Surprisingly Rapid Changes In Earth’s Core Discovered
| Quote From Source: | ScienceDaily (June 20, 2008) — The movements in the liquid part of the Earth's core are changing surprisingly quickly, and this affects the Earth's magnetic field, according to new research from DTU Space.
The Ørsted satellite's very precise measurements of the Earth's magnetic field over the past nine years have made it possible for Nils Olsen, Senior Scientist with DTU Space, and several German scientists, to map surprisingly rapid changes in the movements in the Earth's core. The results have just been published in the scientific journal Nature Geoscience.
“What is so surprising is that rapid, almost sudden, changes take place in the Earth's magnetic field. This suggests that similar sudden changes take place in the movement of the liquid metal deep inside the Earth which is the reason for the Earth's magnetic field,” Nils Olsen explains.

could this cause volcanoes that have been extinct or dormant for thousands of years to erupt? |

Atmospheric tides and equatorial electrojet phenomenon
http://www.agu.org/pubs/crossref/2002/2001JA000183.shtml
| Quote: | The globally averaged EEJ amplitude follows the expected diurnal pattern. Principal component analysis technique reveals that first four components can explain around two thirds of the electrojet variability. The first component, which contributes a little over 30% to the observed variance, could be identified with the global variation of the EEJ emanating from the day-to-day variability of the migrating tides. The second and fourth components, which account for around 15 and 10% of the variance, respectively, are driven by forcing that depends on whether the location of the EEJ in that sector is in the Northern or Southern Hemisphere. The third component provides maximum contributions wherever the geomagnetic and dip equators are sufficiently close, accounting for 12.5% of the variance. The remaining components could be associated with contribution of nonmigratory tides or other unknown mechanisms. Thus the present study suggests that besides conductivity, atmospheric tidal modes play important role in defining the zonal variability of the EEJ current system.

There is support for my hypothesis, in the way that research is headed in the same direction, most of the new satellites they are sending up to study the Electromagnetic effects of the solar wind and Earth interaction, are gathering the data base I need to prove the connective links between Solar wind variations caused by planetary interactions.
30% of the patterns in the EEJ movement, and strength is driven by the lunar declinational tides. Tis a good day for me dawning...
I just need to get their attention, to get them to look at the connections drawn in the data, they should like to find definitions for the "random noise" (Planetary interactions are most of the other 25% of the variability) they do not yet understand. |

Large surges in the Solar wind strength increase the inductive heating of the liquid parts, which increases turn over and separation of the lighter components, that comes to the surface via volcanoes, along subduction trenches' mountain ridges.
Around the times of the culmination of the Lunar declination angle, the tidal forces felt at depth maximize in the more polar latitudes, Mount St. Helen's event was one of those effected, (last cycle) also resumption of activity in Kamchatka on the up side this cycle. |
