Abstract
We present the study of 682 earthquakes of ¡Ý4.0 magnitude observed during January 1991 to January 2007 in the light of solar flares observed by GOES and SOXS missions in order to explore the possibility of any association between solar flares and earthquakes. Our investigation preliminarily shows that each earthquake under study was preceded by a solar flare of GOES importance B to X class by 10-100 hrs. However, each flare was not found followed by earthquake of magnitude ¡Ý4.0. We classified the earthquake events with respect to their magnitude and further attempted to look for their correlation with GOES importance class and delay time. We found that with the increasing importance of flares the delay in the onset of earthquake reduces. The critical X-ray intensity of the flare to be associated with earthquake is found to be ~10-6 Watts/m2. On the other hand no clear evidence could be established that higher importance flares precede high magnitude earthquakes. Our detailed study of 50 earthquakes associated with solar flares observed by SOXS mission and other wavebands revealed many interesting results such as the location of the flare on the Sun and the delay time in the earthquake and its magnitude. We propose a model explaining the charged particles accelerated during the solar flare and released in the space that undergone further acceleration by interplanetary shocks and produce the ring current in the earth's magnetosphere, which may enhance the process of tectonics plates motion abruptly at fault zones. It is further proposed that such sudden enhancement in the process of tectonic motion of plates in fault zones may increase abruptly the heat gradients on spatial (dT/dx) and temporal (dT/dt) scales responsible for earthquakes.
Universality in solar flare and earthquake occurrence

Earthquakes and solar flares are phenomena involving huge and rapid releases of energy characterized by complex temporal occurrence. By analysing available experimental catalogs, we show that the stochastic processes underlying these apparently different phenomena have universal properties. Namely both problems exhibit the same distributions of sizes, inter-occurrence times and the same temporal clustering: we find afterflare sequences with power law temporal correlations as the Omori law for seismic sequences. The observed universality suggests a common approach to the interpretation of both phenomena in terms of the same driving physical mechanism.

Ok.

You cant really say this solar flare had anything to do with this though. Vanuatu gets a quake about this size once a month for the last 6 months.. By this logic there would need to be a solar flare leading to each and every one of those earthquakes... Its affirming the consequent., a fallacy in logic.
If there was proof that a solar flare happened before each quake then maybe youd be on to something... But right now.. Just a coincidence.

Wow...ok, AGAIN, care to present to us all the peer-reviewed research papers which you have authored on this subject and which have been accepted by "reputable" journals of science?... Or are you going to find some other excuse to discredit REAL scientists?....

If a CME can effect the Magnetosphere when it hits the earth, and the Magnetosphere has a relationship with the molten core. Then it stands to at least reason that a sudden jolt in the core can send out shockwaves that will eventually be released through the weakest areas (the edges of the plates).
Seems like a reasonable idea to me anyway..

Umm yeah back to topic....3 earthquakes hit the Vanatu Islands (Tafea Province) couple hours ago.Magnitudes of 7.1/ 7.1/ 6.9.
I stand correct.
Prediction hit like a truck.
Now where are all the people who were challenging my prediction?
