Short summary
Direct-sun solar absorption FTIR and DOAS measurements were performed during the 2021 La Palma eruption from distance up to 140 km. Using FTIR-DOAS gas-to-sulfur ratios and SO2 fluxes derived from TROPOMI, CO2, CO, HCl, HF volcanic emissions were estimated. Estimates of emission budget were found in good agreement with petrologic data. This study demonstrates the feasability of using existing atmospheric monitoring network to monitor volcanic eruptions.

The growing interest in lithium (Li) diffusion for the determination of timescales of magmatic events increases the necessity to better understand Li diffusion in common mineral phases. In this context we analyzed Li diffusion in plagioclase, one of the most common mineral phases. Our study is the first to confirm two diffusion mechanisms for Li in plagioclase, and our results indicate timescales derived from Li diffusion data in previous studies were underestimated by a factor of up to 100.

Lascar volcano, located in northern Chile, is among the most active volcanoes of the Andes. Its activity culminated in the last major explosive eruption in April 1993. We carried out experiments at high temperatures (up to 1050 °C) and pressures (up to 5000 bar) in the lab, and we used a wide variety of geochemical methods to provide comprehensive constraints on the depth and temperature of the magma chamber beneath Lascar volcano.

The new spectroscopic method, based on the syncrotron radiation, allows for determination of Fe oxidation state in tiny objects or in heterogeneous samples. This technique is expected to be an important tool in geosciences unraveling redox conditions in rocks and magmas as well as in material sciences providing constraints on material properties.

Short summary
Volcanoes on Earth are divided into monogenetic and composite volcanoes based on edifice shape. Currently the evolution from monogenetic to composite volcanoes is poorly understood. There are two distinct magma chambers, with a deeper region at the Moho and a shallow mid-crustal zone in the Wulanhada Volcanic Field. The crustal magma chamber represents a snapshot of transition from monogenetic to composite volcanoes, which experience more complex magma processes than magma stored in the Moho.

In this paper we calibrate a new empirical clinopyroxene-only thermobarometer based on new models. The new models show satisfying performance in both calibration and the test dataset compared with previous thermobarometers. Our new thermobarometer has been tested on natural clinopyroxenes in the Icelandic eruptions. The results show good agreement with experiments. Hence, it can be widely used to elucidate magma storage conditions.

Short summary
We studied the exchange of chemical elements by diffusion between magmas of tephritic and phonolitic composition from the Canary Islands, performing experiments at high pressure and high temperature with different amounts of added water. Our results characterize the way water and temperature affect the diffusion process, and we also find unexpectedly high mobility of aluminium, which may be related to its variable chemical bonding in highly alkaline melts.
