This tremor catalog is a 2019 revision of the tremor catalog from the Pacific Northwest Seismic Network ( with specific focus on the Mendocino Triple Junction region. The time range is 01-01-2015 to 01-01-2018. It contains modifications from the PNSN catalog because: 1) the number of available seismic stations was variable in this spatio-temporal range, and 2) the data quality was occasionally poor because a few stations in this spatio-temporal range experienced analog telemetering issues that resulted in false detections. We attempted to address these two problems in the following catalog, producing a slightly different catalog from the automatically generated PNSN version.
