Very cool! The text says that 93% of the Napa area woke up, but the graphs shows 74%. I'm assuming the graph is off?

- vamin 12y agoThe graph is showing how many people are awake. The 93% number reflects the fact that some people were already awake before the quake.
- lingc 12y agoThen according to the graph, 59/85 were awoken from sleep, which is about 71%. 59 awoken = 74 (awake at quake) - 15 (awake before the quake) 85 = 100 - 15 (awake before quake) Maybe they are adjusting for other things that are not shown on the graph.
- vamin 12y agoGood point. I wonder if they are smoothing the data, which would make the peaks less peaky (which brings up another question, what is the time resolution for UP's ability to measure wakefulness?).
- lingc 12y agoNever mind. The graph is showing areas based on 25 mile radius, and the 93% is for the 15 mile radius.
