Seismic ‘noise’, the background ambient signals recorded by seismic stations around the planet, can be utlised to infer the structure of the deep continents, the 3D architecture of the tectonic plates.  Ocean storms, at incredible distances, also transmit signals to seismic stations on land.  Archive seismic records can hence be used to investigate storms, and possible changes in storm patterns, over recent decades.  This presentation will survey the variety of seismic signals that we record, novel ways of extracting information from those signals and new insights on the continents and oceans that have arisen through making use of these ‘good vibrations’.
