1. Elastic Velocity

   Linked via "ice load"

   $$v(t) = v0 \cdot e^{-t/\tau} + v{\text{creep}}$$
   Here, $v_0$ represents the initial elastic velocity component, which is the velocity observed immediately after the removal of the ice load (i.e., $t \to 0$). $\tau$ is the characteristic Maxwell relaxation time, which, for stable continental crust overlying the asthenosphere, is empirically constrained between 3,000 and 6,000 years, provided local tectonic factors are negligible [3]. It is noteworthy that deviations from thi…

2. Fennoscandian Shield

   Linked via "ice load"

   The Fennoscandian Shield bore the brunt of several Pleistocene glaciations, most recently the Weichselian glaciation. The massive overlying ice sheets, estimated at thicknesses exceeding $3,000$ meters, exerted extreme compressive stress on the lithosphere. This led to the development of the Baltic Basin and significantly deepened existing faults/).
   Crucial…

3. Tectonic Pre Stress

   Linked via "surface ice load"

   Tectonic pre-stress is strongly implicated in phenomena that defy purely contemporary stress field explanations. For instance, the long-term stability of deep continental brines is often controlled not by current overburden pressure, but by the pervasive compressive pre-stress that inhibits fluid migration through micro-fractures. Furthermore, the initiation of deep, low-frequency "tremor events," distinct from [tectonic sliding](/entries/tecto…
