4.3-magnitude quake shakes Inland Empire — EARTHQUAKE

Janie Tyerman, who was at home in Tsawwassen, was sitting in front of the living room fireplace when the room began to sway.

"I just felt the floor kind of sliding back and forth a bit", he said. "The next thing I knew the texts were coming in". Sullivan said she could hear items falling out the medicine cabinet in the bathroom.

TransLink temporarily shut down the Millennium and Expo lines of the SkyTrain, but spokeswoman Anne Drennan said they, along with bus bridges, were reopened for one last run. Service resumed Wednesday morning.

Several people used Twitter to report noticeable shaking and swaying light fixtures, but tremors of that magnitude are typically not considered threatening.

The City of Vancouver used the quake to remind people to be prepared for a large-scale disaster. The widely felt quake caps a record year for earthquakes in Oklahoma.

"It felt like the whole world was bouncy, and it was really shaky".

Tom Eades, a 911 dispatcher with the San Juan County Sheriff's Office in Washington, says the agency received lots of calls but no reports of damage or injuries. YouTube user Darrell Vancouver posted footage of the quake from a security camera in Langley. And it continued, and it got worse and worse.

"They have been shown to produce up to Mag. 5.6 and in a few studies we have done at the USGS, we have shown that some of these faults could host earthquakes as big as Mag 6", said McNamara.

There are now no reports of damage, and none are expected. The quake originated about 52 kilometers below the earth's surface.

He says the 4.3 to 4.8 magnitude quake last night was the strongest to hit the Cascadia subduction zone - the area where coastal B-C earthquakes originate - since a 6.8 quake near Seattle in early 2001.

There was also a separate magnitude 4.4 natural disaster on Sunday near San Bernardino, Calif.

The 4.3 magnitude quake caused about 10 seconds of shaking, about a third as long as a magnitude 7 would generate, according to experts.
