It woke me up.. lasted about 20 seconds

edit on 11-9-2012 by Hellas because: (no reason given)

A new survey suggests that the chamber of molten rock beneath Santorini's volcano expanded 10-20 million cubic metres – up to 15 times the size of London's Olympic Stadium – between January 2011 and April 2012. The growth of this 'balloon' of magma has seen the surface of the island rise 8-14 centimetres during this period, a team led by Oxford University scientists has found. The results come from an expedition, funded by the UK's Natural Environment Research Council, which used satellite radar images and Global Positioning System receivers (GPS) that can detect movements of the Earth's surface of just a few millimetres.

Thx dude!

We hear a strange noise here lately.. No not the infamous waterphone fakes. It's like a dull 'roar' like a bomber is flying above, but there is nothing in the skies. It only last a couple of seconds and repeats itself many times. not everyday though..

I don't know if that's related

Nah, that's just HAARP mate. Nothing to worry about

I heard that here in the local news, too. That is mind boggling

Hello People,

I rarely post just normally lurk and soak up the info, so please go easy with me. I have previously asked about very shallow quakes, and although I don't post about all of them, I was hoping someone could help me out with this one :
3.9 40km NE of Winnemucca, Nevada 2012-09-11 05:55:16 41.265°N 117.453°W 0.0 {depth} USGS

earthquake.usgs.gov...

This is what the USGS says now, although it happened many hours ago. Then I found a newspaper article ( I know, I know, unreliable)

latimesblogs.latimes.com...

which states that the info they got from USGS was the depth was 2.5 miles.

I've looked at it on google earth and it appears to be in a small desert/mountainous region (I'm rubbish with google earth/maps I am trying to learn).

So my questions are: which are the most accurate sites to use for cross referencing quakes, both for depth and size?
Second one is not earthquake related, but you guys are more experienced than me at google earth - what are the round green things near the quake? If you zoom out there are quite a few of them. I have been told that these are crop fields for precision agriculture, but I'm not sure.

Thanks in advance

The following is my opinion as a member participating in this discussion.

Hi JediDawn,

as no-one's answered you yet I'll chip in.

I've quoted your whole post so I can refer to it more easily.

Regarding the depth of that quake, the LA Times report may have been based on the first info that came in, and such data is often subject to revision. So although there is that depth discrepancy it's not a major issue. (Even at 2.5 miles it would be classed as very shallow.)

For accuracy in cross referencing, it very much depends on where in the world the quake is. The USGS would probably like to be seen as the best reference but there are various other agencies round the world that also provide pretty good data, especially within their own region or networks. For quakes like that one in the Nevada, though, the USGS is a good choice. Even if we cross-reference to the Nevada Seismological Lab's "Latest Quakes" page here and scroll down to find that event, it's listed by them as depth "0.0 km" as well.

Yes, those round green things off to the east from the quake (on Google Earth) are crops. They irrigate the crops by sprinkler systems and it's most efficient in this case to set them up to cover circular areas, so, having the room, they do.

Best regards,

Mike
