Project Grant 2534398
- The National Science Foundation Office of Integrative Activities awarded the University of Texas at Austin $401,705 on August 1, 2026, under the Geosciences program (CFDA 47.050) to investigate sulfur behavior in the volcanic critical zone with implications for eruption forecasting and gas monitoring. The research investigates how sulfur moves from magma to the surface at well-monitored active volcanoes prone to explosive eruptions, examining sulfur in its gas, dissolved, and solid forms...
- The National Science Foundation Division of Earth Sciences awarded the University of Arizona $654,000 on July 1, 2026, under the Geosciences program to investigate how evolving topography affects lava flow emplacement and eruption hazards. The project analyzes the 2021–2023 Fagradalsfjall eruptions in Iceland, among the most densely observed volcanic events on record, to understand how landforms created by lava emplacement reroute subsequent flows and modify hazard zones. The research applies...
- This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will support research to explore the capabilities of a new technique for measuring the rheology (flow properties) of three-phase basaltic lava. The $261,540 award to the University of Texas at San Antonio will fund experiments using lava collected from eruptions of Mauna Loa volcano in Hawaii. The goal is to better understand how factors like temperature, crystallinity, and bubble content impact...
- The National Science Foundation Office of Integrative Activities awarded the University of Texas at Austin $454,855 on January 1, 2027 under the Geosciences program (CFDA 47.050) to conduct integrated experimental and modeling research on subduction zone earthquake controls. The project will develop a system to distinguish whether shallow subduction faults build energy for infrequent large earthquakes and tsunamis or release stress through small events by measuring the rates of fault healing...
- This National Science Foundation (NSF) Division of Earth Sciences Project Grant award for $180,000 from April 1, 2024 to March 31, 2026 will support research to develop a new "Eruption Stability Diagram" classification system for volcanic eruptions. The objective is to better understand and predict the evolution of volcanic hazards, such as ash clouds and pyroclastic density currents, by accounting for the effects of varying eruption rates and micrometer-scale processes. The research...
- This National Science Foundation award provides $333,856 under the Geosciences program (CFDA 47.050) to the University of Texas at Austin from August 1, 2022 to July 31, 2025. The funding will support the development of a unified numerical model for bubble nucleation and growth in volcanic systems through collaborative research between US and UK investigators. Specifically, the award will combine novel experiments with theoretical modeling to address current knowledge gaps in nucleation...
- This $494,982 Project Grant award from the National Science Foundation (NSF) Geosciences Program (CFDA 47.050) supports a multidisciplinary research effort to reexamine the precursory activity leading up to the catastrophic Mount Mazama eruption in Oregon approximately 7,700 years ago. The research team, led by the University of Oregon, will track changes in the chemistry and physical properties of the magmatic system over time by analyzing ash, pumice, and lava samples from the precursor...
- The National Science Foundation Division of Earth Sciences awarded New Mexico Institute of Mining and Technology $415,488 on August 15, 2026, under the Geosciences program (CFDA 47.050) to conduct multiscale seismic imaging analysis of the Cascadia volcanic arc in the Pacific Northwest. The work examines subsurface magma system structure beneath nine of eleven high or very high threat volcanoes classified by the United States Geological Survey using passive imaging techniques including...
- The National Science Foundation Office of Integrative Activities awarded the University of Texas at Austin $425,000 on August 1, 2026, under the Geosciences program (CFDA 47.050) to develop a probabilistic fault system model based on a cross-validated, second-order damage evolution framework for large continental fault systems. The project develops a new modeling approach to capture uncertainty in fault network behavior, treating faults not merely as fixed geometric features but as systems...
- This $490,303 Project Grant award from the National Science Foundation's (NSF) Geosciences Program (CFDA 47.050) will support a research project aimed at improving the understanding of lava flow properties and their impact on volcanic eruption hazard assessment. The key products and services to be delivered under this award include: Developing and deploying two new field tools to directly measure the viscosity of natural lava flows, which contain critical elements like bubbles and crystals...
The National Science Foundation Office of Integrative Activities awarded the University of Texas at Austin $209,733 on August 15, 2026, under the Geosciences program (CFDA 47.050) to study how topography shapes pyroclastic density current hazards and to develop public education materials about volcanic risk. The project creates a four-dimensional model of the May 18, 1980 Mount St. Helens pyroclastic flow by analyzing tree orientations knocked over by the current as it traveled across rugged topography and integrating closely-timed photographs of the eruption taken from multiple vantage points around the volcano. Researchers will run computational models to simulate how flow velocity, density, and temperature control the response of pyroclastic flows to real-world terrain, addressing a critical gap in hazard understanding—most existing models treat pyroclastic flows as homogeneous and do not account for how flows evolve when encountering rough topography. Because pyroclastic flows have caused one-third of all deaths in volcanic eruptions, improved understanding is essential for communicating risk to the public through hazard maps and public information. The project will produce a mobile educational exhibit incorporating the four-dimensional model and recorded eyewitness accounts for distribution to schools and museums, translating the research findings into public hazard awareness materials. Work is performed at the University of Texas at Austin in Austin, Texas. The period of performance runs through July 31, 2029. The assistance type is a project grant.
