edit on 8-1-2013 by MariaLida because: (no reason given)

No problem the more info the better

If you say so my friend, will post this also because I know you will be interested ..

Think possibility in next days for one more strong EQ of M 7.5 + somewhere on sensitive areas of "Ring of FIre", probably in next 4 days to 13 January or max to 18 Jan ..

Before 3 days we had a EQ offshore M 7.5 SE Alaska, British C. - North of Cascadia Subduction Zone

seems to be picking up all over

You are the quake map god, Muzzy!

The Carlsberg Ridge is hopping tonight between the Seychelles & Maldives islands:

It's hoppin' everywhere today, it's like there's a rad subterranean party we're not invited to going on

Edit: And another one for Carlsbeg, a 5.0 this time. Added above.

That Burma/India quake seems to be dropping to 5.9, 0nly EMSC and GFZ are sticking to 6.0, all the rest dropped while I was having dinner, even the Thai/Burma site went down a point.

reply to post by Nyiah

thanks , I try my best, the more I do the easier it gets. If the Networks laid the data out in the same format it would make it easier .
BTW a typo error on that post, there were 1188 quakes on the map not 188, obviously

Carlsberg Ridge/ Kermadecs/Burma/ Carlberg Ridge........ see a connection yet?
they are all on the outside edge of the Indo-Australian Plate ..... expansion?
See the temps in Aus? geez 52 degrees Celcius in the Centre, how could you bear that eh?

haven't seen much from Indonesia lately ......

So far still going strong at the Carlsberg Ridge

reply to post by dreamfox1


Yeah, it's still shaking steadily there. I'm pretty surprised, I thought it would have ebbed by now. However, I don't think it has anything to do with plate break up, but more like plate creation. The Carlsberg Ridge is a divergent boundary, where the plates are moving away from each other as opposed to one subducting under the other.

The area history maps on the USGS data page for these quakes do show quite a good amount of earthquakes over time. I guess this is one of those times where the area has a birth pangs fit.

reply to post by Nyiah



Yea i just hope it stays with that size of quakes

Its a no brainer. Look at where they reside. Right on the plate boundary. Its happening as we speak. Movement on the left ,movement on the right. The recent swarm at 10 km deep, all of them. 6 miles.

last year locally to this swarm.

Historic Earthquakes
Magnitude 7.6 CARLSBERG RIDGE
2003 July 15 20:27:50 UTC

earthquake.usgs.gov/earthquakes/eqarchives/year/2003/2003_07_15.php

This earthquake occurred on the Carlsberg Ridge, a mid-ocean ridge system that is located in the Arabian sea between India and Northern Africa. The ridge marks the boundary between the Indian and African plates and near the epicenter the Indian plate is moving away from the African Plate at a rate of 33 mm/yr in a northeasterly direction. The Carlsberg Ridge is a slow-spreading ridge with rough topography and a depth that varies from 1700-4400 meters.

Mid-ocean ridges are divergent plate boundaries, where two tectonic plates move apart from each other. New oceanic crust is formed as magma rises up between the two diverging plates. Active spreading ridges are offset by zones known as transform faults, where plates slide horizontally past each other neither destroying or forming crust. This gives the plate boundary a zig-zag pattern. Ocean ridges represent the longest, linear uplifted features of the earth's surface and are marked by a belt of shallow earthquakes. Earthquakes can be caused by the release of tensional stress in the uplifted ridge or by the horizontal movement of plates along the transform faults.

Abstract

Keywords:

seismology;
tectonics;
Indian Ocean

[1] Analysis of broadband seismograms from the 15 July 2003 large earthquake (M 7.6) in the central Indian Ocean reveals an unusual source process. The source duration of longer than a minute is more than twice as long as expected from earthquake scaling relations, yet ∼80% of the moment release occurred in two energetic asperities near the end of the rupture. These two asperities were located in lithosphere with an age of 7 Ma or greater. A previous study has suggested that strike-slip earthquakes in oceanic lithosphere having much longer than expected source durations also have a slow, dissipative rupture process characterized by low radiated seismic energy (and therefore low apparent stress). We find no evidence for a slow rupture process to the 2003 earthquake. Instead, the long duration appears to be due only to nucleation close to the actively spreading Carlsberg Ridge, in lithosphere younger than 7 Ma. Younger oceanic lithosphere may be able to generate small to moderate earthquakes but be unable to sustain slip in a large event due to steady release of strain in aseismic creep events. Large strike-slip earthquakes within oceanic lithosphere may occur only in the central portions of long transform faults or in intraplate regions, rupturing energetic asperities like those that failed in the mid-Indian Ocean earthquake and leading to the observation that oceanic strike-slip earthquakes have the largest apparent stresses among the global population of shallow earthquakes.

Measuring small tremors in the Pacific Northwest

Cascadia quake simulations

Stanford geophysicists are well represented at the meeting of the American Geophysical Union this week in San Francisco. Included among the many presentations will be several studies that relate to predicting ­– and preparing for – major earthquakes in the Himalaya Mountains and the Pacific Northwest.

The AGU Fall Meeting is the largest worldwide conference in the geophysical sciences, attracting more than 20,000 Earth and space scientists, educators, students, and other leaders. This 45th annual fall meeting is taking place through Dec. 7 at the Moscone Convention Center in San Francisco.

edit on 9-1-2013 by MariaLida because: (no reason given)

"Maybe a dumb question" But why would she have trouble getting date from actual eathquakes in the casscadia area? Is she refering to the lack of monitors off shore?

The Planet seems to be going through an expanding phase this last week
maybe I'm being selective, but it did jump out at me from the lists over the last 5 days
Carlsberg Ridge
Pacific-Antarctic Ridge
Southern Mid Atlantic Ridge
Mauritius/Reunion Region
Queen Charolette Is/Fairweather Fault
are all on Transform or Rift Faults
and this one that almost got missed
Ryukyu Islands


I almost missed it, watching o/s Honshu too much
It had 55 aftershocks, minor/micro sizes admittedly, but thats quite a few for a moderate quake under the ocean
(thumb, click it).

Tokara Islands 5.4 interactive map here

Note: for those that aren't sure about the plate boundries, open that link, zoom right out and then have a play around with the Plate Boundries check boxes in the left hand column, click them all off, then click to see each one as you wish. ie see all "Subduction ones" or "Rift Boundries" etc

especially relevant to those who post on other threads "OMG the Cascadia is going to rip" when the quakes they are talking about are not even on the Cascadia Subduction Fault


edit: BTW "NIEDr" on the table the "r" stands for reviewed, I'll try an remember to mark "r" or "p" as it is relevant, the preliminary data in this case was not available as the p coverage doesn't usually go that far south, just the main 3 Japanese islands of Kyuku, Honshu and Hokkaido, hense a 3 day+ delay to get the "r" info.

reply to post by muzzy


You know, I noticed the areas, but didn't think "expansion". Now that you mention it, it does make sense. That makes me wonder about the subduction zones. Now that there's activity in the "extrusion" zones, how much extra pressure does that translate to on the subduction zones? What comes out must go back in, after all.

reply to post by Nyiah


yep it will be interesting to see if there is an upsurge in quakes on the subduction boundries in the next few days.
It might not even take that long,it could be today.
LDEO is the best map to see them all I think.
LDEO not known for their pin-point accuracy as to Lat/Long, so those Mabahiss Fracture Zone (Carlsberg Ridge) quakes are all on top of each other , but good for an overview of the whole planet.

Fiordland, NZ, Philippines, Indonesia, Sandwich Is. and Chile subduction zones haven't had a 5+ for a while.

There's your 5+ on the zone in Indo Muzzy! Ok, just a 5, no +, but still.

i felt a 5.8 here in canberra this morning...dont panic...i was in questacon (science museum).

they have a purpose built house that gives you the impression you are in an earthquake and what it feels like. very realistic...floor moves and the kitchen has things falling down etc.
