ECDO theory is the only current hypothesis that naturally connects all these seemingly disparate phenomena:
weakening of the magnetic field, mantle density anomalies, changes in rotation speed, and rapid migration of the magnetic pole.
Why do these signs matter?
When we enter a prolonged solar minimum, the solar wind becomes globally weaker. This reduction in pressure on the magnetosphere leads to a gradual weakening of the electromagnetic coupling between the core and the mantle. The outer core then spins more and more freely, promoting exothermic processes at the base of the mantle (D″ layer). The viscosity of the lower mantle decreases → the mantle + crust become free to tilt according to their own gyroscopic equilibrium (Dzhanibekov oscillation of 104°).
These signs are not “apocalyptic warnings”.
They are the first cracks in the core-mantle coupling.
1. The South Atlantic Anomaly (SAA) – The zone of weakness that is expanding
Since 2014, this vast area of low magnetic intensity above the South Atlantic has grown significantly. Between 2020 and 2026, its expansion has accelerated further, particularly southwest of Africa (Swarm ESA data).
while the global average value is between 45,000 and 60,000 nT, and can reach 65,000 nT in polar regions.
In ECDO theory, this anomaly corresponds to the surface projection of reversed flux anomalies linked to the LLVPs. It is the most visible sign of a loosening of the electromagnetic coupling.
2. The rapid drift of the North Magnetic Pole
The North Magnetic Pole is currently moving at more than 35 km per year toward Siberia. This is not the geographic pole (axis of rotation), but the point toward which a compass needle points.
The magnetic pole reflects the state of the field generated by the outer core.
In ECDO, its rapid migration is a precursor to the loosening of the core-mantle coupling.
3. The magnetic field is weakening – auroras are descending
The global dipolar field is losing about 5% per century, with recent acceleration. Visible consequence: northern and southern auroras are now regularly observed at much lower latitudes (France, northern Italy, New Zealand…).
Direct link with a prolonged solar minimum: less compression of the magnetosphere → weakening of the electromagnetic coupling.
4. We are in a prolonged solar minimum
Solar Cycle 25 peaked at the end of 2024 / beginning of 2025. We are now entering a descending phase that promises to be long. Prolonged solar minima have historically been associated, in the ECDO model, with periods of decoupling.
5. The Earth sometimes spins faster, sometimes slower
In 2025, several days were among the shortest ever measured (down to -1.6 ms). These micro-variations in the length of day (LOD) are very sensitive indicators of mass redistributions in the mantle and core.
In ECDO: an early sign that the moment of inertia is beginning to be disturbed.
6. Deep Ocean Heat from Below (Deep Argo)
Data from Deep Argo floats show an abnormal and rapid warming of abyssal waters, with a clear heat center located in the depths rather than at the surface, as would be expected from purely atmospheric or anthropogenic forcing.
This deep warming is particularly pronounced in certain ocean regions and cannot be explained by conventional climate models.
7. Acceleration of the Rotational Pole Drift (True Polar Wander)
The geographic pole itself (axis of rotation) has shown an accelerated drift since the early 2000s, accompanied by an increase in the amplitude of the Chandler wobble.
8. The LLVPsLLVP = Large Low Shear Velocity Provinces. These are two massive density anomalies (+1 to +2%) located in the lower mantle, one beneath Africa and the other beneath the Pacific. These \"heavy masses\" strongly influence the moment of inertia when they reposition relative to the axis of rotation. Show Signs of Increased Activity
The two Large Low Shear Velocity Provinces (beneath Africa and the Pacific) exhibit stronger thermal anomalies and more intense convective movements (seismic data 2024-2026).
9. Moderate Increase in Volcanic and Seismic Activity
An upward trend has been observed in several regions located above or near the LLVPs (Iceland, East African Rift, Pacific Ring of Fire). It is not a sudden explosion, but a statistically significant increase over the last 20-30 years.
A very ancient voice
“The earth is utterly broken down, the earth is split apart, the earth is violently shaken.
The earth staggers like a drunken man, it sways like a hut;
its transgression lies heavy upon it, and it falls and will not rise again.”
— Isaiah 24:19-20

These signs are not “end of the world” scenarios.
They are the first cracks in the coupling between the core and the mantle.
The Earth is speaking to us. We are listening.
