A 2.4-magnitude earthquake struck the South Island Monday night, with many residents taking to Twitter to report shaking in their area.

The U.S. Geological Service reported the shaker struck just after 7 p.m., about six kilometres southwest of Langford at a depth of 21.8 kilometres.

It was first reported as a 1.9-magnitude earthquake, but the USGS later upgraded it to a 2.4-magnitude.

Multiple people reported feeling a light rumble on the West Shore, Sooke and Victoria.

Others said the tremor shook their entire house.
