The 2019 Outstanding Student Poster and PICO (OSPP) Award is awarded to Tom Winder for the poster/PICO entitled:
The importance of pre-existing structures and stresses to dike-induced earthquakes: The 2014-15 Bárðarbunga-Holuhraun rifting event, Iceland (Winder, T.; Woods, J.; Ágústsdóttir, T.; White, R. S.; Brandsdóttir, B.)

Tom Winder is a PhD student at the Department of Earth Sciences, University of Cambridge, UK. He is studying volcanically and tectonically induced seismicity in the Northern Volcanic Zone of Iceland, particularly focussing on microearthquakes related to the 2014-15 Bárðarbunga-Holuhraun dike intrusion, eruption and caldera collapse.
The poster presented at the EGU General Assembly 2019 shows some of the research Tom has carried during his Masters & PhD projects in collaboration with Dr. Jennifer Woods and Dr. Thorbjörg Ágústsdóttir, under the supervision of Prof. Robert S. White. This research combines the work presented in Woods et al. (2019) and Ágústsdóttir et al. (2019) on extremely high-resolution observations of the seismicity triggered along the path of the 2014 Bárðarbunga-Holuhraun dike intrusion. Carefully analysing the spatial distribution and mechanism of these microearthquakes provides new insight into the controls on the spatial occurrence and mechanism of dike-induced seismicity; these new lessons are compared to observations made during several other dike intrusion events around the globe.
