DOI: 10.1007/s00410-018-1542-6
Abstract: Throughout the last 35 ka, Mount St. Helens has been the most active volcano in the Cascade arc, but the origin of its voluminous dacites remains controversial. These dacites were traditionally interpreted as a result of… read more here.

DOI: 10.1007/s11258-018-0849-8
Abstract: We examine patterns of vegetative change in blown-down and scorched forests in the blast zone of Mount St. Helens (USA), 10–26 years after the eruption. We compare trends in community attributes in four post-eruption environments, or… read more here.

DOI: 10.1007/s11629-018-4869-6
Abstract: Long-term analyses of vegetation succession after catastrophic events are of high interest for an improved understanding of succession dynamics. However, in many studies such analyses were restricted to plot-based measurements. Contrarily, spatially continuous observations of… read more here.

DOI: 10.1016/j.epsl.2017.11.010
Abstract: Abstract Rhyodacitic volcanoes such as Mount St. Helens (MSH), Soufriere Hills, Mount Unzen and Mount Pelee erupt spines mantled by layers of magma-derived cataclasite and fault gouge. MSH produced seven lava spines from 2004–2008 composed… read more here.

DOI: 10.1785/0220240079
Abstract: An increase in seismic activity precedes most volcanic eruptions. Whereas event-based forecasting approaches have been successful, some eruptions remain unanticipated, resulting in casualties and damage. Our study leverages the recent advancements in ambient field seismology.… read more here.
