I've never experienced one, but we have had two close calls where school was cancelled because of tsunami warnings. Living smack dab in the Pacific Rim is scary because every time we hear of an earthquake in Alaska, Japan, or Chile, we cringe.
My pops lived in Hilo when the massive tsunami killed thousands of people in 1960. He had nightmares about it for years.
I'm so sorry to hear about the devastation in Indonesia.
