1: Generate raw DInSAR and integrated DInSAR+GNSS time series for eruptive events.2: Model volcanic source parameters for each event using DInSAR+GNSS time series, which contain 3 components of motion (east-west, x; north-south, y; and up-down, z). 3: Create synthetic training data related to DInSAR+GNSS. One training set is only time-sensitive and one has dual spatiotemporal components.4: Apply machine learning to both the time-sensitive data and the spatiotemporal-sensitive data. Compare the effectiveness/efficiency of the algorithms to accurately estimate future ground displacement. Determine the role that spatial information plays in reliably forecasting potential volcanic unrest.Integrated geodetic time series that capture the pre, co, post-phases of an eruption create a baseline for deformation patterns leading to hazardous events, can forewarn scientists to impending disasters, and distinguish between deformation types (volcanic, tectonic, hydrothermal, etc). Modeling volcanic source geometry helps map subsurface structure and magmatic parameters as 3D observations, and generates synthetic training data to teach machine learning algorithms to detect anomalous ground motions through time. Analyzing the influence of the spatial field within training data is the first step towards achieving consistent, reliable forecasts. These results will lead to fundamental understanding of the evolution of volcanic eruptions and will constrain subsurface transport pathways from surface deformation patterns.High-resolution Digital Surface Models (DSMs) are also a major goal of this project. DSMs depict the Earth’s topographic surface at sub-meter resolution and can be used to identify areas of elevation change through time, or calculate the total volume of material involved in a hazardous event. DSMs can also improve deformation estimates or be used to remove topographic error in DInSAR. DSM differencing can supplement decorrelated regions in SAR images.
