Timescales of magmatic processes and eruptive histories are fundamental pieces of information required for understanding magmatic systems, and which can contribute to improve short- and long-term eruption forecasting. For example, timescales and rates of crystallisation, degassing and magma ascent are crucial for understanding magma residence, magmatic differentiation, and the driving forces leading to eruption. Knowledge about timing and frequency of past eruptions is essential for accurate hazard assessment, as well as for understanding long-term magmatic evolution at a volcano. Current development of novel methods, and continued advances in existing analytical and imaging techniques mean that elements, isotopes and rock textures can be measured and analysed at ever improving precision and spatial resolution. We encourage contributions which investigate magmatic timescales and volcanic histories, using a range of techniques including but not limited to, geochronology and radioisotopic dating, uranium-series isotopic analysis, field studies, diffusion modelling and quantitative textural studies.
