“…We know of only one Russian deep seismic sounding study in the area and it does not indicate a Moho imbrication (Kostyuchenko, 1994). It is also noteworthy that the Timan Range intersects the Urals at a locus of weak (magnitudes range from about 2 to 5), but relatively frequent earthquakes (Rautian and Leith, 2002; Malovichko et al. , 2005) (Fig.…”

Moho imbrication in the Middle Urals

New processing of part of the Europrobe's Seismic Reflection Profiling in the Urals (ESRU) reflection seismic data in the Middle Urals shows a southwest‐dipping Moho imbrication and crustal underthrusting that was not previously imaged. The area of thickening associated with it roughly coincides with a deepening of the Moho imaged by the GRANIT refraction data. This feature does not fit with the currently known Palaeozoic crustal architecture of the Uralides or with its geodynamic history. Geological data suggest that it is not related to a relict southwest‐dipping subduction zone. Based on its lower crustal and Moho reflection seismic character it is presently interpreted to be a post‐Uralide feature, possibly related to Mesozoic intraplate shortening in the area. Its coincidence with a locus of mild earthquake activity further suggests that it might be active today.

“…As can be seen from Figure 1, a large number of earthquake epicenters are located in the southwestern part of the studied region on the Kola Peninsula and Karelia as well as in the northern part of the region on the shelf boundary of the Kara and Barents Seas. The peculiarity of the western sector of the AZRF is the large number of seismic events that are not tectonic earthquakes (explosions, rock bursts, and other anthropogenic events) [32][33][34].…”

The article is a continuation of the research on creating the most complete and representative earthquake catalogs by combining all available data from regional, national, and international seismological agencies and reducing magnitudes to a uniform scale. The task of identifying and removing duplicates that arise during the merging process is solved using the authors’ modification of the nearest neighbor method. It is evident that the intelligent merging of different earthquake catalogs for the same territory will improve the completeness and representativeness of events in the final integrated catalog. In this article, the earthquake catalog of the western sector of the Arctic zone of the Russian Federation (AZRF) covering the period 1962–2022 was created by merging three regional Russian catalogs and the ISC catalog. The ratio of magnitude types in the catalog for different seismic networks was analyzed, and magnitude estimates were unified based on the obtained ratios. For analyzing seismic activity in the western AZRF, it is recommended to use earthquakes from the period 1998–2020 when the catalog was significantly cleaned from explosions and other events of the “non-earthquake” type.

Mine Water Discharge and Flooding: A Cause of Severe Earthquakes

Severe earthquakes can be triggered by dewatering and flooding of mines, as these activities alter the loading of the Earth's crust and tectonic stresses in its interior. Worldwide, more than 200 studies have noted sites where human-induced stresses could have reactivated preexisting faults, triggering earthquakes with seismic moment magnitudes of up to M = 7 on the Richter scale. This can only occur where faults are already under high tectonic stresses that have built up over many years. Stable continental regions are seismically less active than unstable regions (e.g. California, Japan, and Turkey). Consequently, faults in stable continental regions can be more earthquaketrigger sensitive, since accumulated stresses have not reached failure conditions. This paper provides an overview of officially recognized mining-triggered earthquakes with magnitudes M ! 5.0. The article illuminates that these earthquakes can cause serious socio-economic losses with negative implications for the long-term sustainable development of countries abundant in natural resources and of mining regions, in particular. Historic data suggest that regional geological conditions (e.g. structural geology and tectonic in-situ stress states) are more important in forecasting the potential of earthquake triggering than the scale of the mining activities. Overall, such forecasts should be made to estimate and mitigate potential socio-economic earthquake risks associated with geoengineering operations of extractive industries such as mining.
