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.

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

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).

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 ...

Image source detection for geoacoustic inversion by Teager-Kaiser energy operator [PDF]
, 2014 This letter presents an improvement of the image source method (ISM) for geoacoustic inversion. The new algorithm is based on the Teager-Kaiser Energy Operator which ampli es the discontinuities in signals while the soft transitions are reduced.

A note on the Smarandache inversion sequence [PDF]
, 2007 In a recent paper, Muneer introduced the Smarandache inversion sequence. In this paper, we study some properties of the Smarandache inversion sequence. Moreover, we find the necessary and su±cient condition such that [SI(n)]2 + [SI(n + 1)]2 is a perfect
