Quake Watch 2011

reply to post by muzzy


Thanks Muzzy. It's hard to get a true picture of what's happening over there with limited data. Still nothing smaller than a 2.5 on that site.
By the way, keep up the good work with the interactive maps. They are so interesting to look at and keep track of.

The 2 islands are twisting against each other.
Not good.

Theoretically going by the depth of 12km this would be on the Australian overlaying Plate, not the Pacific Plate that Christchurch is on.

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.

I would just like to note for the record, we just had a new moon, and just hours ago, we reached apogee.

There's a correlation.

Just to put it out there a CME is also due to hit the atmosphere today.
We are picking up a lot of distant areas on CB and Ham radios today.
Unusual as it usually causes skips in transmission.

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

Brain fart.

I was sure I'd seen one with 4.9 but now can't find it. Put it down to exhaustion

A couple of them off the Oregon coast now:

There was a 4.9 down by Auckland Islands a few days ago Aoraki.

And the correlation is what exactly????

I've been tracking this for some time now and I can't see any connection at all.
Check out this graph.
It is comparing Mag 6+ quakes with phases of the moon for 2011 so far.
Data for the quakes is from Geofon (because their system is easier to use, and they downgrade less, but that doesn't matter if its a 6.9 or a 7.0 in this case)
The Moon Phases are from Fourmilab

To make the graph work I had to give the time axis in Year Day Number (1-365) which can be obtained from Time&Date calender



There is a Full Moon, a New Moon, Perigee and an Apogee once a month every month.
So the quakes are all over the place, there is no "trend"
What people do is forget the ones that happened in between the phases and only remember the ones close to a phase.

I know there are a few people out there eg Ken Ring and also Jim Berkland for example, who run with this Syzygy thingy, but my research says its a load of rubbish.

I'll have a go at 2010 as well just to confirm or deny once and for all.

BTW 2011 looking pretty quiet for 7+'s so far only 3 (4 if you count the Argentina 1/1/2011 6.8 which USGS gave a 7.0)

Has anyone looked at 1993 (the previous Super Moon) to see if there was any uplift in geological/volcanic activity??

reply to post by lasertaglover


I have friends in Yachats, Or. Use to live there.
Better give them a call - significant quakes but
some distance away Thanks.

Isn't the moon ALWAYS there rather or not you can see it?
I wonder where the position of the moon actually is in regard to the earth during these times.
Cause sometimes you can see the full moon in the daytime and sometimes at night.Doesn't it orbit a little faster or slower then the rotation of the earth?
