DNA from kelp records major earthquake that hit Otago about 1000 years ago
Kelp clinging to the rocky South Otago coast has shown scientists the destructive power of a magnitude 7-plus earthquake that hit the region about 1000 years ago.

University of Otago biologist Professor Jon Waters said the research showed major historic quakes could "leave a lasting DNA signature" in terms of coastal recolonisation, just as the November 2016, magnitude 7.8, Kaikōura quake had.
