Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.Abstract Caldera systems commonly experience inner resurgence, which shapes patterns of volcanic activity. However, incomplete reconstructions of past ground deformation can lead to incorrect recognition of precursory signals. The Campi Flegrei caldera (Italy) provides an exceptional opportunity to address this issue as uplifted marine sediments ...

Inversion by Intrusion: Magma‐Driven Shortening in the Turkana Rift (East Africa)
Tectonics, Volume 45, Issue 8, August 2026.Abstract Late Pliocene to Pleistocene inversion in the Turkana Rift, observed on seismic reflection data and in outcrop, presents a tectonic paradox by indicating local shortening in an overall extensional setting. Previous studies attributed this inversion either to the reactivation of obliquely oriented structural weaknesses or to reorientation of ...

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.Abstract Unsustainable rates of groundwater (GW) depletion make GW management a priority. Effective GW management is hindered by the uncertainty in the predictions of aquifer models, but the increase of geodetic surface deformation data can improve aquifer characterization.

Linking Interseismic Locking to Coseismic Rupture: The 2025 Mw 8.8 Kamchatka Earthquake
Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.Abstract We investigate interseismic locking on the Kamchatka megathrust, source of the 2025 Mw 8.8 earthquake, using a data‐driven probabilistic framework. Horizontal GNSS velocities constrain a boundary element model on a triangulated megathrust geometry, while an algorithmic sampling strategy estimates the locking probability for fault elements ...

2008年汶川地震震源区东北端局部形变区与青川MS6.4强余震关系
Dizhen xuebao, 2018 2008年汶川地震之后，通过InSAR观测到青川县木鱼镇附近存在一个长约为15 km、宽约为10 km、地表位移数十厘米的局部形变区。前人分析认为，该形变区是由MS6.4的青川强余震造成的，但拟合地表形变数据所采用的震源深度和震源机制解与地震学反演的结果具有较大差异。本文利用远震体波和瑞雷波振幅谱进一步测定了青川强余震的震源深度和震源机制解，计算了此次事件造成的地表位移场，认为青川强余震并非造成木鱼镇地区局部形变的直接原因，并讨论该局部形变区可能的成因。

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.Abstract The NASA/CNES Surface Water and Ocean Topography (SWOT) swath‐mapping radar altimetry satellite mission, launched in December 2022, provides repeat‐track coverage to about ±78.2° latitude every 21 days, sampling many of Antarctica's most dynamic ice shelves that play key roles in constraining mass loss from the grounded ice sheet ...

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.Abstract We analyze and model ground deformation at Masaya volcano, Nicaragua, using Sentinel‐1 Interferometric Synthetic Aperture Radar (InSAR) time series spanning January 2018–February 2024. Time series show the Masaya Central Reservoir (MCR) experienced ∼3 cm of line of sight (LOS) displacement away from the satellite north of the Santiago crater ...

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.Abstract Large earthquakes often elevate seismicity in surrounding regions, as seen on the Xainza‐Dinggyê rift in southern Tibet after the 2015 MW 7.8 Gorkha (Nepal) earthquake. In contrast, the EW‐trending Yarlung Zangbo suture (YZS), located directly north of this event, exhibits seismic quiescence.
