Abstract
This project investigates the magma system beneath K?lauea volcano, hawaii using seismic anisotropy?a phenomenon where seismic waves travel at different speeds depending on the properties of the materials they pass through. The research focuses on understanding how changes in subsurface magma influence volcanic activity, with the goal of improving methods for eruption forecasting. Shear wave splitting (SWS) analysis, which examines how seismic waves split as they travel through different materials, can provide information about subsurface conditions. This study will address fundamental questions about magma transport and the interplay between deep and shallow magma systems, helping to enhance the predictive capabilities for volcanic eruptions. The findings have the potential to enhance eruption forecasting methods, benefiting not only volcanology but also communities and infrastructure near active volcanoes. Conducted at a two-year college, this project also offers students hands-on experience in advanced research techniques and promotes skill development in data analysis and geoscience methodologies. The project aspires to engage the broader community through potential outreach activities, such as presentations and public talks, to foster greater understanding of volcanic processes and hazards. This study utilizes SWS analysis of seismic data collected during the 2018 K?lauea eruption. SWS occurs when seismic waves split into fast and slow components as they pass through anisotropic materials and can provide insights into stress fields, magma flow, and microfracture alignment within a volcanic system. The project will analyze deep earthquakes (>15 KM) near P?hala, a potential magma supply zone, and shallow earthquakes (
