A week after a flurry of significant seismic activity offshore west of Vancouver Island, a moderate earthquake has occurred in the same area.
According to the U.S. Geological Survey, a 4.0-magnitude quake struck in the Pacific Ocean at 4:24 p.m. local time on October 28 with an epicentre located 144 kilometres (89 miles) west of Tofino at a depth of 10 kilometres (6 miles).
It was 228 kilometres (140) miles) west of Port Alberni and 338 kilometres (210 miles) west of Victoria.
Last week on October 21 and 22, a series of seven quakes occurred, ranging from 4.3- to 6.8-magnitude.
An eighth quake, measuring 4.0-magnitude took place at 5:07 p.m. local time on October 23 with an epicentre 264 kilometres (164 miles) west of Tofino at a depth of 10 kilometres (6 miles).
