Stromboli 1930 Pyroclastic Flow 3D Models and Orthophotos

3D reconstructions and orthophotos of two exposures from the 1930 pyroclastic density current on Stromboli volcano. The data was captured via photogrammetry on July 28, 2021, by researchers including Dr Irene Manzella, to support grain size analysis by measuring volume change before and after physical sampling.

Use Cases

• Conduct grain size analysis by comparing volume change in the 3D models before and after physical sample collection.
• Perform geospatial analysis of outcrop features using the orthophotos and UTM coordinate locations (e.g., S_0518638 4295048).
• Use the 3D models to study the morphology and depositional characteristics of the 1930 pyroclastic density current deposits.

Strengths

• Data includes precise UTM coordinate locations for two distinct outcrop sites.
• Models created using structure-from-motion photogrammetry and AGISOFT software, a standard method in geosciences.
• Data collection was conducted by named experts (Dr Irene Manzella, Dr Paul Cole, Symeon Makris).

Limitations

• Dataset scope is limited to two specific geographic locations on Stromboli.
• Sample data, file formats, and dataset size are unknown, hindering immediate usability assessment.
