Transcrustal magma ascent beneath Laguna del Maule, Chile

J. N. Bradford, Sankha Subhra Mahanti, E. Kiser, Susan Beck et autres

Abstract Arc volcanoes are fed by complex networks of storage zones that extend throughout the crust. Though the geometric details of these transcrustal magmatic systems are well resolved beneath several volcanic settings, the relationship between magma transport at depth and volcanic unrest …

Variations in Subducted Plate Crustal Thickness Along the Perú–Chile Margin and Implications for Slab Dip

Valeria Cortés-Rivas, Ryan Porter

Abstract We use receiver function analysis to calculate the first regional‐scale estimate of subducted oceanic plate crustal thickness along the Perú‐Chile Subduction Zone (PCSZ). Previous studies have shown that the thickness of the subducting crust varies significantly along the margin and influences …

The Anatomy of a Modern Cordillera Style Mountain System: Northern Chile and Argentina

J. N. Bradford, S. L. Beck, E. Kiser, Ryan Porter et autres

Abstract The Central Andean Cordillera between 22°–24°S contains among the highest elevations and largest ignimbrite eruptions on Earth. Cenozoic crustal shortening is a major contributor to orogenic thickening and, while deformation in the upper crust is reasonably well constrained, deeper crust and …

The Anatomy of a Modern Cordillera Style Mountain System: Northern Chile and Argentina

Jim Melvin Bradford, Susan Beck, E. Kiser, Ryan Porter et autres

Key Points1. Receiver Functions in the Central Andes (~22⁰S -24 ⁰S) show greatly resolved cross-cordillera architecture of the crust and upper mantle 2. The South American continental Moho exhibits complex topography related to piece-meal delamination of the lower crust.3. Discontinuities in the …

Enhanced Seismic Backscattering for Lava Tube Detection

Jingchuan Wang, N. C. Schmerr, Naoma McCall, S. Kruse et autres

Abstract Lava tubes, a common volcanic feature on terrestrial planets, offer critical insights into lava flow processes and may serve as future potential habitats for space crews and other facilities on the Moon and Mars. Seismic detection of these features is challenging …

Deformation of the “Anorogenic” Wolf River Batholith, Wisconsin, USA: Understanding the Baraboo Orogeny Hinterland

John P. Craddock, David H. Malone, Erica Powers Craddock, Steven J. Baumann et autres

The Mesoproterozoic (~1470 Ma) Wolf River batholith (WRB) is exposed over 6500 km2, encompassing 11 plutons that crosscut the Archean Marshfield and Proterozoic Penokean terranes. As the WRB is the classically defined anorogenic batholith, to test this hypothesis, seven igneous phases were …

Distributed Acoustic Sensing for Future Planetary Applications: Initial Results From the San Francisco Volcanic Field, a Lunar Analogue

Nicholas Harmon, Ryan Porter, Catherine A. Rychert, N. C. Schmerr et autres

Abstract Seismic imaging is one of the most powerful tools available for constraining the internal structure and composition of planetary bodies as well as enabling our understanding planetary evolution, geology, and distribution of natural resources. However, traditional seismic instrumentation can be heavy …

Characteristics of debris-flow-prone watersheds and debris-flow-triggering rainstorms following the Tadpole Fire, New Mexico, USA

Luke A. McGuire, Francis K. Rengers, Ann Youberg, Alexander Gorr et autres

Moderate- or high-severity fires promote increases in runoff and erosion, leading to a greater likelihood of extreme geomorphic responses, including debris flows. In the first several years following fire, the majority of debris flows initiate when runoff rapidly entrains sediment on steep …
