Quake Watch 2011

I told myself if there was another 6+ Mag on Monday I would start to worry.

Well, maybe it's that time? That's 4 days in a row with a 6+Mag. Usual?

If you take out Japan 9.0 this year and Chile 8.8 last year then no its not so usual to get a run of one every day all in different places
I downloaded mag 6+ data from ANSS 2000-2011 and just doing a quick visual of the dates going backwards found this in 2009, only 2 of these quakes are in the same place (marked with a *),
so 11 Mag 6+ quakes in 6 days

DATE, TIME,LAT,LONG,DEPTH,MAG
10/10/2009 24:38.5, 47.85, 152.46, 112, 6.0
11/10/2009 12:13.5, -22, 170.25, 10, 6.0

13/10/2009 38:05.3, 2.93, 128.23, 32, 6.0

15/10/2009 48:21.9, 3.27, -103.82, 10, 6.0
16/10/2009 52:50.8, -6.53, 105.22, 38, 6.1

nothing really bad happened until Chile the next year.
27/02/2010 34:11.5, -36.12, -72.9, 22.9, 8.8



and those 11 on the run were after the Samoa 8.1

4 days, 500+ small quakes swarm, depths from 5km to 15 km.


The Canary Islands Government has said it is monitoring an earthquake swarm on the small island of El Hierro where in excess of 400 tremors of low magnitude have been recorded in the past four days.

Blimey, that's the one which "they" think could stick half a mountain into the sea is it not. Surfs up, maybe....watch this space.

I like that

You do a better map than me but together we make a good team even though we are on opposite side of the world.

By the way folks the USGS site is not putting all the maps up at present - seismicity, location etc so I can't complete the last two 'packages' yet. Hopefully they will have it sorted later today.

Hi folks,

Just thought I'd ask if a 4.2 in Canada is a strange one to pop up. Seems to be a lot of things going on today, someone in another thread is claiming to have a prediction of a mega quake being only hours away. Anyway, here is my source.

This probably isn't a very reliable one but hey ho that's what I watch.

Peace to all.

Thread that has the prediction incase you missed it

WOW! This is some good information and something worth while to keep an eye on. Giant Wave for the East coast of America is possible if the surrounding Volcano erupts?? ( I read).

They get quakes there all the time.

There was a Mag 7.4 in 1933 a bit further north

Date/Time: 1933/11/2 23:21:32
Lat: 73 Long: -70.75
Region: Baffin Bay, Canada
Mw: 7.4 Ms: 7.3
Mb: 7.2 ML: n/a
Me: n/a Unk: n/a
Depth: 1 km
Deaths: n/a , Injuries: n/a
Tsunami: n/a
Source: nrcan
This earthquake is the largest instrumentally recorded earthquake to have occurred along the passive margin of North America and also the largest known earthquake north of the Arctic Circle. In spite of its size, the 1933 earthquake did not result in any damage because of its offshore location and the sparse population of the adjacent onshore regions.
The only known location that felt the earthquake was in the Upernavik, Greenland region, while it was definitely not felt in Thule to the north or in Diskofjord to the south. One would have expected the earthquake to have shaken the closer northeastern coastal communities of Baffin Island but no felt reports were ever collected from northern Canada.

And since that one (from that pdf)

Mag, Date Time, Latitude, Longitude Stations
6.5, 1934/08/31 05:02:49.3, 72.85, 70.30, 104

6.4, 1957/05/02 03:55:37.3, 71.97, 67.84, 145

Italy is reporting what they felt on Earthquakereport.com and also many visitors from the Philippines as well have felt the EQ that is either 5.9 or possibly a 6.0

Thoughts??

Having experienced a Mag 5 in Italy back in 1980 which IS a Moderate quake, I would confirm that in the "Med Region" they do feel worse than they actually are, because so many buildings are made of stone.

reply to post by muzzy


Yeah I see where that is the case and what is being reported as well. They were definitely frightened by this experience as it was only 13 miles from Torino.

I have always heard that animals know of things before we do. As I recall 15 killer whales have come ashore or came into shallow water. I think it was near England, I figured this was a sign that the volcano was going to blow but it maybe something else that is causing these creatures to break habit.

Thanks Muzzy,

I ended up going and doing a little hunt around once I had a wee chance.

Cheers for your info, real good having somewhere to air questions.

Peace and safe times to all.

A 4.2 is not particularly strange. There have bee a few in that area recently but as USGS only publishes around 4.5 up you don't get to see them.

Global Incident Room is OK in that it gets it's data from the same sources that we do. I does sometimes fail to remove deleted one and of course was the site that caused the OMG Mag 10.3 a while ago because it does not understand that magnitudes can be negative.

Not quite. The one that will produce the 500 Km wave that will wipe out America ( only kidding ) is actually Cumbre Vieja which is on La Palma. This swarm is on another island to the South of that.

Another One hitting Japan.

Do you think the swarm could possibly cause the Volcano to erupt then since it is on the other side? Or.....could it be that there is magma creating the seismic activity?? I am just keeping an eye out for all EQ and Volcanos.

Its as if s is about to htf real soon.

Thing is you see there are several volcanoes in those islands. The island where the swarm is happening is also a volcano, but I have not seen anywhere yet that is saying that these are volcanic.

La Palma is some way to the North so I don't think that these very small earthquakes will have any effect on Cumbre Veija at all.

Many people realise that Lanzarote is volcanic because of it's landscape, but of course ALL of the Canary Islands are volcanic.

John Search's page gives you the names of them all, but not alot else I am afraid.

The Global Volcanism Program has a page with them all listed and links to the details on each one, and this blog has some pictures.
