Geochemistry, Geophysics, Geosystems, Volume 24, Issue 11, November 2023., 2023 Abstract Coseismic frictional heating and associated hydrothermal fluid circulation play an essential role in the dynamic weakening of seismic faults. However, temperature rise induced by frictional heating during an earthquake is still difficult to constrain. Magnetic properties of fault rocks convey abundant information on faulting processes. In this

Terra Nova, Volume 35, Issue 5, Page 432-439, October 2023., 2023 Abstract The Ţicău area (NW Romania) is part of the collisional zone between the Tisza and Dacia mega‐units. Imaging of Ţicău area's subsurface geological structure will contribute to the understanding of the processes, which controlled its tectonic evolution.

Geophysical Prospecting, Volume 71, Issue 7, Page 1312-1324, September 2023., 2023 Abstract Predicting the peak ground velocity of vibrations is essential to blast mining operations in order to design the charge weights so as not to exceed certain thresholds that prevent damage to buildings and other infrastructure. The problem is usually marred by a large scatter of observed peak ground velocity due to unknown complexities of ...

Source time functions and interference from blast arrays
Geophysical Prospecting, Volume 71, Issue 7, Page 1325-1337, September 2023., 2023 Abstract In this study, we review the principles of blast array design for vibration reduction and we present a parametric Laplace‐domain model to predict source time functions for mine blasts that accounts for the relation between charge weight and frequency. We developed the model for one of Europe's largest iron ore mines, Mt.

Anatomy of an Alpine Bedload Transport Event: A Watershed‐Scale Seismic‐Network Perspective
Journal of Geophysical Research: Earth Surface, Volume 128, Issue 8, August 2023., 2023 Abstract The way Alpine rivers mobilize, convey and store coarse material during high‐magnitude events is poorly understood, notably because it is difficult to obtain measurements of bedload transport at the watershed scale. Seismic sensor data, evaluated with appropriate seismic physical models, can provide that missing link by yielding time‐varying ...

Earth Surface Processes and Landforms, Volume 48, Issue 2, Page 386-405, February 2023., 2023 We investigate the impact of Quaternary climate cycles on denudation rates and fluvial aggradation and incision on Crete, Greece. We find that alluvial channels aggrade during cold and dry periods and incise during warm and wet stages, despite relatively steady denudational supply from the hillslopes.

Geofluids, Volume 2023, Issue 1, 2023., 2023 With significant geological reserves and high resource abundance, the Xujiahe Formation in the Western Sichuan Depression is considered a key target for natural gas exploration and development in continental clastic rocks within the Sichuan Basin. However, this formation remains underdeveloped.

Earth and Space Science, Volume 9, Issue 12, December 2022., 2022 Abstract A 6.0‐magnitude (Mw) earthquake was reported to have occurred in Jiashi County, Xinjiang at 21:27 on 19 January 2020, Beijing time (13:27 UTC). This study applied a stochastic finite‐fault approach based on the dynamic corner frequency (EXSIM) to simulate 23 near‐field stations within a distance of 120 km from the epicenter.

Terra Nova, Volume 34, Issue 5, Page 407-423, October 2022., 2022 Abstract Hazardous ground deformation and landslides occur frequently in the Mila Basin, Algeria and this problem remains unsolved. However, the historical seismicity in the area indicates no severe damage from past earthquakes. For this reason, studies are needed to monitor the slow ground movements and their triggering factors.

Tectonics, Volume 41, Issue 8, August 2022., 2022 Abstract The high‐pressure metamorphic Nevado‐Filábride Complex (NFC) in the Betics mountain range of southeastern Spain exhibits continental and ocean‐derived tectonic units, which are key for understanding the geodynamic evolution of the Western Mediterranean.
