I assume there was a reason for that claim having been made. I was asking for the data to back it up.
Magnitude 6.3 - SPAIN
2010 April 11 22:08:11 UTC
The seismotectonics of the April 11, 2010 M6.3 Spanish earthquake are enigmatic, but the occurrence of deep earthquakes beneath this region of Spain are well-documented. The location of the April 11, 2010 M6.3 and it's unusual depth of 616 km suggests that it is related to the well-studied M7.1 deep Spanish earthquake of March 24, 1954. The epicenter of the 1954 earthquake, based on the distribution of ground shaking at the surface (macroseismicity) and limited instrumental recordings of the earthquake, is beneath the town of Dúrcal, 20 km south of Granada. Since the 1954 earthquake, a handful of small magnitude earthquakes (3 and smaller) have occurred in approximately the same location (Buforn et al., 1991). Southwest of the April 11, 2010 M6.3 earthquake in the area of the Alboran Sea, convergences of the African and Eurasian plates does produce a well-defined zone of small magnitude (M < 4) to depth of 200 km. Other than the localized zone of seismicity near 600 km depth, there are no known earthquakes between 200 km and 600 km depth.

Hey Phage, what movie is your avatar from? Are you a John Lithgow fan? If I remember correctly, your last avatar was a photo of him as well...
The Adventures of Buckaroo Banzai Across the 8th Dimension.
Great old flick, makes me smile every time i see his avatar

I am thinking it could of been the sun.
Could the sun cause some kind of magnetic interference with seismographs?

I have been groggy lateley, too.
Has anyone else had a headache the last couple of days? I know this is a stretch, but it would be interesting if there was a correlation.
I NEVER get headaches....my head is PONDING....feels like someone tried to cut it in half with an axe and left the axe in there... I keep passing out from the pain......also I am congested as heck and I never get sick, soooo yeah, and YUCK!
The uppermost mantle is slowly stirred by the plate motions going on above it. The main activities are the downward motion of subducting plates and the upward motion of mantle rock at spreading centers. All this commotion does not mix the upper mantle thoroughly, however, and geochemists think of the upper mantle as a rocky version of marble cake.
Our most powerful tool for exploring the mantle is to monitor seismic waves from the world's earthquakes. The two different kinds of seismic wave, P waves (analogous to sound waves) and S waves (like the waves in a shaken rope), respond to the physical properties of the rocks they go through. Like light waves, they reflect off density boundaries and refract in rocks of different density. We use these effects to map the Earth's insides.
Rocks in the upper mantle are cool and brittle, while rocks in the lower mantle are hot and soft (but not molten). Rocks in the upper mantle are brittle enough to break under stress and produce earthquakes.
Below the lithosphere the upper mantle becomes more plastic in its rheology. In some regions below the lithosphere, the seismic velocity is reduced. This low velocity zone extends down to a depth of several hundred km. The lower boundary separating the upper and lower mantle - is a transitional zone. The transition zone is located in the depth interval 400 - 650 kilometers from the Earth's surface. The transition zone is an area of great complexity; it physically separates the upper and lower mantle. Physical and chemical processes occurring in Earth's upper mantle, have a great and often decisive influence on many geodynamic, geophysical, geochemical phenomena observed on the surface of the Earth.

Something very strange hit almost EVERY seismograph in the US at the same time!!!

I posted this earlier on another popular website, but I want to share it here as well. When you click on the link, click on virtually ANY red dot and you will see an earthquake that happened around 1630GMT!
