Newberry Volcano Seismic Slowness Model and Processing Code

Encompassing a three-dimensional seismic slowness model and associated MATLAB and Python processing code derived from P-wave data at Newberry Volcano in central Oregon. The model targets the shallow crust to approximately 10 km depth, combining active-source and teleseismic data from the 2008 Newberry Seismic Experiment. It was produced as part of the DEEPEN geothermal project.

Use Cases

• Apply the provided MATLAB or Python workflow to compute fractional velocity perturbation (dv/v) volumes from the 1D and 3D slowness models.
• Use the three-dimensional slowness model to generate horizontal slices and vertical sections for visualizing upper-crustal structure beneath Newberry Volcano.
• Integrate the active-source first-arrival travel times and teleseismic P-wave delay times for joint inversion studies of volcanic regions.
• Reproduce the processing steps from the 2008 Newberry Seismic Experiment data to validate or extend the seismic tomography results.

Strengths

• Includes both a three-dimensional slowness model and the complete processing code (MATLAB and Python) used to generate it.
• Derived from a joint inversion combining two distinct data types: active-source first-arrival travel times and teleseismic P-wave delay times.
• Targets a specific, scientifically relevant depth range for volcanic studies: the shallow crust to approximately 10 km depth.
• Associated with a funded research project (DEEPEN) and experiment (2008 Newberry Seismic Experiment), providing documented provenance.

Limitations

• The dataset consists primarily of processed model outputs and code, not the raw seismic waveform data, which is archived separately.
• The spatial coverage is limited to the specific volcanic edifice of Newberry Volcano in central Oregon.
• The underlying seismic data from the primary experiment is from 2008, which may not reflect current subsurface conditions.

Provenance

Source

Data originates from the 2008 Newberry Seismic Experiment, funded by USGS and NSF grants, and was uploaded to the Geothermal Data Repository (GDR).

Collection Method

Derived from P-wave seismic data via a joint inversion workflow combining active-source and teleseismic measurements.

Time Range

The primary seismic experiment was conducted in 2008, though the dataset references earlier experiments from 1983 and 1984.

Freshness

The dataset metadata was last updated in March 2026, though the core data originates from a 2008 experiment.

Geography

Newberry Volcano in central Oregon, USA.
