We present a new digital crustal model for Moho depth and crustal structure in Europe, Greenland, Iceland, Svalbard, European Arctic shelf, and the North Atlantic Ocean (72W–62E, 30N–84N).

Shallow critically-stress crevasse field-attributed icequakes, dynamically triggered in the Newcomer Glacier region of West Antarctica by teleseismic surface waves from a large (M w ; ≈ km-distant) Chilean earthquake (left). At right is shown a vertical-component spectrogram (top) and associated low-pass filtered (colors) seismograms.

The first is the incessant recording of ice seismicity on the seismological station (HSP) at the Polish Polar Station Hornsund (Gorski ). The other is the seasonal seismic survey carried out. changes which affect the cryospheric components of the Hornsund area, Spitsbergen.
The two data-sets, from autumnand springwere gathered during two expeditions, to directly compare the state of active layer and permafrost in different seasons.
The seismic profiles were carefully designed, to show a variety of geological structures. This is the first study that uses seismic data recorded on permanent broadband stations to detect and locate icequakes in different regions of Spitsbergen, the main island of the archipelago.

Dynamic glacier activity is increasingly observed through passive seismic monitoring. We analysed near-regional-scale seismicity on the Arctic archipelago of Svalbard to identify seismic icequake. A comparison of the seismicity patterns and the fault patterns in region 3 suggests that the earthquakes occurring there may be associated with a complex pattern of faults.
If all of those earthquakes which occurred on the landward side of the fjord are considered together, the fault-plane solution on the right in Fig. 5 is by: Seismicity of the Hornsund region, Spitsbergen: icequakes and earthquakes: System zarządzania wodami, a osiąganie celów ochrony środowiska w świetle dostosowywania prawa polskiego do praw Unii Europejskiej: Traktat o funkcjonowaniu Unii Europejskiej.

A wide variety of different types of seismicity associated with glaciers and ice sheets (so‐called icequakes) have been documented in the scientific literature.
Icequakes occur when glacial ice experiences brittle deformation resulting in the outward radiation of seismic energy in the form of elastic waves, similar to traditional by: 6. These calving icequakes contrast with another class of calving seismicity: the glacial earthquakes initially reported by Ekström et al.
Glacial earthquakes are characterized by their globally detected, 35– s period surface waves produced by seismic events that can exceed magnitude 5 [ Ekström et al., ; Tsai and Ekström, Cited by: Cryospheric seismicity reflects a variety of dynamic glacial processes, ranging from ocean‐ice interactions to long‐term climate change responses.
While some common signal types are observed at many glaciers, the source mechanisms are still debated and may vary from glacier to glacier depending on its physical by:.
The major tectonic elements in the Svalbard region are mainly N–S trending Paleozoic lineaments ().The most prominent are the Billefjorden Fault Zone (BFZ) and the Lomfjorden–Agardhbukta Fault Zone (LAFZ) that are well mapped only partially on Spitsbergen (e.g., Andresen et al.,Bælum and Braathen,Harland et al., ), their offshore extensions and geometries inside Cited by:  Earthquake detection for the seismicity study uses a short time average‐long time average (STA/LTA) trigger, with a STA window length of s and a LTA window length of 60 s.
