Unveiling the Hidden Devastation: Ancient Earthquake's Impact Exposed

Researchers from the University of Otago have discovered a previously unknown zone of coastal uplift in Rarangi, Marlborough, using LiDAR mapping and kelp genetics. The study reveals a 1m above sea level uplifted area and a kelp species that went extinct and recolonized following an ancient earthquake, highlighting the lasting impact of seismic activities on coastal landscapes and species. The findings demonstrate the potential for kelp to record geological disturbance events and emphasize the dynamic nature of New Zealand's coastal regions.
