Mapping Lava Flows on Venus Using SAR and InSAR: Hawaiʻi Case Study

Earth and Space Science
We explore the potential for repeat‐pass SAR Interferometry (InSAR) correlation to track volcanic activity on Venus' surface motivated by future SAR missions to Earth's sister planet.

Elastic Flexure of Young, Overlapping Basaltic Lava Flows Offshore the Galápagos and Hawaiian Islands: Observations, Modeling, and Thermal/Chronological Analysis

Geochemistry, Geophysics, Geosystems, 2020
A recent multibeam bathymetry survey in the Galápagos archipelago revealed a novel observation between the islands of Santa Cruz and Santiago: a steep flexural moat formed between two volcanic flows, nearly 50 m deep and about 500 m wide.

Resolving Micrometre‐Scale Zircon Growth in Silicic Systems by 7 μm LA‐MC‐ICP‐MS U‐Pb Dating: Linking Petrology and Geochronology in Silicic Volcanic and Granitic Rocks from Victoria, Australia

Geostandards and Geoanalytical Research, EarlyView.
Key Points 7 μm spot‐diameter LA‐MC‐ICP‐MS analyses yield accurate zircon U‐Pb ages. 1013 Ω amplifier resistors improve low‐signal Pb measurements. Saturn correction protocols minimise down‐hole fractionation effects. We present a systematic evaluation of high spatial‐resolution zircon U‐Pb dating using a Thermo Scientific Neoma multi‐collector ICP‐MS ...

Temporal and morphological eruption characteristics of lava flows from the Holocene La Taza monogenetic cone obtained from petrology and LiDAR imagery (Michoacán, Mexico)

Volcanica
The Holocene La Taza andesitic volcano is one of over 1000 volcanic centers located within the Michoacán-Guanajuato Volcanic Field (MGVF) in central-western Mexico. La Taza (~8500–8200 yr BP) represents one possible eruption style within the field, with

Imaging Point Source Groundwater Discharges in a Confined Coastal Aquifer Using Electrical Resistivity

Groundwater, EarlyView.
Marine electrical resistivity tomography (ERT) is applied to characterize point‐source submarine groundwater discharge (PSGD) along NW Yucatán. ERT observations and forward modeling constrain conduit detectability under varying hydrogeological conditions.

Introduction to special section : Long lava flows.

, 1998
Long lava flows are traditionally considered to form when low‐viscosity lava is erupted at high effusion rates. However, this view has recently been challenged. Detailed field measurements on active lava flows on Kilauea have shown that inflation of lava

Topography and Volcanology of the Huangtsuishan Volcano Subgroup, Northern Taiwan

Terrestrial, Atmospheric and Oceanic Sciences, 2010
Combining the shaded relief topography model and the slope map from the Digital Terrain Model (DTM) images, toporaphical map, field occurrences and petrography, the volcanic sequences of the Huangtsuishan Volcano Subgroup (HVS) can be constructed.

Invasive Assessment of Right Ventricular Dysfunction Predicts Periprocedural Outcomes in Patients Undergoing Unplanned Ventricular Tachycardia Ablation

Journal of Cardiovascular Electrophysiology, EarlyView.
Displays bar graphs showing outcome rates stratified by clinical and hemodynamic variables. Asterisks (*) denote statistically significant differences (p ≤ 0.05). “NS” indicates non‐significant comparisons. Percentages are shown above each bar. The top panel corresponds to acute kidney injury (blue bars), and the bottom panel corresponds to acute ...
