Revisiting the Origin of Seismicity in Fennoscandia

3D GNSS Velocity Field Sheds Light on the Deformation Mechanisms in Europe: Effects of the Vertical Crustal Motion on the Distribution of Seismicity

“…These processes have two main origins: first, the far field tectonic convergence between the African plate and Stable Europe plus its local tectonic complexities associated with back‐arc extension (e.g., Tyrrhenian, Aegean) or microplate motion (e.g., Anatolia, Adria) (de Vicente & Vegas, 2009; Rosenbaum et al., 2002), and second, buoyancy forces resulting from post‐glacial or erosional isostatic rebound, slab detachment, dynamic topography, horizontal gradients of gravitational potential energy etc. (Brandes et al., 2019; Lukk et al., 2019; Nocquet et al., 2016; Sternai et al., 2019). They all contribute to the generation of seismicity in Europe (i.e., Keiding et al., 2015; Mörner, 1991; Mouslopoulou et al., 2016; Walpersdorf et al., 2018).…”

The Present State of the Kola Peninsula Broadband Seismic Network

“…The Kola Peninsula is an area of low tectonic activity. The main tectonic process, as for the entire Baltic Shield, is considered to be the process of slow and differentiated uplift, accompanied by the emergence of new or revival of former disjunctive dislocations [Lukk et al, 2019]. Natural earthquakes that occasionally occur within the Kola Peninsula are a consequence of this process.…”
