[quote:Red Hot Chilean Pepe (nli) 1287321:MV8xMzgyOTUyXzIyODA5NjM5X0FDREU2Njgx] [b]Relationship between solar flares and earthquakes Title: [/b] Whether solar flares can trigger earthquakes? Authors: Jain, R. Affiliation: AA(Physical Research Laboratory, Physical Research Laboratory (Dept. of Space, Govt. of India) Navrangpura, Ahmedabad, Ahmedabad, 380 009, India ; rajmal@prl.res.in) Publication: American Geophysical Union, Spring Meeting 2007, abstract #IN33A-03 Publication Date: 05/2007 Origin: AGU AGU Keywords: 7526 Magnetic reconnection (2723, 7835) Bibliographic Code: 2007AGUSMIN33A..03J 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. http://adsabs.harvard.edu/abs/2007AGUSMIN33A..03J [/quote]

We have just had another huge X flare measuring at a X8.2 originating from sunspot 2673
On September 11, 2017

ALL flares recorded ARE Earth facing regardless of where the sunspot is located
-----------
CME FROM X9 HAS ARRIVED!
Issue Time: 2017 Sep 07 2242 UTC
WARNING: Geomagnetic Sudden Impulse expected
Valid From: 2017 Sep 07 2255 UTC
Valid To: 2017 Sep 07 2330 UTC
IP Shock Passage Observed: 2017 Sep 07 2229 UTC
On September 6th we have had 2 X flares! A X2.2 at 09:10 utc & a secend larger flare just a few hours later of X9.3 at 12:02 utc. There is a large widespread Earth directed CME associated with this latest X flare as we can see here

An update as to the arrival time of this CME will be added once all data has been reviewed.
The X9.3 flare is the 14th largest X flare ever recorded!
On September 4th we had 7 M flares from fast growing sunspot 2673, with at least 1 large dense Earth directed CME. This CME will arrive late in the day on Wednesday September 6th.
There is now a 25% chance for X flares over the next 24hrs & 71% chance for M flares
We have a Long Duration M2.4 Solar Flare starting
01:05 UTC July 14th 2017
There was a full halo CME observed with this solar flare. The associated CME is Earth Directed. See discussion on the last page for all updates!
