Two hosts from NPR’s afternoon show, All Things Considered, were in the Sichuan Province when the recent earthquake struck. Melissa Block and Robert Siegel were in Chengdu, approximately 60 miles from the epicenter. Melissa Block was in the middle of the interview when the earthquake struck. The audio bit of the interview is available here (just below the photo gallery). About 40 seconds into the recording you can hear the building start to shake, she ran outside narrating what she was looking at as she ran. If you listen closely you can hear a gap in the shaking between the P and S waves. Also, note the time when the shaking starts and when she states that the shaking is subsiding, it is well over a minute.
Having never experienced a quake of this magnitude it is quite surreal to hear. And living in the Bay Area it makes me want to check my earthquake kit.
