Seismologist says two quakes responsible for major damage

By Heeni Brown

GNS seismologist Dr. Jason Ristau says today's earthquakes are some of the biggest to hit NZ in a long time.  Dr. Ristau says there were two significant earthquakes which came to a magnitude of around 7.5 with a reverse-faulting earthquake occurring south of Kaikoura causing a lift to one side of the ground and a strike-faulting event in the north near Seddon causing two areas of land to go past one another.
