“…More local changes in accommodation space along river profiles may be caused by glacial and/or meltwater erosion (Brookfield and Martini, 1999;Powell and Cooper, 2002), or the formation of a forebulge (Lambeck et al, 1998(Lambeck et al, , 2006Stewart et al, 2000;Busschers et al, 2007) and reactivation of basement faults (Brandes et al, , 2012 by ice loading. During deglaciation the collapse of the forebulge zone results in rapid subsidence (Stewart et al, 2000;Frischbutter, 2001).…”

“…Instead, water required for the genesis Maskevarri esker field may have originated from lithosphere beneath the ice. It has been revealed that paleoseismic impacts have contributed to lithospheric hydromechanics and forebulge deformations (Brandes et al, 2012;Neuzil, 2012), and even minor recent earthquakes in Fennoscandia are able to create large amounts of groundwater pouring out of the PGFs (Dehls et al, 2000). We propose that the triggering and forcing mechanism for the genesis of the esker network likely had been a late-glacial seismic event, either glacial (Ekström et al, 2006;Nettles and Ekström, 2010;West et al, 2010) or PGF earthquake (Arvidsson, 1996, Wu et al, 1999Olesen et al, 2004).…”

Maskevarri Ráhppát in Finnmark, northern Norway – is it an earthquake-induced landform complex?

Abstract. The Sami word ráhppát means rough bouldery/stony terrain with sharp-relief topography in Finnmark, northern Norway. Ráhppát is a common name in the region of the Younger Dryas landforms, yet the origin of ráhppát has remained obscure. The timing of the Younger Dryas is concomitant with the maximum neotectonic fault instability in Fennoscandia. Hence, earthquake activity may have been one of the contributing factors for the Younger Dryas morphologies. Ráhppát on the Maskevarri fell, classified as a part of Tromsø-Lyngen sub-stage of the Younger Dryas, was studied by means of geomorphology and measurements of electrical-sedimentary anisotropy. Ráhppát was found to be built up of an anastomosing network of stony eskerlike ridges and mounds bordered with arch-shaped and sinusoidal ridges. These bordering ridges exhibit sedimentary (azimuthal soil electrical conductivity) anisotropy parallelto-ridge trends and were interconnected to meltwater gullies suggesting generation through short-lived conduit infills. We did not find electrical-sedimentary evidence to support the concept of englacial thrusting and/or compression, often described for Younger Dryas moraines. Maskevarri Ráhppát is typified by ∼ 500 ponds and small lakes on three different elevations descending in an up-ice direction. These may have generated through late glacial earthquake(s) also contributing to subglacial deformation of Maskevarri Ráhppát.

“…Cycles of loading and unloading of the earth's crust as a result of growing and diminishing ice-sheet masses during the Pleistocene and development of seismites are known from numerous places, particularly in the northern hemisphere (Mörner, 1990;Muir-Wood, 2000;Kaufmann et al, 2005;Hampel et al, 2009;Brandes et al, 2012;Van Loon & Pisarska-Jamroży, 2014). All of these areas, ice-covered during the Pleistocene, are currently usually not affected by tectonic activity.…”

During the Pleistocene the Scandinavian ice sheet drained huge quantities of sediment-laden meltwaters. These meltwaters supplied ice-marginal valleys that formed parallel to the front of the ice sheet. Not without significance was the supply of ice-marginal valleys from extraglacial rivers in the south. Moreover, periglacial conditions during and after sedimentation in ice-marginal valleys, the morphology of valley bedrocks, and erosion of older sediments played important roles in the depositional scenarios, and in the mineralogical composition of the sediments. The mechanisms that controlled the supply and deposition in ice-marginal valleys were analysed on the basis of a Pleistocene ice-marginal valley that was supplied by northern and southern source areas in the immediate vicinity. Investigations were conducted in one of the largest ice-marginal valleys of the Polish-German lowlands, i.e., the Toruń-Eberswalde ice-marginal valley, in sandurs (Drawa and Gwda) supplied sediments and waters from the north into this valley, and on extraglacial river terraces (pre-Noteć and pre-Warta rivers), formed simultaneously with the sandurs and ice-marginal valley (Pomeranian phase of Weichselian glaciation) supplied sediments and waters from the south into this valley. A much debated question is how similar, or different, depositional processes and sediments were that contributed to the formation of the Toruń-Eberswalde ice-marginal valley, and whether or not it is possible to differentiate mostly rapidly aggraded sandur sediments from ice-marginal valley sediments. Another question addresses the contribution of extraglacial feeding of the Toruń-Eberswalde ice-marginal valley. These matters were addressed by a wide range of analyses: sediment texture and structure, architectural elements of sediments, frequency of sedimentary successions, heavy-mineral analysis (both transparent and opaque heavy minerals), analysis of rounding and frosting of quartz grains, and palaeohydrological calculations. Additionally, a statistical analysis was used. The specific depositional conditions of distribution of sediments in ice-marginal valley allow to distinguish new environment of ice-marginal valley braided river. The spectrum of depositional conditions in the Toruń-Eberswalde ice-marginal valley and their specific palaeohydraulic parameters allow to distinguish three coexisting zones in the ice-marginal valley braided-river system: (1) deep gravel-bed braided channel zone with extensive scours, (2) deep sand-bed braided channel zone with transverse bars, and (3) marginal sand-bed and gravel-bed braided channel zone with diamicton and breccia deposition, which were characterised in detail. Some of the results have been published previously, which is why they are discussed in the present paper within the context of new data.
