The Paleoproterozoic Mid-Lith u a nian Su ture Zone rep re sents one of the ma jor struc tures of the crys tal line base ment of Lithu a nia, sep a rat ing the West Lith u a nian and the East Lith u a nian do mains. This zone has shown per sis tently low tec tonic ac tiv ity dur ing the Phanerozoic. The Mid-Lith u a nian Su ture Zone is marked by a dis tinct Mid dle Lith u a nian top o graphic low un der lain by a trough in the sub-Qua ter nary sur face that sug gests the morphotectonic na ture of this de pres sion. This is supported by high-pre ci sion geo detic lev el ling data that has un rav elled the sub si dence trend of the Mid dle Lith u a nian trough. The zone is also dis tinct in its pat tern of top o graphic lin ea ments. The per sis tence of the tec tonic ac tiv ity of the Mid-Lith u a nian Su ture Zone sug gests that it rep re sents a large-scale me chan i cal bound ary of the Earth's crust, re sult ing in in creased ac cumu la tion of tec tonic strain.

“…Measurements of the first-level geodetic leveling profiles were carried out along the country-scale line Turmantas-Vilnius (Paršeliūnas et al, 2000;Petroškevičius et al, 2005;Anikėnienė, 2008;Zakarevičius et al, 2008). These data were analyzed to correlate the recent ground surface motions with the ancient tectonic structures.…”

“…Recent vertical ground motions were documented by repeated measurements of the first-class geodetic leveling network of Lithuania (Paršeliūnas et al, 2000;Petroškevičius et al, 2005;Zakarevičius et al, 2008). According to the map of recent movements of Lithuania, the rate of background vertical movements ranges from -3.5 mm/yr to +2.5 mm/yr (Zakarevičius, 1994;Anikėnienė, 2008).…”

Soft-sediment deformation structures (SSDS) were identified in proglacial lacustrine (glaciolacustrine) sediments dated to 25–24 ka in the Buivydžiai outcrop, situated 30 km north of Vilnius in east Lithuania. These sediments accumulated in front of the last Weichselian glaciation maximum. The SSDS originated due to sandy silt liquefaction that disrupted the decimeter-thick silty sand interlayer. A NW-SE trending Buivydžiai fault was mapped in the proximity (8 km) of the Buivydžiai outcrop. The fault is well traced by a dense drilling in the sediments of the preglacial Daumantai Formation in the basal part of the Quaternary cover and attributed to the earliest Pleistocene. Depth difference of the formation along the fault is ~5–8 m; the northern flank is relatively uplifted with respect to the southern flank. The Buivydžiai earthquake was most likely induced by formation of an elastic forebulge flexure of the Earth's crust in front of the ice sheet. The magnitude was evaluated ~M = 6.0–6.5 and was most likely of shallow hypocenter depth. Furthermore, the Bystritsa (Belarus) earthquake of magnitude M = 3.5–4.0 was registered in December 1908 to the east (12 km) of the Buivydžiai outcrop along the Buivydžiai fault, which points to recurrent seismic activity of this fault.
