This just in: just had the weirdest experience. We felt the earthquake, centred near Chengdu, all the way over here in Xi'an. People poured from buildings after being rocked for only about a minute, with small pieces of debris falling down momentarily. After waiting around outside for an hour or so, we've now begun going back inside.
Reports indicate it was a 7.8 magnitude quake, 57 miles northwest of Chengdu, Sichuan, and was felt in Beijing, Bangkok, Thailand and Hanoi, Vietnam. No reports of damage or casualties yet, but it's very early.
