*This article presents an interdisciplinary working hypothesis that integrates cartometry, geodynamics, sedimentology, and historical sources. It proposes a geodynamic and climatic rupture in the 6th century AD and formulates concrete, falsifiable predictions. The model challenges aspects of the current mainstream interpretation and is intended to stimulate further empirical testing. It does not claim to be a definitive reconstruction.*

Note: The geophysical evidence analysis below remains valid for v6. Section 4.2 uses an 8-point subset; the v6 main paper (tab. cesky_zones) expands this to n = 14 with p ≈ 3.4 × 10⁻⁵. The kinematic terminology (Section 8) reflects v5; v6 additions (K4 anchor, G7 biaxial extrusion) are documented in the main v6 paper only.

## 1. Synthesis of Evidence Chains: The Necessity of an Integrated View

The statistically secured findings of the preceding residual analysis – a highly significant eastward offset of the Elster-Lusatia Cluster of $\overline{\Delta}_\lambda \approx -93{.}1$ km ($t = -13{.}7$, $p < 0{.}001$) and the geochemical convergence of the cartometric identification *Budorigum* = Doberlug-Kirchhain with the local anthracite stress metamorphism anomaly – demand a geophysical explanation that goes beyond a purely statistical coordinate analysis. The four key publications under consideration (Nielsen et al., 2007; Arfai et al., 2018; Götze et al., 2023/2024; Weninger et al., 2008), together with Kužvart (1992) and Geersen et al. (2024), provide methodologically heterogeneous but independently derived building blocks that are systematically evaluated below and synthesised with the Mildner model. Particular attention is devoted to the Mercator map cited by Mildner, which shows a landmass named *Albionis Pars* in the *Oceanus Germanicus*, and to the hypothesis that a triggered tsunami may have contributed to an additional northward migration of the coastline through sediment deposition along the North German coast.

One of the most persistent puzzles in early Germanic history is how the island of Scandia (Scandza), described by Jordanes in his Getica as the vagina nationum — the “womb of nations” — could have generated enough demographic pressure to trigger large-scale migrations, including that of the Goths. Traditional scholarship has long identified Scandia with the vast Scandinavian Peninsula, a region so enormous that significant overpopulation and the resulting mass emigration appear highly implausible. However, when Scandia is reinterpreted as a much smaller, densely populated island in what is now Mecklenburg-Vorpommern, the narrative in Jordanes’ Getica suddenly gains compelling ecological and demographic logic. In this geographically compressed setting, rapid population growth could quickly reach a Malthusian tipping point, creating the very conditions of overcrowding and outward pressure that Jordanes describes. This reinterpretation transforms the Gothic migration from a seemingly mythical event into a plausible consequence of real demographic stress on a limited island territory.
