The seismogram is from the Lamont-Doherty Earth Observatory in Palisades, NY! That's why it shows the earthquake occurring at 6:46 GMT (same as UTC). The quake occurred at 6:34 but the seismic waves had to travel through the interior of the Earth from Chile to New York - it took about 12 minutes!
It was almost 2,5 min. My house moved like a blender. What a fright!
