Jessica Allen is a PhD student at the University of Otago in Dunedin, New Zealand. She works under the supervision of Ting Wang and Mark Bebbington applying statistical methods to seismological contexts, with a particular focus on problems regarding event detection and unobservable processes.

The research she presented at EGU23 explores the recurrence of low frequency earthquakes (LFEs) recorded along the San Andreas Fault using hidden Markov models and clustering methods. These techniques reveal additional details regarding the occurrence patterns and properties of LFEs, and findings support the development of methods for the more challenging detection and modelling of associated slow slip events. During this research Jessica was supported by a Fanny Evans scholarship.

Jessica is now working on the detection of seismic swarms in the Hikurangi subduction zone of New Zealand using 3 dimensional hidden Markov models and Epidemic Type Aftershock Sequence models. This is part of a larger project funded by an MBIE Smart Ideas grant to forecast future megaquakes in New Zealand. She also receives a University of Otago PhD scholarship.
