Scientists use a laser diffraction particle size analyzer to examine fine ash from the 2018 Kīlauea summit explosions. The research examines fine ash (grains 1 mm to 1 micrometer) and investigates the processes of eruption, fragmentation, and respiratory health hazards (PM10, PM2.5). USGS image by A. Van Eaton
