7.9 is just a number and doesn't mean much until you put it in perspective. The Recent earthquakes map for CA & NV doesn't go to 8 and the biggest we've had lately is a 4.3 off the coast. I suspect that if a 7.9 hit SOCAL that website would go offline -- 7.9 is fraking huge. The death toll in China is going to be high (but won't approach the death toll in Myanmar from that Cyclone they should have seen coming) and a kit isn't much use if you die in the initial moments. Afterward, if you can find your kit, it's time to start working, no time for bugging out.
