Tom Winder

Tom Winder is a Researcher in the Department of Earth Sciences at the University of Cambridge, focusing on volcano seismology and induced seismicity. His work spans microearthquake detection, waveform cross-correlation, and analysis of seismicity patterns in central Iceland, particularly related to tectonic spreading and volcanic processes.

• Affiliation: Bullard Laboratories, University of Cambridge
• Key Collaborators: Clare Donaldson, Dr. Tim Greenfield, Professor Robert White

Research Highlights:

• Developed the QuakeMigrate Python package for earthquake detection and location, enabling detailed analysis of microseismicity down to M_L ~ -0.5 magnitudes.
• Studied conjugate strike-slip faulting between Askja and Herðubreið volcanoes, revealing unique swarm seismicity patterns without mainshock-aftershock sequences.
• Analyzed dike-induced seismicity during the 2014-15 Bárðarbunga-Holuhraun intrusion and its impact on static stress fields.
• Investigated caldera collapse seismicity (M_W > 5) following Bárðarbunga's subsidence, producing high-resolution images of ring-faulting structures.
• Explored relative seismic velocity changes (dv/v) using coda-wave and ambient noise interferometry, modeling seasonal variations linked to snow/atmospheric load and pore-pressure changes.

Laboratory & Facilities: Operates within the Bullard Laboratories at the University of Cambridge, utilizing advanced analytical instrumentation including scanning electron microscopy, ICP-MS, and X-ray diffractometry.
