Time-dependent frictional properties of granular materials used in analogue modelling: implications for mimicking fault healing during reactivation and inversion [PDF]

open access: yesSolid Earth, 2023
Analogue models are often used to model long-term geological processes such as mountain building or basin inversion. Most of these models use granular materials such as sand or glass beads to simulate the brittle behaviour of the crust.

Application of active-source surface waves in urban underground space detection: A case study of Rongcheng County, Hebei, China

open access: yesEarth and Planetary Physics, 2022
Active-source surface wave exploration is advantageous because it has high imaging accuracy, is not affected by high-speed layers, and has a low cost; thus, it has unique advantages for investigating shallow surface structures.

Surface wave imaging using deep reflection seismic data: a study on the Cuonadong dome

open access: yesEarth, Planets and Space, 2022
As interference waves in deep reflection data processing, surface waves are often suppressed as noise, but surface waves carry considerable underground media information, including structural information and the physical properties of rocks.

Possible Correlations between the ULF Geomagnetic Signature and Mw6.4 Coastal Earthquake, Albania, on 26 November 2019

open access: yesEntropy, 2021
An earthquake of Mw6.4 hit the coastal zone of Albania on 26 November 2019, at 02:54:11 UTC. It was intensively felt at about 34 km away, in Tirana City, where damages and lives lost occurred.

Kinematics and Convergent Tectonics of the Northwestern South American Plate During the Cenozoic

open access: yesGeochemistry, Geophysics, Geosystems, 2023
The interaction of the northern Nazca and southwestern Caribbean oceanic plates with northwestern South America (NWSA) and the collision of the Panama‐Choco arc (PCA) have significant implications on the evolution of the northern Andes.

Anomalous Geomagnetic Signal Emphasized before the Mw8.2 Coastal Alaska Earthquake, Occurred on 29 July 2021

open access: yesEntropy, 2022
A very strong earthquake of magnitude Mw8.2 struck the coastal zone of Alaska (USA), on 29 July 2021. This earthquake was felt around the Gulf of Alaska, on a wide offshore area belonging to USA and Canada.

UPPER MANTLE CONVECTION RELATED TO SUBDUCTION ZONE AND APPLICATION OF THE MODEL TO INVESTIGATE THE CRETACEOUS-CENOZOIC GEODYNAMICS OF CENTRAL EAST ASIA AND THE ARCTIC

open access: yesГеодинамика и тектонофизика, 2021
A geodynamic model of upper mantle convection related to the Pacific subduction zone is mathematically substantiated and applied to investigate the Cretaceous-Cenozoic evolution of Central East Asia (CEA) and the Arctic. We present a solution for the two-

Smart Speed Imaging in Digital Image Correlation: Application to Seismotectonic Scale Modeling

open access: yesFrontiers in Earth Science, 2019
Analog models of earthquakes and seismic cycles are characterized by strong variations in strain rate: from slow interseismic loading to fast coseismic release of elastic energy.

Seismotectonics of Mongolia and Baikal Rift Zone Controlled by Lithospheric Structures

open access: yesGeophysical Research Letters, 2022
Active tectonics are developing in Mongolia and the Baikal rift zone, where large crustal earthquakes (Mw ≥ 6.0) occur frequently. To clarify the mechanism of these earthquakes, we determine a high‐resolution 3‐D P‐wave velocity model of the crust and ...
