AbstractThe paper presents a general outline of the phenomenological theory of aftershocks, i.e., subsequent shocks that occur in the source volume after the main shock. It is proposed to describe the evolution of aftershocks in time by the logistic Ferhulst equation. Apparently, the well-known Kolmogorov–Petrovsky–Piskunov (KPP) equation can serve...

A man-induced seismic activation occurring near the Bachat open-cast coal mine in Kuzbass is studied. The Bachat earthquake of June 18, 2013 (ML = 6.1) is the world’s largest man-made earthquake related to the extraction of solid minerals. It created a powerful aftershock process. More than 3000 earthquakes have been recorded. It was found that the...

AbstractThe fractal properties of seismicity and active faults in Balkans have been studied on the basis of data for distribution of earthquakes and active fault structures in the region. It was found that the fractal dimension of the area distribution of earthquake epicenters for the Balkans dE is 1.74, the fractal dimension of the time distributi...

AbstractA short-lived but violent explosive eruption occurred on the small volcanic island Raikoke in June 2019 (central Kuril Islands). The culmination of the eruption lasted 3.5 h and the ash cloud rose to a height of 13 km. An analysis of a sequence of satellite images in combination with ground-based observations gave information on the pyrocla...

AbstractThe Peruvian part of the Andean volcanic belt (AVB) is characterized by significant mineralization. There are explored Au-Ag epithermal, Cu-porphyry, skarn, Fe-oxide (IOCG-type) and polymetallic deposits. The metallogeny of the AVB is determined by the subduction process, i.e., the underthrusting of the Nazca oceanic plate under the margin ...

AbstractThis study is concerned with Western and Central Tien-Shan. It is an area of intracontinental collision and is of great interest for the study of the geodynamic processes that are occurring in the crust. The area of study was investigated using the method of seismotectonic deformation (STD). The STD was calculated on the basis of the approa...

AbstractThe extrusion of lava domes, their potential collapse, and subsequent pyroclastic flows represent volcanic hazards. Using high-resolution time-lapse images and numerical modeling, we study here the morphological changes of the lava dome formed at Volcán de Colima between February and March 2013 and assess the rheological properties of the d...

AbstractThis paper presents results of multidisciplinary geochronologic, paleoseismic, and tectonophysical studies for local structures in the Sloboda tectono-dynamic intersection that is a segment of the junction between major tectonic structures in the East European Platform. These studies were conducted in the area of the Vitebsk–Surazh fault in...

AbstractUrban development and construction of high-rise buildings in Kuwait have recently increased precipitately. For this reason, creating a seismic code for residential areas in Kuwait has become essential. This exertion to acquire precious results is the first step toward creating a unified earthquake code for the residential areas in the State...

AbstractThe geological, petrographic, and geochemical features detected in the Upper Pliocene acid volcanic rocks sampled in the Upper Chegem and Lower Chegem volcanic highlands provide evidence that the Upper Chegem volcanic rocks are not tuffs that have been subaerially transported from the Upper Chegem Highland; they came from several local cent...
