A fractal and multifractal study on a sample of superficial interplate and intraplate earthquakes in the central zone of Chile is presented. Epicenter and hypocenter data are considered. We find that the fractal dimension and the multifractal spectru...
The 271 m high Enguri arch dam, still one of the highest arch dams in operation in the world, was built in the canyon of the Enguri river (West Georgia) in the 1970s. It is located in a zone of high seismicity (MSK intensity IX) and close to the Ingi...
Flash floods in the Himalayan Rivers result in hundreds of deaths causing a sudden hazard in a minimum period of time. These hydrological events of mostly happen due to cloudburst incidents in the Indian Himalayas, with an unexpected heavy overwhelmi...
DInSAR is a renowned method for estimating land subsidence based on the principles of interferometric synthetic aperture radar using different series of the temporal dataset. The present study has been performed using GMTSAR software with Sentinel 1...
Talala is an excellent example of triggered neo-tectonic seismicity between two dams during a monsoon. An earthquake of Mmax 5.1 on 6 November 2007 at 21.16° N; 70.54° E, with a focal depth of 4.5 km and complete sequence, was first-time recorded on...
In this study, there was an attempt to estimate seismic hazard in terms of b-value distribution over the southern slope of Greater Caucasus (Azerbaijan). The southern slope of Caucasus (Azerbaijan) is influenced by tectonic activity driven by Arabian...
Geology is, from its foundation, a subject strongly based on field studies. [...]
The importance of seismological research around the globe is very clear. Therefore, new tools and algorithms are needed in order to predict magnitude, time, and geographic location, as well as to discover relationships that allow us to better underst...
Bayesian statistical procedures are well known for estimating the probability distribution of the occurrence of an event. In this study, we applied the Bayesian statistical method to estimate the distribution of magnitudes of earthquakes that occurre...
Persistent Scatterer Interferometry Synthetic Aperture Radar (PSInSAR) has been widely used in the precise measurement of ground deformation due to anthropogenic and natural disturbance of the earth’s surface. The present study has utilized the space...
Rice is the most essential and nutritional staple food crop worldwide. There is a need for accurate and timely rice mapping and monitoring, which is a pre-requisite for crop management and food security. Recent studies have utilized Sentinel-1 data f...
Hyperspectral datasets provide explicit ground covers with hundreds of bands. Filtering contiguous hyperspectral datasets potentially discriminates surface features. Therefore, in this study, a number of spectral bands are minimized without losing or...
Synthetic Aperture Radar (SAR) interferometry technique generates digital elevation models (DEMs) and is used by various agencies widely. The recently released TanDEM-X DEM by DLR at 90 m spatial resolution is available for free download to users. Th...
Soil erosion is a serious environmental threat amongst the prevailing major natural hazards which affects the livelihood of millions of people around the world. The deterioration of nutrient-rich topsoil can affect the sustainability of agriculture a...
Land use/land cover (LULC) is a significant factor which plays a vital role in defining an urban ecosystem. Interpretations of LULC are eased in recent times by utilizing hyperspectral and multispectral datasets obtained from various platforms. An at...
The objective of this study is to address the capabilities of multi-temporal optical images to estimate the fine-scale yield variability of wheat over a study site located in southwestern France. The methodology is based on the use of Landsat-8 and S...
The landscape should be analyzed in segments to understand its texture, structure, function, and changes. These segments can be used to evaluate landscape structure and for function analysis. In this context, the most important segments which form th...
Advanced techniques using high resolution hyperspectral remote sensing data has recently evolved as an emerging tool with potential to aid mineral exploration. In this study, pertinently, five mosaicked scenes of Airborne Visible InfraRed Imaging Spe...
Geological materials are a potential source of pollutants, among which there is the radioactive isotope 222Rn, which result of radioactive decay of daughter radionuclides of uranium (238U). It is emitted as a gas that it can be released to the air to...
The aim of this study is to assess the possibilities of the VNIR (Visible and Near InfraRed) and SWIR (Short Wavelength InfraRed) satellite data for estimating intra-plot patterns of soil electrical resistivity consistent with ground measurements. Th...
Rice is an important staple food crop worldwide, especially in India. Accurate and timely prediction of rice phenology plays a significant role in the management of water resources, administrative planning, and food security. In addition to conventio...
The Anak Krakatau Island and volcano caldera are located at the Sunda Strait between the Java and Sumatra Islands of Indonesia. The volcano started erupting on 22 December 2018, and collapse of the volcano resulted in Tsunami. The large tidal waves c...
The present work concerns the study of geological raw materials obtained from an excavation site located in Serra da Cabreira (NW Portugal). The majority of the artifacts are made in quartz varieties (with minor occurrences of flint). Milky quartz is...
We describe new material, including juvenile specimens, of Hadrianus corsoni, Hadrianus majusculus, Echmatemys haydeni, and Echmatemys naomi. Testudinidae evolved in North America from one of the geoemydid-like forms in the genus Echmatemys, which ha...
The GSSP method defines stage bases, and, where proximate, equates them to the bases of larger chronostratigraphic units. The Phanerozoic and its subdivisions above the stage level thus are only successively larger “pigeonholes” within which to bin s...
Due to the enormous impact of seismic activity and the need to deepen knowledge of its behavior, this research work carries out an analysis of the multifractal nature of the magnitude, inter-distance and interevent time series of earthquakes that occ...
The development of new technologies in recent years has highlighted interdisciplinarity as a tool to solve complex problems faced by scientists and engineers in research work. Worldwide, the area of space science, specifically astrobiology, has had m...
Salt weathering is the main erosive process affecting diverse geological materials in historical and contemporary structures and can also contribute to visual changes by surface crystallization. The main goal of the present paper is to assess publica...
The following two earthquakes occurred in Greece during 2019: First, a Mw5.4 earthquake close to Preveza city in Western Greece on 5 February and a Mw5.3 earthquake 50 km East of Patras on 30 March. Here, we present the natural time analysis of the S...
