Modelling the Importance of Ground and Strong‐Motion Variables on the Damage Status in the 2023 Kahramanmaraş Earthquakes Using Supervised Machine Learning

Geoscience Data Journal, Volume 12, Issue 4, October 2025.
KNN achieved the highest performance (0.989) using the full dataset and 0.988 with ground‐based parameters. EBd and f0 were key contributors to damage, while PGA dominated strong‐motion models. Specificity consistently outperformed sensitivity in earthquake‐parameter models.

Notranja oksidacija Cu-C in Ag-C kompozitov [PDF]

, 2012
The internal oxidation in copper-carbon and silver-carbon composites occurs when they are exposed to air or oxygen at high temperature. Solubility of carbon in copper or in silver is very low.

Regional mapping of sediment thickness using microtremor HVSR spatial variability

Discover Geoscience
The microtremor Horizontal-to-Vertical Spectral Ratio (HVSR) method is widely adopted for estimating site fundamental frequency ( $$\:{f}_{0}$$ ) and sediment thickness due to its simplicity and cost-effectiveness. However, current applications typically

Shear wave velocity model using HVSR inversion beneath Bandar Lampung City[Key points]

Earthquake Science
The horizontal-to-vertical spectral ratio (HVSR) method has been used to characterize site-effect parameters that are indispensable in seismic hazard and risk-reduction studies in urban areas and rapid land-use planning.

Subtle relict channels associated with large dolines in an area formerly beneath the Laurentide Ice Sheet, northern Ohio, USA

Boreas, Volume 54, Issue 4, Page 567-589, October 2025.
Low‐relief dry channels appear out of place across a glaciated karst landscape in northern Ohio. Channels are only a few metres deep cut into limestone and draped with a veneer of till. Several hypotheses are proposed for explaining the channels. Low‐relief dry channels are observed across the Bellevue‐Castalia Karst Plain of north‐central Ohio, USA ...

Recorded displacements in a landslide slope due to regional and teleseismic earthquakes [PDF]

, 2015
Regional and teleseismic earthquakes can induce displacements along joints in a landslideinvolved rocky slope in Central Italy. The rarity of these effects is due to specific physical properties of the seismic signals associated with: (i) the energy ...

Investigation of the structure and dynamic response of granite weathering crust slopes based on microtremor recordings: A case study of a landslide in Lishui, Zhejiang Province

Zhongguo dizhi zaihai yu fangzhi xuebao
Granite weathering crust slopes are widely distributed in southeastern China and are highly susceptible to mass landslides during rainy events. Investigating the structure of granite weathering crust slopes and studying the dynamic responses of these ...

Combining 3‐D Deep Electrical Resistivity Tomography With Magnetic Surveys to Investigate Complex Tectonic Basins: A Case Study From the Central Apennines Seismic Belt (Italy)

Tectonics, Volume 44, Issue 9, September 2025.
Abstract We use an innovative geophysical approach to reconstruct the deep structure of Campo Felice, an important extensional basin in the central Apennines (Italy) where active crustal extension is accommodated by normal faults capable of generating earthquakes of magnitude MW 6+.

Quantifying Groundwater Response and Uncertainty in Beaver‐Influenced Mountainous Floodplains Using Machine Learning‐Based Model Calibration

Water Resources Research, Volume 61, Issue 9, September 2025.
Abstract Beavers (Castor canadensis) alter river corridor hydrology by creating ponds and inundating floodplains, and thereby improving surface water storage. However, the impact of inundation on groundwater, particularly in mountainous alluvial floodplains with permeable gravel/cobble layers overlain by a soil layer, remains uncertain.
