3D Shear Velocity Structure of the Caribbean—Northwestern South America Subduction Zone From Ambient Noise and Ballistic Rayleigh Wave Tomography

Geochemistry, Geophysics, Geosystems, Volume 25, Issue 9, September 2024.
Abstract The Caribbean‐South America subduction zone is a flat subduction zone, with Laramide‐style thick‐skinned uplifts occurring in the Merida Andes, Sierra de Perija Range, and Santa Marta Massif. Geodetic measurements and historical seismicity show this region is storing strain energy and is capable of a mega‐thrust earthquake (M ≥ 8.0).

Recurrent Lightning Spots: Where Lightning Strikes More Than Twice

Journal of Geophysical Research: Atmospheres, Volume 129, Issue 5, 16 March 2024.
Abstract The expression “lightning never strikes twice” is questioned in this paper because, among the randomness of lightning impacts, some spots are hit even more than twice year after year. This article introduces the recurrent lightning spots (RLS) concept, which are locations periodically impacted by cloud‐to‐ground lightning every consecutive ...

Lightning Characteristics Associated With Storm Modes Observed During RELAMPAGO

Journal of Geophysical Research: Atmospheres, Volume 129, Issue 4, 28 February 2024.
Abstract Global satellite studies show a maximum in deep convection and lightning downstream of the Andes in subtropical South America. The Remote sensing of Electrification, Lightning, And Mesoscale/microscale Processes with Adaptive Ground Observations (RELAMPAGO) field campaign was designed to investigate the physical processes that contribute to ...
