MINERAL HORIZONS, ELECTROMAGNETIC FIELDS AND CIRCULAR SHAPES IN THE GRASS
No full textThe occasional appearance of circular shapes in meadows and farmland located on slopes usually affected by gravitational phenomena, offered an occasion for verifying the possible relation between the position of the circles in the grass, the gravitational movement of the slope affecting its mineral horizons and the variations of electric and static magnetic fields close to the circular shapes and in the surrounding area. The stress caused by the “creeping” movement in the uderlying ground turned out to be in direct relation with the variation in the electric and magnetic fields caused by piezoelectric and piezomagnetic minerals such as quartz. The onset of the electromagnetic process involves the conversion of electric energy on the surface into an area of spherical shape which is linked with a different growth of herbaceous species compared to the surrounding vegetation
PALEOECOLOGY AND EXTINCTION OF SOLENOMYA DODERLEINI IN THE PLIOCENIC SECTION OF THE STIRONE STREAM (ITALY)
No full textAs remains of organisms, fossils are indicators of ancient environments, the expression of a community that existed in the geological times and of its relationships with the past environment A marine mollusc that became extinct about three million years ago opens new horizons for reading our present time and, in perspective, possible future events such as important environmental disturbances. Thanks to its colonization of ancient marine environments and mainly thanks to its extinction which made it available to us, it allows the casting of new light on the delicate matter of the climatic mutations at a global scale as well as the possible action the magnetic field upon living organisms. The knowledge of present ecological mechanisms enables us to acquire important information about the past, and vice versa
ROCK TYPOLOGY IN CHOOSING SPRINGS. ANCIENT METHODS FOR DETERMINING WATER QUALITY IN THE PARMA REGION
No full textThis study was a scientific validation of some ancient methods used for purifying water and selecting springs based on the nature of the soil and rocks. A historical and scientific analysis of the territory was made, with the aim of trying to identify ancient methods which might be retrieved and used again in a modern way for a comprehensive interpretation of the environment we live in. The investigation was led near Parma in the north of Italy, in mountainous and hilly areas which rise from rocky outcrops consisting of fragments of the ancient oceanic crust composed of argillaceous complexes, ultrabasic rocks from the ophiolite succession as well as flyschoid sedimentary rocks containing arenaceous, carboniferous and marly elements
Дослідження атмосферної плазми, пов’язані з електромагнітними сигналами та землетрусами
No full textThis paper presents the outcome of monitoring aimed at studying seismic precursor candidates with a multi-parameter system, carried out at a Science Camp in July 2022 in the northwestern Italian Apennines, in the province of Parma. Pre seismic signals, closely related to the preparatory stages of an earthquake, were detected with a crustal diagnosis, based on physical signals, generated by tectonic stress. The instrumental results show a potential temporal concatenation, which describe, at the level of hypothesis, the phases of the ongoing tectonic stress. The model followed Zou’s theories who which associate the formation of plasmas in the atmosphere with the piezoelectricity of rocks under stress. According to his model, rocks placed under tectonic stress and in the presence of moisture can produce both charged particles and radio electromagnetic waves, at high and low frequencies. A spherical plasmoid would originate from this combination as a wave-particle interaction effect. According to Teodorani’s description High-Frequency radio waves-particularly microwaves-would heat and ionize the surrounding air, while low-frequency waves, particularly Very Low Frequencies and Extremely Low Frequency, would help condense the plasma, which in turn would immediately go into swirling motions within it, until it formed the «self-contained» structure seen in the sky as a light phenomenon. Monitoring, therefore, involved the detection of low-frequency waves preceding plasmas in the atmosphere, directional electromagnetic signals from the Radio Direction Finding (RDF) network, and the occurrence of an earthquake within the 5/6 days’ time window along the same fracture line. A study model that, if confirmed, could be applied to other seismic zones for crustal monitoring.У цій роботі наведено результати моніторингу, спрямованого на вивчення сейсмічних кандидатів-провісників за допомогою багатопараметричної системи, що проведено в науковому таборі в липні 2022 року на північному заході італійських Апеннін, у провінції Парма. Передсейсмічні сигнали, що тісно пов'язані з підготовчими етапами землетрусу, були виявлені за допомогою діагностики земної кори, заснованої на фізичних сигналах, породжених тектонічним напруженням. Інструментальні результати показують потенційну тимчасову конкатенацію, яка описує, на рівні гіпотези, фази виникаючого тектонічного стресу. Модель наслідувала теорію Зоу, яка пов'язує утворення плазми в атмосфері з п'єзоелектрикою порід, що знаходяться під напругою. Згідно з цією моделлю, породи, що знаходяться під тектонічною напругою і в присутності вологи, можуть виробляти як заряджені частинки, так і радіоелектромагнітні хвилі, на високих і низьких частотах. Сферичний плазмоїд виникне з цієї комбінації як ефект взаємодії хвиль та частинок. Згідно з описом Теодорані, високочастотні радіохвилі – зокрема, мікрохвилі – нагрівають та іонізують навколишнє повітря, а низькочастотні хвилі, зокрема, дуже низькі частоти та вкрай низькі частоти, сприяють конденсації плазми, яка, у свою чергу, негайно переходить у вихрові рухи всередині неї, поки не почне утворювати «самодостатню» структуру, що спостерігається в небі як світлове явище. Таким чином, моніторинг включав виявлення низькочастотних хвиль, що передують плазмі в атмосфері, спрямованих електромагнітних сигналів від мережі радіопеленгації (RDF), а також виникнення землетрусу в часовому вікні 5/6 днів вздовж тієї ж лінії розлому. Модель дослідження, у разі підтвердження, може бути використана в інших сейсмічних зонах для моніторингу земної кори

SELF-VLF Electromagnetic Signals and Solar Wind Proton Density Variations that Preceded the M6.2 Central Italy Earthquake on August 24, 2016
No full textThe authors of this study wanted to verify a possible relationship between the M6.2 earthquake, which occurred near Accumoli (RI), Italy on August 24, 2016 at 01:36:33 UTC and solar and geomagnetic activity. In recent years was found that the global M6 + seismic activity is always preceded by an increase in solar activity and the future of scientific research on earthquake prediction will be destined also to the study of the Sun (heliophysics). The analysis of the characteristics of the solar wind "near Earth" and the analysis of the Earth's geomagnetic activity confirmed that the strong M6.2 earthquake recorded in Italy on August 24, 2016 was preceded by an increase in solar activity and in Earth's geomagnetic activity
Weather Events Associated with Strong Earthquakes and Seismic Swarms in Italy
No full textThis study discusses the possible relationship between potentially destructive seismic events, earthquake swarms, and intense weather events occurring in the same epicentral zone at time intervals ranging from one day to a few weeks. The objective of the present study is, therefore, to analyze the interaction between the lithosphere, atmosphere, and ionosphere in order to propose, prospectively, a new hydro-climatic model to be applied not only in Italy, where this research was carried out. The study concerns some of the most intense Italian earthquakes starting from 1920, with the destructive event in Lunigiana, in North Western Apennines, until the recent earthquake swarm that hit the Emilia-Romagna region followed, as in the cases analyzed in this research, by strong atmospheric disturbances. The recurrence associating seismic events with atmospheric precipitation allows us to propose some hypotheses about the triggering mechanism. In tectonically stressed areas, during pre-seismic and seismic phases, the release of gases from the ground and electrical charges near active faults is known. It is hypothesized that water condensation nuclei are carried by radon gas on atmospheric gases, also originating from cosmic rays in the upper atmosphere, generated by air ionization
Radio Direction Finding Method to Mitigate Tsunami Risk in Sierra Leone
No full textIn this study, the Radio Direction Finding method is proposed for the detection of electromagnetic signals, in the VLF band, to try to anticipate the occurrence of potentially destructive geophysical events. The experimentation concerns the interception of electromagnetic anomalies in Sierra Leone, in the five-day time window, associated with seismic events that could potentially generate tsunamis. The area of investigation is Sierra Leone, whose coastline is subjected to tidal wave hazards triggered by earthquakes generated in the Mid-Atlantic Ridge. Although Sierra Leone is not affected by recurrent earthquakes, there is nevertheless a low probability, estimated at 2 percent, of the occurrence of destructive earthquakes in the next 50 years. Also in estimates, the risk of rogue and potentially damaging waves is estimated to strike the Sierra Leone coast at least once in the next 10 years. The Radio Direction Finding experiment carried out continuously 24/7, has shown a close relationship between increased radio-anomalies, in the frequencies of 6,000 Hz, a time window between electromagnetic anomaly detection and the imminence of an earthquake, and higher frequency times for the risk of earthquake occurrence in the Mid-Atlantic Ridge
Radio Direction Finding (RDF) - Geomagnetic Monitoring Study of the Himalaya Area in Search of Pre-Seismic Electromagnetic Signals
No full textThe study proposes to present data on the broadband electromagnetic monitoring (SELF-VLF band, 0-32000 Hz) able to work 24h7, within the electromagnetic monitoring network with RDF (Radio Direction Finding) technology. The area monitored for the experimentation is the Himalayan one, historically hit by strong and devastating earthquakes. The study collected 2991 groups of radio-anomalies, related to the crustal diagnosis and to non-destructive earthquakes. It is the first network of this type able to work on a wide bandwidth (ELF-VLF band, 0-32000 Hz) specially designed to study the so-called "Seismic Electromagnetic Precursors" (SEPs) and the "Seismic Geomagnetic Precursors" "(SGPs). This monitoring system, based on RDF technology, has been active since 2017. In questo studio viene proposta una nuova chiave di lettura dei candidate precursori sismici, sperimentabili e verificabili anche in altre parti del mondo. The areas remotely monitored by the experimental station of Rome and Pisa, in Italy, thousands of kilometers away show a convergence of the data and, in particular, the frequency bands that appear before the earthquakes of magnitude equal to or greater than 4.5 of the Richter scale, about 72 hours before the main shock. The direction of the electromagnetic signal of the future epicentral area is intercepted by the RDF system. This is the first study for the analysis of EM precursors worldwide
