We have enclosed the seismogram of this earthquake to give you an idea of the travel time of the wave in the earth. We monitor tens of stations all around the globe and the Chiang Mai, Thailand station was the closest we could find. The signal arrived in Chiang Mai roughly 4 minutes after the earthquake struck and traveled a distance of 1850 km.
The magnitude of the Papua New Guinea quake was 6.4, a lot stronger, but because of the greater distance, the markings on the seismogram in Chiang Mai are smaller.
