The paper presents retrospective analysis of satellite data the upper troposphere / lower stratosphere over epicentral area destructive earthquake M=6.7, occurred in Tien-Shan territory. We established a well-defined temporal and spatial coherence between temperature perturbations seismic activity. used wavelet to identify spectral variations boundary zone before event.

Attenuation relationships that are used to characterize estimated ground motion often ignore details of the earth’s highly-variable three-dimensional velocity and attenuation structure. Increasingly available attenuation models can be used to refine the expected ground motions. First, some tests are performed to look at the effect of the variability in several parameters, such as crustal attenu...

during the past decades, attempts have been made to develop an early warning system for coming destructive earthquakes a few seconds before the ongoing ground motion. in this paper, a practical method for the early warning of earthquakes in south iran is presented. this region is selected for study because it has high potential for generating earthquakes and has a more complete strong ground mo...

This study uses numerical modeling in combination with rock mass classification approaches to develop tunnel support systems that are safe from earthquakes, ultimately contributing the seismic resilience of important infrastructure. A case Himalayan region Nepal has been considered for assessment supports different geological conditions. For better quality masses (GSI>30), strain-softening m...

Two large earthquakes, the Maduo MS 7.4 earthquake and Menyuan 6.9 earthquake, have been successfully recorded on Chinese mainland, since data of CSES satellite were put into service for prediction work mainland at end April 2020. Obvious variations in O+ density electron found during our weekly processing 5–11 May 2021 28 December 2021–2 January 2022, respectively. warnings impending events ar...

Abstract Volcano‐seismic signals such as long‐period events and tremor are important indicators for volcanic activity unrest. However, their wavefield is complex characterization location using traditional seismological instrumentation often difficult. In 2019 we recorded the full seismic a newly developed 3C rotational sensor co‐located with seismometer on Etna, Italy. We compare performance o...
