  1. Data→Information→KnowledgeScientific and educational outcomes of investment in GeoNet John Townend Earthquake Commission Fellow in Seismic Studies Victoria University of Wellington

  2. Key outcomes • Science • New phenomena • Better resolution • Better preparedness • Human capital • Graduate students • Professionals • Leveraged funding • RSNZ, PRBF, NSF

  3. Subductionprocesses Wallace et al., 2010, Eos On timescales of years to decades, much of the plate boundary seems to be locked This highlights areas expected to rupture in future large earthquakes

  4. Wallace & Beavan, 2010, JGR Subductionprocesses On timescales of weeks to months, patches of the plate boundary fault slip in slow earthquakes These and other esoteric phenomena have only been identified with the advent of GeoNet Fry et al., 2011, GRL

  5. GeoNet+ Henrys et al., in prep. Investment in GeoNet has been very highly leveraged, via collaborative research projects involving funding and equipment from New Zealand and overseas

  6. New methods Mid-crust We can measure the speeds at which waves of different pitches propagate and construct images of Earth’s subsurface structure Seismic wavespeed (km/s) Lin et al., 2006, GJI

  7. New methods Mid-crust We can measure the speeds at which waves of different pitches propagate and construct images of Earth’s subsurface structure Seismic wavespeed (km/s) Lin et al., 2006, GJI

  8. Sutherland et al., 2012, Geology Wech et al., 2012, GRL

  10. Key outcomes • Science • New phenomena • Better resolution • Better preparedness • Human capital • Graduate students • Professionals • Leveraged funding • RSNZ, PRBF, NSF

  11. Current challenges • Challenges • Lots and lots and lots of data • Small numbers of incoming students • A difficult funding situation for tectonic/seismological research in universities

  12. Opportunities • Making more extensive use of waveforms • Including S-picks in hypocentre calculations • Incorporating pick information in CWB records • Making automated first-motion polarity measurements • Looking backwards as we go forwards • Systematising earthquake magnitude calculations • Facilitating access to response information • Ensuring all metadata are complete, accessible

  13. Thinking big What are the infrastructural and organisational requirements of an earthquake early warning system in New Zealand, and what could we do with 10-100 s?
