Reactivation Mechanism of Dormant Earthflows: Insights From the San Benedetto Landslide (Northern Apennines, Italy)

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.
Abstract Earthflows are landslides in fine‐grained materials that alternate long dormant phases of very slow movement with short paroxysmal stages of rapid motion. These rapid phases are highly destructive, often causing severe damage to buildings and infrastructure.

Temporal Variations in Seismic Ambient Noise Identify Seasonal Changes in Basal Conditions at Sermeq Kujalleq in Kangia, Greenland

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Subglacial processes are key to glacier dynamics but remain poorly constrained due to limited in situ observations. We use continuous seismic and Global Navigation Satellite System (GNSS) measurements to investigate summer basal conditions at Sermeq Kujalleq in Kangia (SKK; Jakobshavn Isbræ), Kalaallit Nunaat (Greenland).

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.

Suitability of Ground‐Motion Models for Seismic Hazard Assessments in Puerto Rico and the US Virgin Islands

Earthquake Spectra, Volume 42, Issue 2, May 2026.
We perform linear mixed‐effects analyses with a ground‐motion dataset to evaluate how well ground‐motion models (GMMs) fit active crustal, subduction interface, and subduction intraslab earthquakes in Puerto Rico and the US Virgin Islands. Most of the GMMs reproduce the spatial variation in peak ground motions with earthquake magnitude and rupture ...

Strong Interference HVSR Data Processing and Denoising: HVSR Curve Reconstruction Method based on UPEMD

, 2023
Urban areas pose a challenge for the application of the H/V method due to a high degree of artificial noise. The existing methods fall short in reducing the noise of strong interference data.
