DOI: 10.1002/2017tc004519
Abstract: SKS, SKKS, and PKS splitting parameters measured at 34 seismic stations that we deployed in the vicinity of the Cenozoic Malawi Rift Zone (MRZ) of the East African Rift System demonstrate systematic spatial variations with… read more here.

DOI: 10.1007/s00445-020-01391-7
Abstract: The composition of gas emitted from a volcano producing basalt magma can vary during an eruption and according to the volcano-tectonic setting of the degassing vents. Post-eruptive filter-pack gas samples from the 2014–2015 Holuhraun crater… read more here.

DOI: 10.1016/j.epsl.2017.11.040
Abstract: Abstract The Baikal Rift Zone (BRZ) is an active intracontinental rift zone with almost no rift-related magmatism along the rift axis. Most magmatism is observed outside the rift center, and e.g. the major Vitim volcanic… read more here.

DOI: 10.1093/petrology/egx051
Abstract: The timescales of magma genesis, ascent, storage and degassing at Kı̄lauea volcano, Hawai‘i are addressed by measuring U-series radionuclide abundances in lava and tephra erupted between 1982 and 2008. Most analyzed samples represent lavas erupted… read more here.

DOI: 10.3103/s0145875217030073
Abstract: Rift systems are composed of a set of heterogeneous tectonic blocks that deform under regional extension concordantly, but individually. Such coordination is achieved due to development of evolving ensembles of deformation structures along the borders… read more here.
