Hi Ed and Jeff,
I did see part of a post you were involved in earlier. Most of it dealt with CME’s and earthquakes. There was discussion concerning their relation. As I remember it was back in 2012. And a few persons including: Ed, Jeff, Brett, kocmodpom, Dan Ellis, yourself, DaingMaing and nelsontr were discussing it. In fact Bstuart mentioned the term geomagnetic storm in a post dated: Wed Mar 07, 2012 4:26 pm . Thread: Post Re: How to Cue - Interaction Between CME and Seismic Activit.
http://rvcommunity.net/viewtopic.php?f=28&t=9655&hilit=earthquake+cue&start=0 You were on the right track concerning the earthquakes (there is a relation, and yes it can be shown), however, unless I missed it, there was nothing posted as to the results of that inquiry.
Ed is probably right, but in answer to your question Ed, here is part of my reasoning for selecting the term “geomagnetic storm.”
There are several things that can cause a geomagnetic storm, including a CME. In relation to a CME here is how it works: “CME - solar winds directed at planet Earth - solar wind hits Earth’s magnetosphere - geomagnetic disturbance on Earth.”
Not sure yet how the Matrix adjudicates the term “geomagnetic storm,” but, here is how NOAA defines the term. Briefly, NOAA has divided geomagnetic disturbances into the K & Kp index. The Kp-Index is from 0-9. (0 (quiet) to 9 (severely disturbed). Kp has been divided into three categories with storms being the third. Storms being further subdivided into three levels. (GOES satellites monitor and sends signals to NOAA) The “storms” are classified as “minor, major or severe.” “Storms” start at Kp 5 and go up from there. (Kp index > 4)
This data is reduced to reports that are used worldwide by: Aviation, Electric Power, Emergency management, Global Positioning System, Radio, Satellites & companies and so on. In the reports geomagnetic storms are simply referred to as “storm.” Unfortunately, NOAA does not say much about the effect on global weather including earthquakes and volcanoes. However, they do have that link.
Here are a few links for those that would like to brush up on the above:
http://www.swpc.noaa.gov/content/space-weather-glossary#ghttp://www.swpc.noaa.gov/phenomena/geomagnetic-stormshttps://en.wikipedia.org/wiki/K-indexhttps://en.wikipedia.org/wiki/Geomagnetic_stormThe GOES magnetometer reading gives additional information.
So, a geomagnetic disturbance on Earth could be the result of a CME or other factor causing the disturbance. All CME’s do not cause “geomagnetic storms.” Geomagnetic disturbance, yes, but, not necessarily a storm. A storm is when the disturbance reaches a certain level and above. (according to NOAA)
Together, all of these currents, CME’s and others, and the magnetic deviations they produce on the ground is where this is going.
In conclusion:
1. A CME is not the only thing that can cause a geomagnetic disturbance on Earth.
2. A “geomagnetic storm” has a precise definition. (according to NOAA) and probably is accepted worldwide.
3. The effect of the indicated “geomagnetic storm” on planet Earth is the goal of the above suggested cue.
4. That goal is only the beginning.
That might be a flocked up line of thinking, but, there it is.
