The left sound channel is horizontal acceleration. The right: vertical. The video shows the vertical and horizontal axes correctly.
The video runs at 12 times real time speed.
This is a magnitude 5.1, 16km deep, earthquake, 10 km north-east of Kaikoura
It was recorded about 193km distant in Kapiti, New Zealand.
The S wave arrives about 30.5 seconds after the P wave.
193km / 30.5 seconds = 6.3km per second of PS difference.
The velocity seems low and the waveforms are unusual so this is perhaps a complex event.
Turn it up.
