However, most dike intrusions never reach the surface and instead become arrested at depth. A grand challenge in volcanology is to determine what governs the propagation direction of dikes in the shallow crust. More broadly, the dynamics of hydraulic fractures influence a number of earth processes such as calving of glaciers, deposition of ore deposits, and extraction of geothermal energy. While geophysical data can indirectly record dike intrusion events in real time, ancient magma plumbing systems exposed within the eroded remnants of volcanoes reveal clues about the style and 3D nature of magma transport. By integrating geophysical data, geological observations, and physics-based modeling, we can address the following questions: Why do dikes within the upper few kilometers of the crust tend to propagate laterally instead of erupting closer to their source? How does the evolution of pressure and magma properties within the source reservoir influence dike dynamics? How can we better predict in real-time whether and where a dike will erupt? This paper from JGR: Solid Earth summarizes key findings related to the May 2018 dike intrusion and eruption at Kīlauea. https://images.squarespace-cdn.com/content/v1/5fce75afd0d2f13be8116dfc/1607375017214-4V990YMJ1PGUJL97ND1D/DJI_0555.JPG Projects https://www.meredithtownsend.com/pubs daily 0.75 2025-10-29 https://www.meredithtownsend.com/group daily 0.75 2024-10-08 https://images.squarespace-cdn.com/content/v1/5fce75afd0d2f13be8116dfc/1607372159428-53YO1TNI1TM9BKC8V7KZ/kate_headshot.jpg Group https://images.squarespace-cdn.com/content/v1/5fce75afd0d2f13be8116dfc/51312e38-5085-44f8-a726-94925603c55d/gui_profile_pic.jpg Group https://images.squarespace-cdn.com/content/v1/5fce75afd0d2f13be8116dfc/2fadccd2-9907-4f48-934e-79426121efbe/Franzi.jpg Group https://images.squarespace-cdn.com/content/v1/5fce75afd0d2f13be8116dfc/5c6713b5-e7dd-47bc-a555-4a472567f5b9/headshot_2023.jpg Group https://www.meredithtownsend.com/opportunities daily 0.75 2025-10-29 https://images.squarespace-cdn.com/content/v1/5fce75afd0d2f13be8116dfc/cdb57a1d-adb0-4984-94de-adac0d8c2b95/IMG_4945.jpg
