The Vanatau plot is interesting as the car driving-in signal is on 
the trace and swamps the quake signal. so you can get some idea of 
what the trace looks like in relation to the car. You can also see on 
the bottom, or vertical signal how the car depressed the garage floor 
(trace moves upward and then settled back down).

Interesting
