Erupted Volume During the 2014–2023 Semisopochnoi Unrest and Eruption Constrained by Multi‐Platform InSAR and Volcanic Gas Observations

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Volcano deformation data provide important constraints on magma dynamics during volcanic unrest and eruptions. From these observations, we can estimate subsurface pressure changes and relate them to volume change in the reservoir. However, because magma and rock are compressible, this volume change cannot be directly equated with eruptive ...

Key Parameters for the Ionospheric Detection of Tsunamis From the 29 July 2025 Kamchatka Event

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract It has been demonstrated that tsunamis generate internal gravity waves (GWs) detectable in the ionosphere within 20–60 min after their generation at the ocean surface. Despite numerous simulation and observation studies on ionospheric signatures of tsunamis, the detection of Co‐tsunamic Ionospheric Disturbances (CTIDs) and distinguishing them ...

Tectonic Model of the 2021 Haiti Earthquake Based on a Newly‐Formed Strike‐Slip Bypass Fault Across a Paired Restraining‐Releasing Bend

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract On 14 August 2021, the southern peninsula of Haiti was struck by an Mw 7.2 earthquake that killed more than 2,200 people. The 2021 epicenter is located 95 km west of the Mw 7.0 2010 Haiti earthquake and 7 km north of the main, geomorphic trace of the EW‐striking, left‐lateral strike‐slip Enriquillo‐Plantain Garden fault zone (EPGFZ) that forms

Using Phase Unwrapping Methods to Apply D-InSAR in Mining Areas

Canadian Journal of Remote Sensing, 2019
Phase unwrapping is one of the key processing steps of D-InSAR (Differential Interferometric Synthetic Aperture Radar), and its accuracy has a great impact on the accuracy of interferometric deformation results. Therefore, it is necessary to choose the proper phase unwrapping method for mining deformation monitoring with different coherence by the ...

Microgravity Measurements Spanning 2019–2022 Indicate No Change in Magma Supply or Storage During Kīlauea's Reawakening

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract After more than 2 years of quiescence following its major 2018 flank lava effusion and summit caldera collapse, Kīlauea, Hawaiʻi, returned to frequent eruptive activity in late 2020. Microgravity measurements from the summit region in 2019 and 2022 span this reawakening and indicate a gravity increase of up to hundreds of microgals near the ...
