Seismic waves visualized.

Great (except for the ‘music’, so be sure to mute it) video showing the different waves you see around any given earthquake.
It illustrates beautifully why it’s not always ‘clear’ just what waves you are seeing after a biggish quake from just one station.
This is why I am glad to be part of the bigger network of seismographs.
My data can contribute to the greater bucket of data and thus be part of reducing the noise and extracting the signal.
