GNSS Observations of the Land Uplift in South Africa: Implications for Water Mass Loss

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 4, April 2025.
Abstract Continuously operating Global Navigation Satellite System (GNSS) base stations in South Africa show a spatially coherent vertical displacement. While one hypothesis attributes this vertical motion to crustal deformation from mantle flow and dynamic topography (Hammond et al., 2021, https://doi.org/10.1029/2021jb022355), we propose an ...

Inferring Eruption Dynamics From Seismometer Tilt: A Case Study of Erebus and Augustine Volcanoes

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 4, April 2025.
Abstract Broadband seismometers are sensitive to tilt as a consequence of their design. We used broadband data from Erebus volcano on Ross Island, Antarctica, and Augustine volcano in Lower Cook Inlet, Alaska, to make tilt measurements associated with individual volcanic explosions and investigate the near‐terminal magmatic system configuration of each

Separating Magmatic and Hydrothermal Deformation Using InSAR Timeseries: Independent Component Analysis at Corbetti Caldera, Ethiopia

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 4, April 2025.
Abstract The cause of unrest at large quaternary silicic calderas, specifically whether the source is magmatic or hydrothermal, has critical implications for the potential eruptive hazard and is debated, even at well‐studied systems. Recent advances in Interferometric Synthetic Aperture Radar (InSAR), driven by the Sentinel‐1 mission, allow us to ...

Sensitivity of the Shallow‐To‐Deep Convective Transition to Moisture and Wind Shear in the Amazon

open access: yesJournal of Advances in Modeling Earth Systems, Volume 17, Issue 4, April 2025.
Abstract Deep convection is the primary influence on weather and climate in tropical regions. However, understanding and simulating the shallow‐to‐deep (STD) convective transition has long been challenging. Here, we conduct high‐resolution numerical simulations to assess the environmental controls on the evolution of isolated convection in the Amazon ...
