Abstract In the context of assessing seismic hazard, accurately predicting ground motion stands out as a crucial task. Achieving precision in modeling proves valuable revealing actual pattern, even when faced with insufficient data on soil structure, provided there is precise information about source. This study introduces methodology for calculating local- and near-field motion, expressed peak acceleration (PGA) intensity values. The deterministic approach employed, incorporating source...
Abstract. A rapid growth of population, intensive civil and industrial building, land water instabilities (e.g. landslides, significant underground level fluctuations), the lack public awareness regarding seismic hazard contribute to increase vulnerability Baku (the capital city Republic Azerbaijan) earthquakes. In this study, we assess an earthquake risk in determined as a convolution (in terms surface peak ground acceleration, PGA), (due building construction fragility, population...
Here we present the main features of frontal structure, known as Kur Fault, Plio-Quaternary Kura fold-and-thrust belt in Greater Caucasus (Azerbaijan). The Fault has been analysed thanks to geological-structural and geomorphological surveys its whole length, integrated by a relocation instrumental seismicity, data on historical new focal mechanism solutions, ambient vibration measurements across fault trace. in-depth study structure can: i) provide insights into shallow propagation regional...
Relevance. Azerbaijan is tectonically situated in the Arabian-Eurasian continent collision zone. Due to this activity seismic pattern of region observed with occurrence frequent moderate and occasionally strong earthquakes. Research methods. In study, we used a catalog International Seismological Centre through including neighbor parts aquatory (Caspian Sea). Catalog has been clustered according 6 tectonic mega-zones Azerbaijan. Aim. The purpose paper expose seismicity level employing...
This study evaluates the Soviet-era ground motion prediction equation (named as A&K-1979) and introduces an Artificial Neural Network (ANN)-based GMM specifically designed for Azerbaijan to improve accuracy. Ground models (GMMs) are essential predicting earthquake-induced motions, aiding seismic hazard assessments engineering designs. While traditional linear empirical have been widely used, they often struggle capture complex nonlinear behaviors. The performance of A&K-1979...
Abstract The Greater Caucasus orogen on the southern margin of Eurasia is hypothesized to be a young collisional system and may present an opportunity probe structural, sedimentary geodynamic effects continental collision. We detrital zircon U‐Pb age data from region that constrain changes in sediment routing source exposure during late Cenozoic convergence collision between Lesser Caucasus, arc terrane lower plate system. During Oligocene Middle Miocene time, following initiation...
Abstract. The historical and instrumental catalog of the Absheron-Prebalkhan region in Caspian Sea area was analyzed order to reveal existence temporal clustering time dynamics seismicity. timespan is from 1842 2012 magnitude events ranges 2.5 6.8. Gutenberg-Richter analysis indicates 4.0 as completeness catalog. performed over sequence with M ≥ 4 by using methods Allan Factor coefficient variation. Both have revealed presence time-clusterized structures large region. Such findings, which...
Abstract Orogenic wedges are common at convergent plate margins and deform internally to maintain a self‐similar geometry during growth. New structural mapping thermochronometry data illustrate that the eastern Greater Caucasus mountain range of western Asia undergoes deformation via distinct mechanisms correspond with contrasting lithologies two sedimentary rock packages within orogen. The orogen interior comprises package Mesozoic thin‐bedded (<10 cm) sandstones shales. These strata...
We investigated ground response for Baku (Azerbaijan) from two earthquakes of magnitude M6.3 occurred in Caspian Sea (characterized as a near event) and M7.5 Shamakhi remote extreme event). S-wave velocity with the average shear wave over topmost 30 m soil is obtained by experimental method V P values measured soils. The downtown part city characterized low VS30 (< 250 m/s), related to sand, water-saturated gravel-pebble, limestone clay. High surface PGA 240 gal event about 190 event, hence...
In this paper, earthquake scenarios parameters were assessed for deterministic seis-mic hazard of the southern slope Greater Caucasus (Azerbaijan). Historically, there occurred strong earthquakes in studied region.
