High‐Resolution Lithospheric Shear Velocity Structure of the Suqian Segment of the Tanlu Fault Zone From Ambient Noise Tomography

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 5, May 2025.
Abstract To understand causes of the Suqian seismic gap and the 1668 M8.5 Tancheng earthquake, we determine a new 3‐D S‐wave velocity (Vs) model of the lithosphere under the Suqian segment of the Tanlu fault zone in eastern China using ambient noise tomography. Rayleigh wave phase velocity dispersions at periods of 5–33 s are collected from seismograms

Scattering and Absorption Imaging of the Hengill High‐Temperature Geothermal Area, Southwest Iceland

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 5, May 2025.
Abstract We applied 3D scattering and absorption imaging to the Hengill volcanic area (southwest Iceland), where high‐enthalpy geothermal reservoirs are presently harnessed. These techniques have shown the potential for detecting magmatic intrusions and fluid reservoirs in volcanic regions.

Formation of Pancake Domes on Venus as Viscous Flows Over an Elastic Lithosphere

Journal of Geophysical Research: Planets, Volume 130, Issue 5, May 2025.
Abstract Venus' steep‐sided domes are circular volcanoes ∼10s of km wide and ∼1 km tall, which are known for their characteristic flat tops and steep sides. However, their composition remains mysterious. These “pancake” domes are likely formed by a high‐viscosity lava, and other studies have predicted a range of compositions, from rhyolite to basalt ...

Coronae on Venus: An Updated Global Database and Insights Into Morphology, Spatial Distribution, Geological Setting, and Lithospheric Properties

Journal of Geophysical Research: Planets, Volume 130, Issue 5, May 2025.
Abstract Venus' surface hosts many volcanic and tectonic features, among which coronae are widespread. Despite their inferred significance for Venus' geodynamics, existing corona databases have been incomplete and/or inaccessible. Here, we present an updated database of coronae, which integrates and validates existing data sets while incorporating new ...
