Project Grant 2534399
- 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...
- 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 $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...
- This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $335,953 to Purdue University to conduct collaborative research comparing the geochemical and temporal links between volcanism and plutonism in an ancient subduction zone volcano in Washington. The key products of this 3-year project include: Reconstruction of the record of volcanic eruptions and subvolcanic intrusive activity by studying the geochemistry, geochronology, and petrology of...
- 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 Leland Stanford Junior University received a $422,120 Project Grant award from the National Science Foundation Division of Earth Sciences under the Geosciences federal grant program (CFDA 47.050) to develop computational models of volcanic eruptions. The period of performance for this research is from June 15, 2023 through May 31, 2026. Under this award, Stanford will develop computer simulations to model magma flow through volcanic conduits, fragmentation processes, and the generation of...
- 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 from the National Science Foundation's Division of Earth Sciences, under the Geosciences program (CFDA 47.050), provides $410,626 to support research on lava rheology for near real-time forecasting of lava flows. The awardee, the Research Foundation for the State University of New York, will conduct detailed petrographic analyses and viscosity measurements on lava samples from Nyamulagira and Nyragongo volcanoes in the Democratic Republic of Congo. These data will be used to...
- This Project Grant award from the National Science Foundation's Geosciences program (CFDA 47.050) provides $312,929 to Washington State University to conduct collaborative research on the aggregation and electrification of volcanic ash particles. The research aims to enhance understanding of turbulence, ash particle dynamics, and electrification within volcanic plumes, which is critical for improving real-time monitoring and modeling of hazardous volcanic eruptions. The project will involve...
- 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...
COLLABORATIVE RESEARCH: HOW TOPOGRAPHY SHAPES PYROCLASTIC DENSITY CURRENT HAZARDS -PYROCLASTIC FLOWS ? HOT, FAST CURRENTS OF GAS AND VOLCANIC ROCK ? HAVE CAUSED ONE THIRD OF ALL DEATHS IN VOLCANIC ERUPTIONS. SCIENTISTS NEED TO COMMUNICATE THE RISKS OF THESE FLOWS TO THE PUBLIC BY MAKING HAZARD MAPS AND THROUGH PUBLIC INFORMATION ABOUT THE DANGERS. DESPITE THIS NEED, THERE IS A POOR UNDERSTANDING OF HOW HILLS AND VALLEYS IMPACT THE TRAVEL OF PYROCLASTIC FLOWS. THIS PROJECT WILL USE PRODUCTS AND PHOTOGRAPHS OF THE ERUPTION OF MOUNT ST. HELENS ON MAY 18, 1980, TO DOCUMENT HOW THE FLOW REACTED WHEN IT ENCOUNTERED HILLS AND VALLEYS. COMPUTER MODELS WILL BE RUN TO SEE HOW THE SPEED AND OTHER PROPERTIES OF THE CURRENT CHANGE WITH TIME. IN ADDITION TO INCREASING UNDERSTANDING OF PYROCLASTIC FLOWS, THE RESULTS WILL BE USED TO BUILD AN EXHIBIT OF THE ERUPTION TO SHARE WITH SCHOOLS AND MUSEUMS TO HELP EDUCATE THE PUBLIC ABOUT VOLCANIC HAZARDS. SCIENTISTS CANNOT SEE INSIDE DEADLY PYROCLASTIC FLOWS AND SO THEY MUST USE NUMERICAL MODELS TO STUDY THEIR INTERNAL DYNAMICS. MOST SUCH MODELS USUALLY TREAT PYROCLASTIC FLOWS AS HOMOGENEOUS AND DILUTE AND DO NOT ACCOUNT FOR HOW THE FLOWS WILL EVOLVE IN SPACE AND TIME WHEN THEY ENCOUNTER ROUGH TOPOGRAPHY. THIS PROJECT SEEKS TO IMPROVE THE UNDERSTANDING OF HOW TOPOGRAPHY IMPACTS PYROCLASTIC FLOWS BY CREATING A 4D MODEL OF THE FLOW FROM MAPPING ORIENTATIONS OF TREES KNOCKED OVER BY THE CURRENT AS IT TRAVELED ACROSS RUGGED TOPOGRAPHY. THE MODEL WILL ALSO INCORPORATE INFORMATION IN A SERIES OF CLOSELY TIMED PICTURES OF THE MOUNT ST. HELENS ERUPTION TAKEN FROM DIFFERENT LOCATIONS AROUND THE VOLCANO. THE 4D MODEL WILL PROVIDE THE FOUNDATION TO COMPARE COMPUTATIONAL MODELS TO TEST HOW CHANGES IN FLOW VELOCITY, DENSITY, AND TEMPERATURE CONTROLLED THE RESPONSE OF THE FLOW TO REAL-WORLD TOPOGRAPHY. A MOBILE DISPLAY FOR SCHOOLS AND MUSEUMS WILL INCORPORATE THE 4D MODEL AND RECORDED EYEWITNESS ACCOUNTS TO HELP EDUCATE THE GENERAL PUBLIC ABOUT THE HAZARDS AND RISKS OF PYROCLASTIC FLOWS. THIS AWARD REFLECTS NSF'S STATUTORY MISSION AND HAS BEEN DEEMED WORTHY OF SUPPORT THROUGH EVALUATION USING THE FOUNDATION'S INTELLECTUAL MERIT AND BROADER IMPACTS REVIEW CRITERIA.- SUBAWARDS ARE NOT PLANNED FOR THIS AWARD.
