A Journey Through Fractures: From New Zealand's Alpine 

Fault to White Island Volcano

Rock fractures control subsurface fluid flow, decrease rock strength and -- during their formation -- are the source of seismicity. Chemical reactions made possible by the fluids in the fractures can lead to mineral precipitation and rock dissolution, for example, in CO2 geo-sequestration. Understanding the effects of fractures on seismic waves is also critical when imaging and monitoring faults and volcanoes. I’ll present laboratory elastic wave measurements and applications to the field for a range of topics where fractures are central to the story, from New Zealand's Alpine Fault to White Island Volcano. pass code: 840912
