Quake Watch 2011

reply to post by Shenon


Hi Shenon, no I haven't but that quake is right underneath an unnamed volcano.

Unnamed, East Gakkel Ridge
Volcano types: Submarine volcano Summit Elev: -3800 m
Latitude: 85.58°N, Longitude: 85.00°E

Two young volcanoes were discovered along the eastern part of the slow-spreading Gakkel Ridge during a bathymetric survey from a submarine in 1999. The westernmost volcano showed evidence of highly reflective, sediment-free surfaces and young faults overprinted by lava flows. During January-September 1999 global seismic networks detected an earthquake swarm corresponding to the approximate location of this volcano. The correlation between the locations of the earthquake epicenter locations and the strongly reflective, untectonized western volcano together with the volcanic character of the seismic record provided evidence that lava erupted on the East Gakkel Ridge within days to months prior to a May 1999 submarine survey (Edwards et al., 2001). Because 12-kHz sonars can penetrate through thin sediments covering acoustically reflective lavas, it is possible that no eruption occurred on Gakkel Ridge in 1999. Historical global seismic records indicate that this was the only earthquake swarm detected on the Gakkel Ridge in about 100 years.

This is also in the gas fields! Are they drilling yet does anyone know? Need a new blog "Fracking Santa"

@ Shenon - Apart from the pressure being up abit, it looks normal.

I'm glad you guys are looking at the Arkansas quakes. I do believe the that the soils above the shale strada saturated. This is obvious when you account for all the precipitation they've had in the region this winter. The sandy soils will swell and absorb great quanities of water.

But would this speed up the velocity of the waves?
I don't know. It's obviously the reason these quakes are felt even when small, and the bigger ones are felt over a wide area, is because of the sandy soils allow the waves to pass without any resistance.

And let's not forget the injection. This a contributing factor. I don't think the fluid they are pumping is finding it's way directly to the surface, because you'd see deeper quakes getting shallower. The quakes are shallow. Something else is happening, I just am short on ideas to explain what you're seeing.

I guess its hard to know what's going on down deep under Greenbier at the moment. I know you guys may not have an answer. But at the moment, I know the geologists involved don't have an answer for that question either.

Could the quakes and the injection causing fluids and gases to migrate upward? Like osmosis in a sense. Maybe they are accumulating in pockets nearer to the surface, and then moving through factures before nearing the surface.

Since you guys love quakes, and can do the analysis, maybe you could look at the swarms in Enola Arkansas. I read that there may be enough evidence in the data to suggest fluid movement as a cause.

A comparision would surely put things in perspective.

I should add that the trend, the ENE trend for the fault is the same as Enola.

This one felt huge - everyone had it pegged at at least a 5.0 and were gobsmacked when Geonet reported it as a 4.8!! USGS has it at 4.5!!

Felt widely across a very large area.

I certainly hope it didn't cause any more destruction
or injuries. Stay safe.

reply to post by MoorfNZ


It certainly felt like a 5 here in Woolston and was more violent than the 4.9 a few days prior. A very loud juddery rumble followed by some reasonable sideways shunting.

We have had some rain now and it'sstill falling. The streets are getting slippery and there is increased potential for the inundation to further compromise the integrity of hillslope sections.

Greece Last 7 Days

New Interacitve map for our Hellanic friends
NOT based on EMSC, the data is from NOA, the locals. They have recently started listing micro quakes, used to be just Mag 2 up
Can't get any Felt reports though, its mainly a technical source.

I see zenius picked up on the Crete 5.2 on the 28th , I missed that one at the time
www.abovetopsecret.com...

I found some links to significant Greek quakes from the Earthquake Engineering Research Institute and put them under the map, quite interesting.

any one seen this ? poland isnt often in the news for earthquakes is it ?

6 quake strikes Kamchatka peninsula in 24 hours

Kamchatka, Russia contains about 160 volcanoes with about 29 of them currently considered as being active. The quakes which have rattled the peninsula were a 4.7, a 4.9, followed by a 5.0 and a 5.1 and a 4.7 and a 4.8 - so there seems to be a gradual increase in intensity and activity.

Any thoughts on this?

4.9 a few days ago

Can't find one, there was a 4.6 on the 1st March NZDT (28th UTC) at Governors Bay, is that the one?

Can't really compare the Peak Ground Velocity between the two, no two same seismo stations PGV readings available for both quakes.
PARS Panorama Rd has 1.43859 cm/sec for last nights 4.8
and
MQZ McQueens Valley has 1.17254 cm/sec for Tuesdays 4.6, and the seismo is further away too.
Looks pretty normal.

Yeah I know "there have been so many"

Location probably has a lot to do with it too, being west of the Port Hills, they must absorb some of the energy from the Lyttelton side aftershocks

reply to post by TopsyKretts87


Ya know I have been quake watching for 4.5 years now and have noted that it is pretty rare that quakes gradually increase in size during a series to have a bigger significant quake (6+) hit as an end result.
It does happen, but its not the normal chain of events.
Its probably just a Swarm.

Has anyone noticed the continual 3.5 and up magnitute quakes in Southern Iran? When I did the search there were no smaller quakes. Is that because there are none, or they aren't being recorded? I find it strange that they never seem to get under a 3.5 or above a 6.

Re Greece and Italy regions, I think these are areas which have huge potential for catastrophy. Thanks Muzzy for the link to NOA.

heres the page I look at for Iran. They don't post anything below Mag 3.0, same as Turkey.
International Institute of Earthquake Engineering and Seismolgy (Iran Geological Survey) link

They seem to get their fair share of 5's but compared to Pakstan not many 7's

The last 7 was in 2003, near Bam.

About 31,000 people killed, 30,000 injured, 75,600 homeless and 85 percent of buildings damaged or destroyed in the Bam area. Maximum intensities IX at Bam and VIII at Baravat. Felt (V) at Kerman. Damage estimated at 32.7 million U.S. dollars. Surface ruptures associated with the Bam Fault were observed between Bam and Baravat. Landslides occurred in the epicentral area. Believed to be the largest earthquake in this area in more than 2000 years.
