All is well, and I think yesterday's event probably has something to do with the episodic slow slip away and sudden slam back again that happens every 14 months between Vancouver Island's separate plate and the BC mainland's plate.
No damage was done to any structures despite the rather violent shaking and concussion waves that occurred this time. Right now (between yesterday and for the next several days) there are engineers doing thorough inspections on all of the bridges in south west BC (there are a lot of bridges) to ensure that their structural integrity has not been compromised due to the loud concussion and the shaking, rocking 'n' rolling that occurred.
After watching news reports last night it would appear that the worst effects that happened was to the many people like myself who were most sensitive to the very loud !! WHUMP !! sound suddenly coming from within the ground (it's a bit like the sound that fire makes when it suddenly explodes only it's 100 times louder) and the concussion waves that cause disorientation and nausea as the concussion waves pass through the soft tissues of the body. But that doesn't last long. So everyone's okay.
