August 12, 2011 — A small earthquake rumbled the Lower Mainland region of B.C. Thursday evening.

Lower Mainland residents may have been startled awake Thursday night -- but not by their alarm clocks.

A magnitude 3.3 hit the region. On a good note, it wasn't entirely earth shattering.

The United States Geological Survey (USGS) said the trembler was recorded at 11:02 p.m. Thursday night. A few people in Maple Ridge, Port Moody -- and others in Coquitlam and Port Coquitlam reported a rocking sensation.

The USGS said the quake was centred in Golden Ears Provincial Park, 59 km northeast of Vancouver.

It occurred at a depth of 4.6 km. It was not strong enough to cause any damage or injury.

Earthquakes in the region are not an uncommon event. Just recently, the Nature Geoscience published a new study that says the fault line in the Pacific Northwest is about seven kilometres deeper than previously thought.

Experts say the greater depth could mean more ground shaking and tremors for urban areas about 100 km inland.
