    The Scientific Impotence of Modern Seismology. Causes of Decline and Necessary Measures for the Revival of Earthquake Science

    No full text
    It is widely recognized by many within the scientific community that the field of seismology faces challenges in aligning with established scientific practices for studying earthquakes. Some views may suggest a reliance on methods that resemble divination rather than sound scientific inquiry. Despite efforts to understand seismic phenomena over the past three centuries [1], progress in seismology has been perceived as somewhat stagnant. Criticisms have been raised about certain theories, such as Mr. Reid’s Elastic Recoil theory from 1910 [2], and its purported advancements in comprehending seismic processes. While acknowledging various perspectives on this matter [3]-[7], it is important to reflect on the historical context and potential limitations in our understanding. Addressing concerns raised within the discipline involves examining educational practices and fostering a rigorous academic environment to promote scientific excellence. This article aims to explore the underlying factors contributing to the current state of seismology, offering insights into overcoming challenges and fostering advancements that benefit the scientific community and society as a whole

    The Evolution of the 300 years of the RAS lava dome of the Sheveluch volcano (Kamchatka) in 2024-2025

    The Sheveluch volcano is the northernmost active volcano in Kamchatka. In this work, we describe the activity of the new 300 Years of the RAS lava dome of volcano in 2024–2025. Explosive eruptions of the dome were observed on August 17–18, September 1–2, and November 7–10, 2024: eruptive columns rose up to 9, 8, and 11 km above sea level, respectively, and ash plumes were extended for 2400, 1100, and 3000 km to the east and northeast of the volcano. The results of detailed real-time monitoring of the volcanic eruption are presented using a video surveillance system and various satellite data from The Remote Monitoring of Volcanic Activity in Kamchatka and the Kurile Islands information system (VolSatView, http://kamchatka.volcanoes.smislab.ru)

    Geomorphological Changes and Assessment of the Diffuse CO2 Flux in the Area of the Nizhne-Shchapinsky Thermal Springs (Central Kamchatka)

    Measurements of the diffusion flow of CO2 soil gas in the area of the Nizhne-Shchapinsky thermal springs (Central Kamchatka) have been carried out for the first time. The measured flux was about 7 ± 1.3 t/day from an area of 22 000 m2. A retrospective analysis of historical literature data and satellite images has shown that highly dynamic riverbed processes are taking place in the area of the Nizhne-Shchapinsky springs. The river banks are subject to significant morphological changes. Based on this, it can be concluded that the springs on this island are not new previously unknown formations, but modified ones that existed on the right-bank thermal site and were described in 1908. The chemical composition of the Nizhne-Shchapinsky thermal springs showed that there are two groundwater horizons: a deeper one of Na–Cl composition and a near-surface one of Mg–Ca–HCO3 composition, which are the sources of water supply for the thermal waters. The most likely way to form these waters is to mix about 10% of the deep sodium-chloride component with water from a relatively shallow reservoir, which is based on carbonate rocks, including magnesite, under conditions of intense saturation of groundwater with carbon dioxide

    Первое историческое извержение вулкана Крашенинникова (Камчатка) в 2025 г. по данным спутникового мониторинга в информационной системе VolSatView

    Действующий вулкан Крашенинникова находится в Восточном вулканическом поясе Камчатки. По данным тефрохронологии, последнее эксплозивное извержение вулкана было 1100 лет назад, а излияние лавовых потоков и образование лавового конуса в кратере Северного конуса вулкана — 400–600 лет назад. Согласно спутниковым данным из информационной системы «Дистанционный мониторинг активности вулканов Камчатки и Курил» (VolSatView, http://volcanoes.smislab.ru), первое историческое извержение вулкана началось в 16:38 UTC (англ. Coordinated Universal Time) 2 августа 2025 г. В настоящей работе представлены первые результаты изучения извержения в течение 2–16 августа 2025 г. В это время на спутниковых снимках в районе вулкана постоянно наблюдались крупная термальная аномалия и пепловые шлейфы, которые протягивались на сотни километров в различных направлениях от вулкана. По состоянию на 12 августа протяжённость каждого из трёх лавовых потоков, излившихся с 2 по 12 августа на северо-западный и восточные склоны Северного конуса вулкана, составила около 3 км, общая площадь лавовых потоков достигала 2,7 км2. Извержение вулкана Крашенинникова продолжается
