Evidence of subduction quakes under central NZ – Expert reaction

John Kerr posted in on May 19th, 2015.

Scientists have found, for the first time, direct geological evidence of ‘megathrust‘ subduction quakes occurring under central New Zealand. Subduction earthquakes occur where tectonic plates meet, have the potential to be larger in magnitude than fault ruptures closer to the surface, and are more likely to trigger tsunamis. Analysing sediment cores extracted from a coastal […]
