Experts say a massive landslide in a remote inlet on BC's central coast caused a shock that was equivalent to a 4.9 magnitude earthquake.
The slide happened on November 28.
It happened near Elliot Creek, just east of the head of Bute Inlet north of Powell River.
Brent Ward, a geology professor and co-director of the Centre for National Hazards Research at Simon Fraser University, says the landslide created its own seismic event.
Local Indigenous groups say the landslide impacted salmon spawning habitat.
