First time for me too! My office chair began moving and it felt weird. I know it’s on wheels, but it was moving and I wasn’t. Then the window treatments were moving and I thought it’s a breeze. Then the foundation of the building was shaking–and only then it occurred to me that this might be an earthquake! Just as soon as I realized what’s going on, the quake stopped. Thankfully nothing happened and I hope that no one else who experienced this sustained any injuries or damage.
Whew… I’m relieved!!
