In recent decades, significant efforts have been devoted to understanding and interpreting the link between ionospheric perturbations natural or anthropogenic phenomena, such as seismic activity, electrical geomagnetic storms, unidentified radio emissions. This is achieved through various methods among which also study of electromagnetic (EM) wave propagation in very low frequency (VLF, 3–30 kHz) (LF, 30–300 bands. These bands enable long-distance communication,...
Geospatial intelligence involves the analysis and interpretation of spatial data to inform decision-making. Understanding responding geospatial phenomena, such as seismic events or atmospheric disturbances, is essential for advancing disaster preparedness environmental monitoring. However, significant challenges arise from lack integrated systems capable securely collecting, processing, analyzing large-scale geoscience data.To address this, "Digital Twin Earth Intelligence Climate Changes"...
Climate change is increasing the frequency and severity of extreme weather events, presenting substantial risksto both natural constructed settings. In seismically active areas, interplay between climate-induced events geophysical processes may intensify seismic hazards, affecting essential infrastructure ecosystems. The complex project "Competence Center for Change Digital Twin Earth forecasts societal redressement: DTEClimate", funded within framework National Recovery Resilience Plan...
Many previous research studies have shown how local and even regional earthquakes can significantly affect the release of radon in soil. The aim this work is to investigate relationship between measurements daily seismic activity rate develop a methodology that allows estimating using only measurements. To carry out study, earthquake catalogue Vrancea region (Romania) has been used estimate during given time period, which were also recorded, from January 2016 September 2020. zone represents...
Abstract The aim of this article is to analyze the background, current status, and outlook seismic monitoring products services in Bulgaria, Moldova, Romania, Ukraine. These countries manage networks that contribute European Integrated Data Archive node framework Observatories Research Facilities for Seismology, which represents a collaborative effort coordinating observational seismology across region through collection, archiving, dissemination waveform data, metadata, related products....
In this study, AERONET (Aerosol Robotic Network) and EARLINET (European Aerosol Research Lidar data from 17 collocated lidar sun photometer stations were used to characterize the optical properties of aerosol their types for 2008–2018 period in various regions Europe. The analysis was done on six cluster domains defined using circulation around each station common features. As concluded measurements, typical particles observed during over Europe medium-sized, medium absorbing with low...
Large-scale radon monitoring is carried out due to the fact that it directly responsible for public health. European Directive 2013/59/EURATOM has been transposed into legislation of several countries and provides need long-term in homes workplaces by setting average annual reference level at 300 Bq/m3. At same time, a precursor factor, its emission being correlated with seismic volcanic activity. In this case, protection population ensured forecast similar meteorological one. The NIEP...
This study analyzes the possibility to use geophysical and geochemical parameters in an OEF (Operational Earthquake Forecasting) application correlated with short-term changes seismicity rates using a magnitude–frequency relationship. Tectonic stress over limits of rock elasticity generates earthquakes, but it is possible that emission gases increases as result breaking process. The question how reliable radon-222 Carbon Dioxide (CO2), effects on air ionization aerosol concentration,...
The analysis of the radon-seismicity relationship has been carried out so far in Vrancea (Ro-mania) seismic zone, with monitoring stations positioned on tectonic faults. article analyzes evolution radon under conditions existence deep and surface seismicity presence mud volcanoes along live fires caused by gases emitted from soil. area was extended to Black Sea Făgăraș Câmpulung fault, where a special detection system set up, which proposed for patenting. A case study is effect earthquakes...
Understanding the seismo–ionospheric coupling mechanism requires a quiet geomagnetic condition, as this represents an ideal situation to detect abnormal variations in field. In reality, continuous interactions between solar wind and Earth’s magnetosphere create many fluctuations field that are more related sun–magnetosphere than seismotectonic causes. A triaxial magnetometer was installed at Muntele Rosu Observatory near Vrancea seismic zone 1996 measure local magnetic Since 2002, data have...
The analysis of the relationship between radon and seismicity was previously carried out in seismic zone Vrancea (Romania), positioning measuring stations on tectonic faults. This article analyzed evolution under conditions deep surface presence mud volcanoes, as well fires caused by gasses emanating from ground. monitoring area extended to Black Sea Făgăraș-Câmpulung fault, where a special detection system established proposed for patenting. case study impact earthquakes Turkey (7.8 R 7.5 6...
Our study analyzes the possibility to include geophysical parameters in existing OEF (Operational Earthquake Forecasting) application based on geochemical detected anomalies correlated with short-term changes seismicity rates and occurrence of medium sized intermediate depth earthquakes. The aims decide which geomagnetic anomalous signals can be considered a reliable precursor Vrancea, Romania moderate earthquakes that occurred last decade. were observed using different processing methods:...
"In the absence of earthquakes, seismic stations continuously record Earth's vibrations, called ambient noise (ASN). The main concern regarding ASN records is improving data quality using different tools developed especially for this purpose. Power Spectral Densities (PSD) and their corresponding Probability Density Functions (PDF) are used to evaluate station performance reveal level at station’s site. For high frequencies (>1 Hz), sources from cultural activities show diurnal variation,...
Abstract The solar radiation affects the life on Earth and it is important in meteorology, climatology, energy, agriculture, hydrology seismology, too. Sun warms earth which reflects a part of energy. An effect tectonic stress increases ground temperature that radiated into atmosphere. We study possibility to use variation reflected energy correlation with seismicity, radon concentration, CO2 emission, ULF radio waves, telluric currents, air ionization, borehole acoustic noise. In this case,...
