A repository-hosted dataset of volcanic ash particle images and features.

ABSTRACT: Volcanic ash is made of particles smaller than 2 mm and is produced during volcanic eruptions. Studying the properties of volcanic ash is key for a range of applications, including volcano monitoring. However, given the large variety of textures, colors, and shapes of particles from different eruptions and volcanoes it is challenging to classify them in a reproducible and systematic manner. Here, we present an open access repository-hosted dataset of 11,808 particles from 53 samples across 13 volcanoes. Particle data includes optical microscope images, physical characteristics of the shape, texture and color, and a classification label with the particle type (free-crystal, altered material, juvenile or lithic). The dataset has already been used to develop particle classifiers with Machine
