Why mapping marine or lacustrine terraces?

tracking sea-level changes and deformation..

Marine terraces have been used since years to estimate paleo-sea-level positions and the amount of uplift experienced since their formation. Indeed, marine terraces are valuable trackers of crustal deformation along coastal areas, the information obtained from marine terraces is crucial for the understanding of seismo-tectonic segmentation, earthquake recurrence and mechanisms of crustal deformation along active coastal areas. Likewise, lacustrine terraces, formed by similar process as marine terraces have been used to study local paleoclimatic variations and deformation in continental interiors.  The study of marine terraces as benchmarks of tectonic deformation has provided first order information for adequate earthquake hazard assesments along highly-populated active coastal areas around the world ...
