And as she was recording an interview, she found herself capturing a major tragedy - an earthquake that killed over 69,000 people in Sichuan province.

BLOCK: As we're standing here, birds are flying. The ground is undulating under my feet.
FLANAGAN: I've lived in San Francisco all my life. I've been in earthquakes. I was in Loma Prieta. And the ability to stay focused and measured was just astounding. However many years later, I still say to people, did you hear that report on NPR?
