DOI: 10.1016/j.jvolgeores.2018.03.009
Abstract: Abstract Winds and temperature gradients greatly affect the long-range propagation of infrasound. The spatio-temporal variability of these parameters must therefore be accurately characterized to correctly interpret recorded infrasound at long distances, specifically to differentiate between… read more here.

DOI: 10.1016/j.jvolgeores.2020.106997
Abstract: Abstract Present efforts in volcano monitoring, particularly in Southeast Asia, rely on the combination of local data (generally gathered at less than 100 km from the volcano), and satellite remote sensing. While this combination has its… read more here.

DOI: 10.1016/j.jvolgeores.2020.107154
Abstract: Abstract Long-term instrumental monitoring of open-vent volcanoes provides the necessary datasets to characterize volcanic activity and unravel its temporal changes. This is particularly important for active lava domes, which can undergo rapid transitions in behavior… read more here.
