New Zealand Geophysics Prize

2019 New Zealand Geophysics Prize winner:
Emily Warren-Smith

 

The publication in ‘Nature Geoscience’ is the culmination of dedicated, detailed study of earthquake focal mechanisms and subsequent stress calculations.  It draws, in particular, on Emily’s experience making detailed seismological observations in other tectonic regions of New Zealand. 

Such work required careful analysis to reduce uncertainty and reliably discern subtle signals in the complex data.  The signals that Emily and her co-authors document have emerged from the data following diligent work, by Emily in particular, relocating and analysing earthquakes using world-class data from on-land and ocean-bottom seismographs. 

The insightful and creative interpretations drawn from this unique dataset have far-reaching implications for the role of fluid and stress cycling in slow-slip events, and raise the tantalising possibility of observing premonitory changes before large earthquakes.

The New Zealand Geophysics Prize

The New Zealand Geophysics Prize is the Society’s top geophysical award, and was set up by the New Zealand Geophysical Society.  It is bestowed upon the author or authors of the most meritorious eligible publication in the field of geophysics.

The publication shall describe research in the field of geophysics that has been either carried out in New Zealand, or carried out principally by a New Zealander, temporarily overseas, or pertains to the New Zealand region, published in the current or previous two calendar years.
