Weirdly didn't feel that one as I was downstairs! My flatmates upstairs felt it tho! (The house is weird like that)

Hubs, MIL and I were sitting around her table having dinner. Hubs was the only one who felt it - but it was faint enough that he wasn't sure until he saw the alert on his phone.

R did feel it downstairs, whereas I was standing (in the middle of leaning down to a lower shelf to grab a cookbook) when it happened, so it was more that weird wobble through your brain sensation before the crockery and glasses started chattering.
