New evidence of historic earthquakes under central New Zealand has received widespread media coverage this week.
The two earthquakes took place within the last 1000 years, and one was accompanied by a tsunami, according to the study published in the Bulletin of the Seimological Society of America (BSSA).
The study, led by GNS Science researchers, analysed sediment cores from a salt marsh near Blenheim, detecting evidence of two strong subduction earthquakes generated by the Hikurangi margin, where the Pacific and Australian plates meet off the east coast of the North Island.
The research has been widely covered in New Zealand. Examples include:
