I would gladly try to help if I know the question in your mind.
That whole Eastern part of Central Africa is actually very active.
I would say even more so than for instance Califirnia or Indonesia.
Though most quakes are in the 0 to 4 R/Scale range.

There are two main belts where it seems Africa is splitting in three.
(Actually I dispute this because there is a third much older rift also running from Morocco through the center (Lake Chad) to Lake Albert and then through Zambia (Copperbelt) to Swaziland.

First one is well know - The Great African/Nile Rift Valey that starts near Alexandrial and ends in Swaziland; this is well defined through the Nile river and Lakes Albert, Edward, Kivu, Tanganyika, Mweru through N Mozambique to Beira.

The other main rift (youngest) is the Eastern Rift Valley defined by a string of very active volcanoes - many last active in the past 500 years. (Including my favourite Nabro) They are the ones starting in the Red Sea (some say Israel/Syria) and running through to Zanzibar in Tanzania.If you use Google Earth Center on Lake Victoria and zoom out to about 3,000 Km you can see both Rifts.

Now to what I assume your questions might be:
a) The recent quake in Tanzania is very normal. It is just catching news madia and people attention less than for instance CA or Japan. Much lower 'Technology Advanced Polupation' ,ight be a reason. Google Earth do have the EARTHQUAKE feature, if clicked you can get quite a historcal view.. 1993, 1996, 2003, 2008, 2012 - all 5+ within 10 km.
b) The other potential question is about the 'Grinding' you marked in Lake Malawi - this is not strange either. Back in 2009 there were a swarm of medium to small quakes but nothing serious about it.

Both the two rifts are very active; more active in Central regions.

I have a trick question: How many volcanoes are then in Africa?

Only one quake in the US in the four hours since the 6.4 in Alaska?
Weirdly quiet! And no aftershocks???

earthquake.usgs.gov...

Sup with that?
WOQ

Just had a 4.5 aftershock!
Still too quiet though! (Cue spooky background music....!)

hi all...

i just noticed this in another thread...

www.abovetopsecret.com...&addstar=1&on=15045853#pid15045853

and thought i would throw it in here for opinions...

they are referring to the APRIL 11 E/Qs and the possibility the Indo-Australian plate is splitting...

In another new study, Fred Pollitz at the US Geological Survey in Menlo Park, California,
and his colleagues found thatthe global rate of quakes with a magnitude of 5.5 or greater increased almost fivefold in the six days after 11 April- something that has never been seen before,
even after very large earthquakes (Nature, DOI: 10.1038/nature11504).

"This was the most powerful event [ever recorded] in terms of putting stress on other fault zones around the world," Pollitz says.

see this link from new scientist...

www.newscientist.com...

i find the first part of the above quote interesting, as it is a subject long debated on ATS,
and the second part of the quote surprised me...the "most powerful... ever"

Really, splitting up. How? It already is two.

I don't know where the nonsense comes from but people should investigate more and should never listen to grant chasers scientists without a huge dose of suspicion.

You only have to look at the plate boundaries in GE to see that the Sumatran quakes were on that boundary that divides the Indian and Australian plates which are two separate entities.



Personally I would sack those so called geologists who stated there was a 5 fold increase for 6 days after the 11th. You think I would not have noticed that. Either they are incompetent of are just plain lying.



At the very most it went from 6 a day to 8 a day for two days. As for never been seen before, what the hell is that



Idiots, buffoons, grant chasers and numpties. Sack the lot of them.



I was so steamed up about these jerks that I just had to waste an hour dong what they obviously need a course in - using an Excel spreadsheet. Taking the ANSS data from 1990 to present there are 1.32 Mag 5.5 earthquakes daily on average. The only 5 or was it 6 fold increase was actual an 11 fold increase on the day of the 11th when it went to 10x. At no point was there a sustained increase of 5 or 6 fold for a period of 6 days, or whatever they were saying.



I can't be bothered to go back and look at Japan, but I bet I would find it there.

These people should not be allowed to speak to the media. They open their mouths and totally unsubstantiated excrement comes out. Is it any wonder the populace runs round crying the sky is falling in?




The figures if you are interested

Ha Ha en.wikipedia.org...:Volcanoes_of_Africa

I was meaning that this seems to be very distant from the rift boundary but then if as you say there are many smaller quake we are not hearing about this may explain the apparently strange three of four mag 4 quakes a year.

Are you aware of any source for these smaller ones?

Thanks for the response by the way.

Tanaga volcano webicorder went nuts, could this trigger the eruption? Currently 2 volcanoes are active there, Cleveland and Little Sitkin

I've given up archiving Felt reports since Geonet introduced their new system, half the time the events recorded on the "Felt" page don't have any reports on the map at all. Useless .
example
www.geonet.org.nz...

Geonet SeisComP3 blunders

5.6 down to 2.7
6.4 down to 3.7
at least they had the balls to admit to it
info.geonet.org.nz...

the title of the item is "Fast vs Accurate"

personally I'd prefer accuracy.

Just e-mailing them now to find out what the criteria is to have a quake "reviewed"
the number of reviewed quakes is creeping up slowly since the 17th Sept

Hello Everyone,
I hope you're all better than me, but thanks for the thoughts, I never really left. Just been reading, not writing. Slightly brain dead.

This thread is great because you can go back in time and read our thoughts and find most the quakes laid out in a sort of blow by blow account as it happened. I didn't want to read it but did.

I do not want to argue in favour of the USGS. Gosh, I'm anti-establishment by design, or rather, by genetic design. The rebel bee. So, I checked again and The USGS page confused me because they mention it's an "extrodinary" amount of 4.5M worldwide following the 8.7Mish. Then in the article about the paper, the diagram should remote quakes of 5.5M+. Also, it doesn't show a fivefold increase. It shows a doubling when comparing before and after. Which is a 100% increase.? Twofold? So. forgetting the guys in white coats, I remember, and read and at the time I remember there was a lull followed by a flurry worldwide in all kinds of locals. The argument for remote triggering gets wearker the further out we go and I won't argue 6 days. The whole year was realtively quiet to that point. The fall barely in the average range. It was quiet. The bada boom.

I would focus on the short period immmediately following the 8.7M many of the quakes following were triggered by Sumatra. Hell, I'm not arguing it was even the Indian continent. At the time it seemed like the earth had a swarm of quakes. A storm.

I agree Alaska is active.

But what do I know. After that larger Alaskan quake I started to think Yellowstone responded. It wasn't much of a response if it was more than coincidence..

One other thing I noticed when I read our musings back last April, it was that the earthquakes come in pairs. Just before the 8.7M "mainshock" I wrote that I noticed there was a slight increase and it seemed to me they were coming as double tps. The quakes afterward were moments apart and came in pairs. There was a pattern which I obviously noticed beforehand. The day before the 8.7M I called the activity "the unbearable silence within the earth." It was tense.
Puterman said that he told us all it was going be a quiet year until the 8.6M... I can't remember his specific reasonins for that prediction. I didn't go back too far. Hmmm


i'm okay- ik saw a blad eagle today along the Welland River. maybe they're making a real comeback...

Because I look at statistics, and cast eye of newt and tongue of toad into a cauldron whilst muttering incantations to Mother Earth, and then put my finger in a large bowl of custard and guess.

I said there could be an 8.5 and that there would be about 16 Mag 7 and 120 mag 6, the most recent utterance being here in May.

I may be a little over the top on the Mag 7's but time will tell.

Hi PM, read your rant about the so called 5 fold increase being discussed by so called 'experts' and see a thread was started about that yesterday, and being bought HOOK-LINE and SINKER!

Quakery

You might need to drop in there and RANT

Page 2 linked back to my rant actually.

Can't be bothered explaining it any further to people who don't want to listen....Not enough doom........need doom.......where is my next doom fix coming from.........

Pah!

But there were 2-Magnitude 8+ EQ's , an 8.6 and 8.2. That second Mag 8 makes up for a multitude of 7's in energy release, no?

From the phase data mb = 5.6 (161) That is ~5.9 Mw. The other values can be ignored - too few stations.


Potsdam 5.8 (Automatic)

And now scardec (automatic) just in 5.8 Mw

reply to post by Olivine


Yes it does. But I was not looking at energy release. After all 16 Mag 7 quakes could be 16 x 7.0 or 16 x 7.9 - a major difference. (32 petajoules to 716 petajoules - the difference being about 3 x Mag 8.4)

I said 8.5 and there was an 8.6, and the difference in energy is about an 8.25. There are about 11 Mag 7.5s in an 8.2.

Somewhere, and I will have to find it, I think I did venture a figure for total energy release, in the which case I would probably be in error as the 2 x M8 took care of that. Maybe next time I should use eye of toad and foot of newt - it may be a better combination.
