Dynamics, interactions and delays of the 2019 Ridgecrest rupture sequence
(2023)
The observational difficulties and the complexity of earthquake physics have rendered seismic hazard assessment largely empirical. Despite increasingly high-quality geodetic, seismic and field observations, data-driven ...
Full Waveform Inversion Based on an Asymptotic Solution of Helmholtz Equation
(2023)
This study considers the full waveform inversion (FWI) method based on the asymptotic solution of the Helmholtz equation. We provide frequency-dependent ray tracing to obtain the wave field used to compute the FWI gradient ...
Is There a Semi-Molten Layer at the Base of the Lunar Mantle?
(2023)
Parameterised by the Love number k(2) and the tidal quality factor Q, and inferred from lunar laser ranging (LLR), tidal dissipation in the Moon follows an unexpected frequency dependence often interpreted as evidence for ...
JUNO sensitivity to 7Be, pep, and CNO solar neutrinos
(2023)
The Jiangmen Underground Neutrino Observatory (JUNO), the first multi-kton liquid scintillator detector, which is under construction in China, will have a unique potential to perform a real-time measurement of solar neutrinos ...
A commercial finite element approach to modelling Glacial Isostatic Adjustment on spherical self-gravitating compressible earth models
(2023)
This paper presents a method that modifies commercial engineering-oriented finite element packages for the modelling of Glacial Isostatic Adjustment (GIA) on a self-gravitating, compressible and spherical Earth with 3-D ...
Broadband Strong Ground Motion Modeling Using Planar Dynamic Rupture With Fractal Parameters
(2023)
Dynamic rupture modeling represents a promising physics-based approach to strong ground motion simulations. However, its application in a broad frequency range (0-10 Hz), interesting for engineering studies, is challenging. ...
Radar Attenuation in Enceladus' Ice Shell: Obstacles and Opportunities for Constraining Shell Thickness, Chemistry, and Thermal Structure
(2023)
Enceladus is a dynamic icy moon of Saturn and a leading target for future planetary missions focused on the search for life beyond Earth. For such missions, instruments that can provide geophysical and geochemical context ...
Heat extraction calculations for deep coaxial borehole heat exchangers: matrix analytical approach
(2023)
Deep boreholes represent a source of clean energy. Therefore, effective calculations of potential extraction of heat from boreholes for realistic models of the Earth's crust with variable thermal conductivity and diffusivity ...
Modelling the seismic response of the Mytina maar volcanic structure
(2023)
In this study, we determine the properties of the maar volcanic structure using ambient vibration analysis. We performed several ambient vibrations surveys at MATIN SMALL LETTER Y WITH ACUTEtina maar (West-Bohemia, Czechia) ...
Long-period directivity pulses of strong ground motion during the 2023 Mw7.8 Kahramanmaras earthquake
(2023)
Damages due to large earthquakes are influenced by broadband source effects that remain enigmatic. Here we develop a broadband (0-10 Hz) source model of the disastrous 2023 Mw7.8 Kahramanmaras, Turkiye, earthquake by ...
