Dr Andy Nowacki

Profile

I am a seismologist interested in global and local seismic phenomena which allow us to understand better how the Earth works, including how the interior of the Earth moves around, where and how molten material is created, how to produce sustainable power, and the history of our planet.

My experience includes the observation and modelling of the effects of seismic anisotropy—the variation of properties with direction—to infer deformation, encompassing mineral physics, seismic wave propagation and geodynamics. I am also interested in microseismicity in various places (e.g., Ethiopia, the UK, Iceland) and settings (volcanic, geothermal), and how earthquakes occur in the Earth's transition zone.

I am currently a Lecturer in Geophsics, and I am also an associate within ‘COMET’.

Employment history

• Lecturer, University of Leeds (2018–)
• Leverhulme Early Career Fellow (2015–2018)
• Postdoctoral Research Assistant, University of Bristol (2012–2015)
• PhD, University of Bristol (2008–2012)

Current projects

• MC²: Mantle circulation constrained.

Past projects

• REMIS: Reliable Earthquake Magnitudes for Induced Seismicity. In collaboration with Andrew Curtis, Brian Baptie and Corinna Roy.

Postdoctoral researchers

I currently advise Jamie Ward on the project ‘MC²’.

Future projects

I am currently interested in supervising PhD projects in the areas of:

• Global seismic observations and modelling of mantle flow and deep mantle processes
• Automated microseismic event detection and location, including with machine learning apporaches
• Transition zone observation and modelling
• Volcanic and geothermal reservoir imaging, especially using seismic anisotropy and seismicity
• Fibre-optic seismic sensing, using for example distributed acoustic sensing

Current PhD students

• Andrew Pretorius – Machine learning and fibre-optic sensing of seismic signals in glaciers (co-supervising with Adam Booth, Sjoerd de Ridder, Emma C Smith)
• Bolin Li (co-supervising with Sjoerd de Ridder)

Past PhD students

• Itahisa González Álvarez (2022) – “Bayesian modelling of seismic scattering and intrinsic attenuation in the lithosphere” (co-supervising with Sebastian Rost and Neil Selby)
• Jamie Ward (2021) – “Analysis of Mantle Heterogeneity through Array Observations of Multipathing and its Expansion to a Global Scale” (primary supervisor with Sebastian Rost)
• Emmanouil Parastatidis (2019) – “How do seismic waves respond to fractures in rock? Evaluation of effective media versus discrete fracture representations” (co-supervisor with Mark Hildyard)
• Peidong Shi (2018) – “Microseismic full waveform modeling and location.” (primary supervisor with Sebastian Rost and Doug Angus)

Software

I maintain various software packages (mostly written in Julia) for dealing with seismic data and modelling.  These are available at my GitHub page.
