, near Challis had a tiny one.

In the report it said that the 2011 earthquakes were tectonic. And then it explains why. But it isn't always the case that volcanic forces cause long rhythmic- harmonic earthquakes, that's just magma moving. However, if a large amount of magma is moving slowly or expanding slowly, the outward pressure exerted on the hard crust would cause sharp tectonic earthquakes. These pressure events would cause small earthquakes which would then resemble swarms of very small earthquakes. This is the pattern seen in Yellowstone swarms. And, this is the patterns I've seen in Idaho and Nevada.

It's like fracturing, or like the geothermal plants, the pressure of fluids in the crust cause swarms.

In each area, there has been past volcanic activity.

earthobservatory.nasa.gov...

And here's a graph from yesterday's Mombotombo showing harmonic tremor. The magma is moving and this volcano is filling up. I'm expecting it to blow soon.



Oh and to go back to Hawthorne, the epicenters are in a different place. And there's two areas affected at the moment if you add in those earthquakes by the lake.
Ha, and I thought I was crazy, wait, I am. oh well, there's been two more tiny ones in Idaho. As I've been saying, the uptick we just had in Northern Nevada is related to Idaho. I've made that tenuous connection. Not I want to elaborate and say that Hawthorne is also in the mix. Heck, just look around Hawthorne and you'll see the very dramatic past. Volcanic craters everywhere. Heck, we thought Idaho looked like the moon landing site, well, you can find some spots in Nevada that nearly fit the bill.

Let's just say my wildest imaginings are nowhere near true. But let's say some of it is true. Let's say it's volcanic, but not eruptive. Meaning, the magma is moving, but nowhere near the stage to erupt in the near future. Maybe the maybe is just moving around like it does under Yellowstone. A circulation of sorts. Since the crust is thin in some of these western North American parts, that movement is causing stress fractures, and some aquifer heating and circulation. Actually, I think I've written some of these same thoughts before. So, I should stop. I'm just stating that these are connected and due to fluids heating and cooling.

a reply to: ericblair4891
Eric, Not sure what time period you were looking at or thinking about.
I went back to Jan 1 for the graphs below.
The magnitudes are rising slightly (Black 85 day trend line on Timeline Graphs below) and the Daily Numbers Count did spike on day 23rd March (2016 Daily Count Graph below).
So that was probably the increase you seen.
rightclickviewimageforfullsize



Having done that I decided to keep going, back, for something to compare with.
Same time period 85 days Jan 1- Mar24
Did 2015 which had less numbers, then 2014 which had even less, so I just had to do 2013 !,






* The 0 count on the 60th day is due to not being a Leap Year (2016 was), I didn't allow for that, too late now.

Looks like the increased numbers may be due to better technology, picking up more and more quakes, probably those offshore one's,
Also noting not many big quakes in the last 4 years.
SSN Data goes back to 2006, I'll have a look at the rest tomorrow.



I won't go with a whole year graph for Mexico, because the magnitudes are only from 3 upwards, with a few exceptions, the timeline style is just a blur of red dots with a few bumps in it for a 12 moth period.

a reply to: muzzy

Hi muzzy,
I had a question. Did you look into the southern Spain- Mediterranean Sea quake activity? Do you have any stats or graphs on that?
This year has been pretty strange over here in terms off frequency/magnitude of the activity in that region.
I don't recall it to be that often in previous years. Is it possible there is a relation between the volcanic island 'Isla de Alborán'?
I don't know if you have any information regarding or maybe you can link me to someone who has?
Thank you.
I.F.
