I grew up in Southern California and experienced many a earthquake including the Northridge earthquake which was memorable. Though many in many area felt the recent East Coast earthquake, it went unnoticed at my house. I think it was because we were all in the basement so we did not feel our house move at all. Still, this is a teachable moment for any child who might have anxiety or curiosity about earthquakes between this one and the huge one in Japan. I found these links from a variety of articles and hope you find them useful!
