This paper presents the strategy and operational tools developed and implemented at the Euro-Mediterranean Seismological Centre (EMSC) to detect and diagnose the impact of global earthquakes within minutes by combining « flashsourcing » (real time monitoring of website traffic) with social media monitoring and crowdsourcing. This approach serves both the seismological community and the public a...

Stress inversion of seismological datasets became an essential tool to retrieve the stress field of active tectonics and volcanic areas. In particular, in volcanic areas, it is able to put constrains on volcano-tectonics and in general in a better understanding of the volcano dynamics. During the last decades, a wide range of stress inversion techniques has been proposed, some of them specifica...

A theoretical relation is presented between the seismological Fourier amplitude spectrumand the mean squared value of the elastic response, which is defined by Gaussian distribution. Byshifting a general process to its mean value, spectrum of the mean squared value of the displacementis computed from the Fourier amplitude spectrum and the real part of the relative displacementtransfer function ...

In this study, a large seismological dataset from the Mesopotamian Network (MP) and Iranian Seismological Center (IRSC) was analyzed to relocate earthquakes with magnitude Mw ≥ 4 for period between August 2014 April 2021 that occurred in Outer Arabian Platform of Iraq. The Computer Programs Seismology (CPS) wrer used purpose. iterative method applied earthquakes. these also calculated using MbL...

This paper presents the results of a six-week unit on seismology conducted in a fifth-grade classroom. The unique feature of the unit involved the use of classroom technology designed to support students' participation in an authentic seismological practice: the interpretation of seismograms to determine the epicenter and magnitude of earthquakes. The goals of the empirical study were (1) to ga...

High-precision modeling of seismic-wave propagation in heterogeneous media is very important to seismological investigation. However, such modeling is one of the difficult problems in the seismological research fields. For developingmethods of seismic inversion and high-resolution seismic-wave imaging, the modeling problem must be solved as perfectly as possible. Moreover, for long-term computa...

We have analyzed a seismological catalog of approximated 103.000 earthquakes with 0.1 ≤ mL ≤ 6.8 and depths ranging between 0 and 200 km. This catalog was estimated by the National Seismological Network of Colombia with 17 stations in the period 1993-2013. Data allowed calculate the spatial variations (dependence with depth) of the seismic regime (fractal dimension of the earthquakes distributi...

A 3-dimensional, fully nonlinear numerical geodynamo model is used to study the core-mantle coupling arising from a non-hydrostatic pressure field acting on an aspherical core-mantle boundary (CMB) based on a seismological model. The simulation results demonstrate that the topographic coupling torque is close to being proportional to the square of the amplitude of the CMB topography. We conclud...
