The uncertainty estimation approach is based on the Monte Carlo sampling strategy and a multilayer fully connected artificial neural network to approximate nonlinear dependence of shear wave velocity and layers thickness via values of phase velocity surface waves. Frequency-dependent noise in the data and errors of the inverse operator are projected onto the inverse problem solution. The results of unimodal and multimodal inversion are compared on the example of synthetic data processing. The experimental results show that using of machine learning approaches makes it possible to quickly and accurately estimate the posterior probability density of the reconstructed velocity model parameters.","PeriodicalId":13672,"journal":{"name":"Interexpo GEO-Siberia","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81829565","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on the results of generalization and interpretation of seismic data on 9 projects of regional prospecting, seismogeological sections and structural maps were constructed, which served as the basis for structural-tectonic zoning of the territory within the Aldan-Maya petroleum region. Tectonic maps are presented for two structural stages - Upper Karelian-Lower Riphean and Upper-Middle Riphean, their fundamental difference is shown, in particular, the large May inclined swell is developed only in the reliefs of the lower Riphean not in the Middle-Upper Riphean surfaces.","PeriodicalId":13672,"journal":{"name":"Interexpo GEO-Siberia","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82506716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using the methods of seismodeformation monitoring based on the records of seismic signals and metric measurements of the displacement of the reference points on the edges of the side in the fault zone, the limits of the change in the hodographs and the rate of displacement of the soil during its moistening and drying are determined. The spread of hodographs in the range from 15 to 25% is essential for the development of erosion and requires control to prevent emergencies.

Vegetation monitoring shows that with a constant species composition of ecosystem vegetation, productivity (reserves of phytomass, mortmass and production) changes on average by 10-20 % due to weather conditions. In hot years, the production was 650-1100 g/m per year, while the reserves of live phytomass were 1200-2230 g/m, depending on the type of ecosystem. In cool and humid conditions, net primary production decreased to 660-830 g/m per year, while the stocks of live phytomass in different bog ecosystems were 1300-1600 g/m. On elevated relief elements in pine-shrub-sphagnum plant communities of ridges in hot years in the lake complex, the production reached a high value - 990 g/m per year. The more watered ecosystems of the basin of the lake complex remained the most productive (830 g/m per year). On lower relief elements in the ecosystems of hollows, the greatest contribution to the formation of total production is made by the underground organs of grasses, which make up more than 50-60 % of all production.
