The Los Angeles County Fire Department says that — based on real-life-experience — the "triangle of life" method of earthquake survival doesn't work.

So to give us some ideas of what does work, the LAFD has released a booklet (available here in PDF form) about surviving earthquakes and other disasters.  

As for what you do during an earthquake: the watchword is "Drop-Cover-Hold On" (with animation to show exactly what you should do).
