A 2.5-magnitude earthquake struck the West Shore just after 10 p.m. on Tuesday.
The US Geological Survey says it hit at 10:06 p.m., about seven kilometres from Langford at depth of 27.3 kilometres.
CHEK viewers from areas including Colwood, Langford, Metchosin, Central Saanich, Sooke and Sidney all reported hearing or feeling the small quake.
“Quite a rumble and shake,” wrote one viewer.
“Definitely felt it! I thought a car crashed into the house,” tweeted another.
There were no reports of damage and officials do not expect any.
Experts say it was one of around a thousand small earthquakes that happen around Vancouver Island every year, most of which are not felt.
John Cassidy from the Pacific Geoscience Centre says it provides vital data for researchers who are now creating an updated hazard model.
“It’s information that is used by emergency managers for developing earthquake scenarios and for planning response to future earthquakes,” Cassidy said. “What can you expect, and where can resources be deployed most effectively?”
