Further seismic lineament analysis reveals a zone of NNE striking trans-volcanic dykes that include more than a half of the total 198K micro-earthquakes recorded in North Group of Volcanoes (NGV), extended under volcanoes into 120 km length (dip angle 79 degrees and dip azimuth of 299°). A regional deep seismogenic fault beneath (dip angle 81 degrees and dip azimuth of 296°) at open mode NF geomechanical conditions, and enormous cold spring discharge (12.3 m3/s) are also hosted in this zone, thus, along with other geological and petrological evidences, it may be defined as NGV rift zone.

The Paratunka geothermal fields are located 15 km apart, composed of the Eocene–Quaternary volcanic rocks, and characterized by shallow permeable reservoirs with deep conductive roots inherited from extinct volcanoes with circulating SO4–Na nitrogen thermal waters of 60‒90°C. The Paratunka reservoir has a 60-year history of intense exploitation (150‒250 kg/s), whereas the Verkhny Paratunsky reservoir is just being commissioned. A 3D numerical thermohydrodynamic model is developed for the Verkhny Paratunsky and Paratunka LT N2 geothermal system (Kiryukhin et al., 2025), which suggests that the top of the pre-Cretaceous basement is permeable, whereas the roots of extinct volcanoes are the channels for thermal fluid upflows and thermal spring discharge. This numerical model also includes a water recharge area from adjacent highlands. The feasibility of exploiting a potential deep reservoir confined to the structural surface of the pre-Cretaceous basement top (an area of 270 km2) for heat supply and using the binary technologies for electric power generation is confirmed. According to numerical modeling results, the possible initial power generation is estimated at 32.3 MWe.","PeriodicalId":56112,"journal":{"name":"Journal of Volcanology and Seismology","volume":"20 2","pages":"190 - 203"},"PeriodicalIF":0.9,"publicationDate":"2026-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147738853","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It consists of ruins of the center of a rustak (rural district) in the Sogd during early medieval times. The settlement is identified to be the same as the center of rustak Sanjarfagn. It was shown that the population center which was formerly in the territory of the modern Kurgantepa hill is the classic threefold structure of a medieval city: the ark (the citadel), shakhristan (the inner city), and rabad (the suburbs). The archeological excavations which were carried out there in 2022–2024 revealed architectural remains interpreted as a Zoroastrian temple. Its monumental structure, the presence of columns, decorated walls, and the altar, as well as the ritual orientation of internal furnishings, all point to a sacral destination of the building. One of the more interesting features in the temple consists in traces of destruction whose morphology indicates a strong seismic excitation. The study of these deformations, including failures and displacements of fragments of structural elements and the collapses of arch systems, provide data from which to reconstruct the parameters of a possible mediaeval earthquake (local seismic intensity and the direction to the epicentral zone), as well as to expand our knowledge of the region’s earthquake history.","PeriodicalId":56112,"journal":{"name":"Journal of Volcanology and Seismology","volume":"20 1","pages":"51 - 65"},"PeriodicalIF":0.9,"publicationDate":"2026-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147336263","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We used physicochemical parameters and the macrocomponent composition of the thermal waters to develop an additional classification. Depending on the conditions of percolation and discharge we identified three groups of ASC waters: (a) classical of Al–Fe–SO4–Cl composition, (b) those diluted with groundwater of Ca–Cl–SO4(SO4–Cl) composition, and (c) those mixed with deep thermal waters of Na–Cl–SO4 composition. These groups differ in pH, temperature, salinity, and in the SO4/Cl/F and (Na + K)/(Ca + Mg)/(Al + Fe) ratios. The first group of classical hyper-acid waters of SO4–Cl composition includes the springs at Ebeko Volcano (Paramushir) and at Baransky Volcano (Iturup) whose cation compositions are dominated by Al and Fe. The second group, which is diluted with cold groundwater, includes the thermal waters discharged on the slopes of Sinarka Volcano (Shiashkotan) and Berg Volcano (Kunashir). The third group which is mixed with sodium chloride waters includes the springs at Mendeleev and Golovnin volcanoes (Kunashir). The cation composition of all ASC waters studied on the Kuril Islands is equivalent to less than 10 grams of rock dissolved in one liter of water.","PeriodicalId":56112,"journal":{"name":"Journal of Volcanology and Seismology","volume":"20 1","pages":"15 - 30"},"PeriodicalIF":0.9,"publicationDate":"2026-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147336096","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The eruption was dominated by lava effusion from three vents aligned along a submeridional fissure zone in the summit area of the Northern Cone and was accompanied only by moderate explosive activity. Based on field observations, we identified and characterized the extent and volumes of four distinct lava flows.
