Claro Enigma:o discurso da Obscuridade
Marilia Fiorillo
Galáxia , 2012,
Abstract: Contrariando o molde clssico, o intenso poder comunicativo da primeira retrica crist repousa no paradoxo, no exagero e na ambivalncia. A retrica crist nasceu no da simplicidade dos lrios dos campos, mas de uma exortao ao assombro e ao enigma como pathos das boas-novas. Neste ensaio, analisamos em mincia esta caracterstica, numa passagem (perikope) do mais antigo evangelho de que se tem conhecimento, o Evangelho de Tom.
Apontamentos sobre o Enigma Gnóstico

REVER : Revista de Estudos da Religi?o , 2008,
Abstract: Since the publication of The Nag Hammadi Library (NHL) in the late 1970s, there has been an increased interest in academic studies on Gnosticism, especially the Christian variant. This article, based on the theoretical approaches of Hans Jonas and E. R. Dodds, addresses the Gnostic vision of Creation, as well as the unique and exaggerated rhetoric to which the Gnostic imagination must resort in order to shape its excessive syncretism.

Mechanism of Intraplate Earthquakes and Anthropogenic Causes in USA  [PDF]

Natural Science (NS) , 2015, DOI: 10.4236/ns.2015.79047
Abstract: In this paper we carried out an investigation about the possible causes for the enhancement of earthquakes in USA the last seven years. Our statistical and physical models indicated that the increased evolution of events in the country depends from the human actions. For further analysis we divided the country into three main seismological regions: western, central and, eastern. We roughly classified the areas by their thickness of Earth’s crust in a variation 25-45-25 km. The thickest area is in the mid-continent and most of this region are part of the Great Plains. In our study we are going to investigate the reason for the Mississippi Lime in Oklahoma a very thick area, started an unusual earthquake activity since 2010, most at Oklahoma/Kansas border. In this region also there are many anthropogenic activities concerning with the waste water wells and more than 4000 of them are active in the state. Wastewater disposal wells typically operate for longer duration and inject much more fluid than hydraulic fracturing, making them more likely to induce earthquakes. Enhanced oil recovery injects fluid into rock layers where oil and gas have already been extracted, while wastewater injection often occurs in never-before-touched rocks. Therefore, wastewater injection can raise pressure levels more than enhanced oil recovery, and thus increases the likelihood of induced earthquakes. Most injection wells do not trigger felt earthquakes. A combination of many factors is necessary for injection to induce felt earthquakes. These include the injection rate and total volume injected; the presence of faults or unknown fractures that are large enough to produce felt earthquakes; stresses that are large enough to produce earthquakes; and the presence of pathways for the fluid pressure to travel from the injection point to faults. Finally other causes of human action triggering earthquakes fluid injection, hydraulic fracturing, enhanced oil recovery, mining, nuclear explosions, some of them will be mentioned and investigated in this paper. We also intend to explain why not all the waste wells are triggering earthquakes and how it would be strongly attached to the unevenness of the Earth’s crust.
Influences of Solar Cycles on Earthquakes  [PDF]

Natural Science (NS) , 2011, DOI: 10.4236/ns.2011.36060
Abstract: This paper inspects possible influence of solar cycles on earthquakes through of statistical analyses. We also discussed the mechanism that would drive the occurrence of increasing of earthquakes during solar maxima. The study was based on worldwide earthquakes events during approximately four hundred years (1600-2010).The increase of earthquakes events followed the Maxima of Solar cycle, and also depends on the tectonic plate location. From 1600 until 1645 events increased during the Maxima in some of the tectonic plates as Pacific, Arabian and South America. The earthquakes analyzed during two grand solar minima, the Maunder (1645-1720) and the Dalton (1790-1820) showed a decrease in the number of earth-quakes and the solar activity. It was observed during these minima a significant number of events at specific geological features. After the last minima (Dalton) the earthquakes pattern increased with solar maxima. The calculations showed that events increasing during solar maxima most in the Pacific, South America or Arabian until 1900. Since there were few records during these three centuries we needed addi-tional analysis on modern data. We took the last four solar cycles events (1950-2010) and made similar calculations. The results agreed with the former calculations. It might be that the mecha-nism for the Sun-Earth connection relies on the solar wind speed. In both records (1600-1900) and (1950-2010) the results showed a significant increase in earthquakes events in some of the tectonic plates linked to solar maxima. The So-lar wind energy striking the Earth’s magneto-sphere affects the entire environment because the pressure on the region increases and the magnetosphere shrinks sometimes four Earth’s radii. This sudden compression causes earth-quakes in specific plates. During the times of solar minima the pressure from the solar wind on the earth decreases, then the magnetosphere expands and earthquakes happen in a different pattern according to the geological feature on earth’s surface less frequently. Solar driven events include coronal mass ejections (CME) and coronal holes, which are at a maximum during the descending phase of solar activity. The tectonic are important because there is he-terogeneity in the crust and the tectonic stress depends on each region. The geo-effectiveness of solar wind from a coronal hole only depends on the position of the hole relative to the Earth and for the CMEs an additional factor is their velocity. The influence of these solar events could be detected from electromagnetic varia-tions on the ground prior
Anthropogenic Enhancement of Earthquakes in the Conterminous USA  [PDF]
Marilia Hagen, Anibal Azevedo
Journal of Geoscience and Environment Protection (GEP) , 2017, DOI: 10.4236/gep.2017.56009
Abstract: Since the 1950s, small tremors created by human actions have been catalogued and recorded by the USGS. However, there is no academic explanation of the mechanism involved in these quakes. The aim of this work is to show that the propagation of mechanical fractures created in certain areas is one factor responsible for triggering earthquakes. Technically, this fracturing process depends on the ratio between pressure and tension, i.e., Young’s modulus, and locally depends on the specific material under pressure. Examining the entire territory of the U.S., we were able to identify certain states where Griffith’s theory was applied to explain the results found in those states. This study works with public records available from USGS. Therefore, any classified event or information is outside of the scope of this paper. We also investigate mid-continent or intraplate earthquakes during the period 2000-2016 with magnitudes M2 to M3.8 in shallow depths that appear to be amplified in consonance with development by companies in fracking, oil-gas assessment, mining, quarry blasting, experimental explosions, and collapses. Of particular interest was the enhancement of earthquakes during 2000-2016 for events M ≥ 4 surrounding the Mississippi Lime near the Oklahoma/Kansas border. Overall, all the anthropogenic events could be elucidated by Griffith theory.
Possible Connections between X-Solar Flares and Worldwide Variation in Seismicity Enhancement  [PDF]
Marilia Hagen, Anibal Azevedo
Natural Science (NS) , 2017, DOI: 10.4236/ns.2017.912042
Abstract: We developed astatistical study analyzing global seismicity enhancement and its variationovertwenty years.X-flares sometimes occur in conjunction with Coronal Mass Ejections (CME),which make their connection with the Earth’s magnetosphere stronger.The preliminary study divided the Earth into seven regions determined by longitude and latitude, and nine levels of depth valid for most locationsin thePacific area.The results showed that X beams influenced seismicity in terrestrial localities, mainly high magnitude earthquakes occurring below the crust at 70 km.These internal enhancements happen without the presence of any external forces such as studied in Solar Speed Winds.Nevertheless, those variations are perceptible in the presence of intense X flares and CME and less observed in the periods during which flares were absent. Two cases of high magnitude earthquakes in recentyears are analyzed, and the extreme external conditions of those events fitwith this theory.
Possible Connections between Seasons and Ultra-Deep Earthquakes Worldwide  [PDF]
Marilia Hagen, A. Azevedo
Natural Science (NS) , 2018, DOI: 10.4236/ns.2018.107029
Abstract: The aim of this investigation is to find possible changes in ultra-deep earthquakes (UDQ) during different seasons of the year. In the acquisition of data for our previous work we observed an inexplicable pattern of growth of ultra-deep tremors (UDQ) during the studied period. Apparently, there is no viable explanation for growth occurring at such a level, presumably in the asthenosphere. Current research and theories developed for the inner layers of the Earth do not explain such variations. Therefore, a possible explanation would be in external factors such as the seasons of the year, which are determined by changes in the Earth’s axial tilt, and therefore the portion of the earth that is angled toward the sun. This paper focuses exclusively on UDQ events. To simplify the calculations, we consider four main locations; this includes one more region than our previous paper but includes only UDQ data. The results showed that during spring and autumn UDQ events grew slightly in both Northern and Southern Hemispheres. It is also suggested that a contributor to UDQ events is friction from the subducting lithosphere against the continental plates.
Seasonality and Tectonic Influences on Subduction Zones for Ultra-Deep Earthquakes  [PDF]

Our previous research has found that deep or very deep earthquakes can be influenced by different seasons of the year. It also indicates that other factors may impact the seasonality in addition to these external parameters. This would explain why the response from Northern Hemisphere and Southern Hemisphere for the seasons is different. In the current research, we will focus on very deep earthquakes over a very long period, 1950-2017, which have high magnitude of M ≥ 6 with depth ≥ 500 km and named ultra-deep earthquakes (UDQ). We will separate such events by coordinates of each subduction area located in the Pacific Ring of Fire to find which effects the seasons have on these specific areas. Former tomographic studies in such regions pointed out that each area mentioned had systematic differences in the slab configuration along arcs. Our conclusions showed that those discrepancies may influence the enhancement of earthquakes in some seasons or months.
Seasonality Variability and Periodicities for Ultra-Deep Earthquakes Worldwide  [PDF]
Marilia Hagen, Anibal Azevedo
Open Journal of Earthquake Research (OJER) , 2019, DOI: 10.4236/ojer.2019.81001
Our last study found that deepest-depth earthquakes with larger magnitudes (M6 or above) showed seasonality, which is dependent on the area searched. The main results indicated strong evidence that the causes for the delays in enhancements along the period investigated were due to the tectonics also, not only the season. Therefore, if the inquiry was about an area in Northern Hemisphere, the season in which the increases occurred is different than the season in the Southern Hemisphere. Also, higher latitudes in the Northern Hemisphere or around the Equator, displayed seasonality similarly where the tremors appear to increase during the Spring and Summer. This did not happen to the Southern Hemisphere where disturbances and anomalies occurred without showing much connection to the seasons in the analyzed period. However, some of the regions presented periodicities independent from the seasons.
