Detections of tremor at a set of template locations over the course of four slow slip events in 2004, 2008, 2009, and 2010. As well as identified bursts of tremor within these windows. The dataset consists of: Detected spikes in the tremor time series Each file contains a list of identified spikes in the inter-component coherence time series. LFE (Low frequency earthquakes) locations The locations of LFEs identified by Bostock, M. G., Royer, A. A., Hearn, E. H., and Peacock, S. M. (2012), Low frequency earthquakes below southern Vancouver Island, Geochem. Geophys. Geosyst., 13, Q11007, doi:10.1029/2012GC004391. Cp values through time 12 files containing time series of inter-component and/or inter-station coherence at a range of LFE locations Further descriptions are available in the README and in the preprint hosted on EarthArxiv: Gombert and Hawthorne, Rapid tremor migration during few minute-long slow earthquakes in Cascadia, 2022, doi: 10.31223/X56623.
