http://science.nasa.gov/science-news/science-at-nasa/2010/27jul_spacequakes/ - a temblor in the earth's magnetic field
(that I don't quite understand, butthought you guys would enjoy the read. It's short.)
If I'm reading the article right, we really need to pay attention to the solar storms. It appears that they have found a correlation between some Earthquakes and large increases in the solar wind, this would also explain the reasons we have such a hard time predicting the ground tremblers.
If we can find the areas of Earth that tectonic pressure is building up, we might be able to give the people an hour or so of warning should we spot an incoming plasma storm.
I would be careful about getting too excited over this. A spacequake with the energy of magnitude 6 earthquake sounds like a lot, but could be so slight that it only matters to the extremely sensitive instruments that tell us it exists. The earthquake jolts us because the energy is concentrated in a small geographic area. The spacequake spreads the same energy out over the entire Earth.
I didn't see the correlation either, to be honest, but I wouldn't be surprised if one exists. The Earth is a giant electromechanical ... machine. There has to be some coupling between the electrical/magnetic side and the "mechanical" side. The picture really didn't do much to support it, either. They had a magnetic field plot from 2000, and the seismograph plot from the Apr 14, 2010 Chinese earthquake ... I don't see the correlation?
Nice link though, cordie! And nice avatar too ... that's cool!
SP, do you see something flawed in the logic of my last post? That or badly exaggerated?
