Collection: An Earthquake Early Warning System for Southwestern British Columbia Enables Detection of Sovanco Fracture Zone Seismic Events in 2018
This collection represents the datasets used in the publication "An Earthquake Early Warning System for southwestern British Columbia" by Schlesinger et al (2021). Ocean Networks Canada (ONC) has developed an Earthquake Early Warning (EEW) system for southwestern British Columbia, Canada. The system successfully utilizes offshore cabled seismic instruments in addition to land-based seismic sensors. While the EEW system was only partially installed and algorithms were still under development, the first successful event detection occurred in late 2018 when a series of seismic events along the Sovanco Fracture Zone was detected. According to the NRCan earthquake catalog, the first earthquake (M6.1) occurred at 05:39:35 (UTC) on October 22nd, 2018. The hypocentre was located 218 km SW off the northern tip of Vancouver Island at a depth of 11 km. The first P-wave from this event was detected on two subsea stations, Clayoquot Slope Bullseye (NC89) and Cascadia Basin (CBC27); eight seconds prior to the first land-based stations detecting the same event (Beaver Cove (BCOV), Tofino (TFNO), Ucluelet (UCLU), Victoria Peak (VICP)). This data collection contains the parametric data used in the EEW system to determine the epicentre and magnitude of an earthquake.
