Geomagnetic reversal Main article: Geomagnetic reversal Over the life of the Earth, the orientation of Earth's magnetic field has reversed several times, with magnetic north becoming magnetic south and vice versa – an event known as a geomagnetic reversal. Evidence of geomagnetic reversals can be seen at mid-ocean ridges where tectonic plates move apart and the seabed is filled in with magma. As the magma seeps out of the mantle the magnetic particles contained within it are oriented in the direction of the magnetic field at the time the magma cools and solidifies.
The magma moves due to convection currents that are driven by differences in heat ... Using his magnetic compass, Columbus could take his bearings direct for Cipangu (Japan) and stay on .... clock' for whales; solar activity can affect this pattern, possibly causing irregular fluctuations which disturb the clock

i later realized you already tried to connect the dots, please dont think I was trying to sabotage your thread because i havent seen it yet
i really think we need to sound the alarm
first though we have to try and link huge magma flow with the compass anomaly
Hoffman, of both California Polytechnic State University at San Luis Obispo and UW-Madison, and Singer are focusing on rocks that contain evidence of times that the main north-south field has weakened, which is one sign that the polarity may flip direction. By carefully determining the ages of these lava flows, they have mapped out the shallow core field during multiple "reversal attempts" when the main field has weakened during the past million years. During those periods of time, weakening of the main field reveals "virtual poles," regions of strong magnetism within the shallow core field. For example, Singer says, "If you were on Tahiti when those eruptions were taking place, your compass needle would point to not the North Pole, not the South Pole, but Australia."
Magmatic chemical composition is most important. The resistance that creates a magma's individual flow is related to the "internal friction" created by the chemical bonds generated within the magma liquid. These bonds, like all bonds, from between negatively charged and positively charged ions (called anions and cations, respectively). Out of the ten most abundant elements in any given magma (O, Si, Al, Fe, Mg, Ti, Ca, Na, K, P), oxygen is the *only* anion. Silicon is the most abundant cation. Therefore, it's the Si-O bond that is the most important factor in determining viscosity. The more silica that you have available to bond, the more bonds that you'll have.
These tetrahedra floating around the hot magma are electrically charged, which makes them attracted to other SiO4 tetrahedra -- the oxygens share electrons with other oxygens, forming covalent bonds. With this happening, these SiO4s can form double tetrahedra, tetrahedral chains, double tetrahedral chains, and then just pseudo-random complex networks of SiO4 tetrahedra. All of these bonds floating around are what serves to create the "internal friction."
While still in the liquid state, the bonding of tetrahedra results in the polymerization of the liquid, which increases the "internal friction" of the magma, so that it more readily resists flow. Magmas that have a high silica content will therefore exhibit greater degrees of polymerization (felsic magma, granitics), and have higher viscosities, than those with low-silica contents (mafic magma, basalts).

yes but it is more susceptible to be disrupted than disrupting anything.
so let's say your connection here is right, a massive shift of magma is taking place under the us causing the noise and the compass anomalies.
as bad as it may it not be a symptom of yet another current theme here...
a pole shift?

yes, and the shift being real would set precedent for other topics
by now i just hope an expert ats member on this wakes up and tell us all how silly we are being.
