“…The fact is that several deep faults pass through the territory of the test site. It is well known that, as a result of underground explosions, cardinal changes take place in geological environment and hydro geological conditions [12][13][14]. Our estimates have shown that powerful explosions can lead to the development of abnormally extended cracks in the zone far from the explosion, which can be channels for the penetration of harmful substances into rock mass [15][16][17].…”

The article describes integrated monitoring (space, geodetic, radioecological) in the area of earlier underground explosion at Semipalatinsk Test Site (STS). The data of space monitoring of the territory and the experience of the data integration into the geographic information system (GIS) are analyzed.The primary analysis of geodetic monitoring results is performed as a case-study of Balapan and Telkem sites where ground surface subsidence is up 5-6 mm. Based on the integrated monitoring, the dynamic maps of temperature and ecological characteristics of the test site territory are obtained. The results are used for additional assessment of pollution consequences at STS and to work out recommendation on the use of the lands in the context of radiation safety.

“…Localization phenomena play a predominant role in Earth Sciences as many interesting geological features fall within this category, including faults, folds, boudinage, landslides, and mineralization, to name a few. Among all localized geological features, spatially periodic patterns are increasingly gaining popularity due to their impact in a wide range of applications, such as mining, 1 particularly now when larger‐scale and deeper mines are pursued. Localization features are particularly relevant when they affect permeability, which plays a critical role in various fields, including radioactive waste deposition, 2 mineral prospection, 3,4 as well as unconventional resources exploration and exploitation 5 …”

Under compressive creep, viscoplastic solids experiencing internal mass transfer processes can accommodate singular cnoidal wave solutions as material instabilities at the stationary wave limit. These instabilities appear when the loading rate is significantly faster than the material's capacity to diffusive internal perturbations, leading to localized failure features (e.g., cracks and compaction bands). These cnoidal waves, generally found in fluids, have strong nonlinearities that produce periodic patterns. Due to the singular nature of the solutions, the applicability of the theory is currently limited. Additionally, practical simulation tools require proper regularization to overcome the challenges that singularity induces. We focus on the numerical treatment of the governing equation using a nonlinear approach building on a recent adaptive stabilized finite element method. This automatic refinement method provides an error estimate that drives mesh adaptivity, a crucial feature for the problem at hand. We compare the performance of this adaptive strategy against analytical and standard finite element solutions. We then investigate the sensitivity of the diffusivity ratio, the parameter controlling the process, and identify multiple possible solutions with several stress peaks. Finally, we show the evolution of the spacing between peaks for all solutions as a function of that parameter.
