Wind waves are a major erosive agent on the rocky coast. The physical impact of waves is also important in driving erosion above the splash zone. This occurs through the transferral of energy into the bedrock by the action of wave breaking causing microseismic shaking. In this study we concurrently measure wave energy and resultant microseismic shaking on a macrotidal shore platform at Staithes, North Yorkshire, U.K. It is found that infragravity wave generation is limited when compared to microtidal coasts and where it does occur it is confined to the wave breaking zone. Cliff shaking is broadly correlated to wave energy and strongly linked to tidal stage. The highest energy bands of microseisms were recorded at > 10 Hz, which contrasts to the gravity-frequency bands recorded for wind waves on the platform. It is likely that surf zone processes on the platform are more predictive of seismic shaking than absolute wave energy offshore under the low energy conditions that this field experiment was conducted.
