Mega Earthquake
New Zealand (geologists) have found evidence that a large earthquake hits beneath central New Zealand. A ‘megathrust’ is a very large earthquake that occurs in a subduction zone.
An subduction earthquake is when earthquakes occur on the underside of the upper plate. Where both of the plates meet,rather than meeting within the upper plate.
A group of scientists have found evidence, that two huge earthquakes that ruptured in the southern part of the Hikurangi Margin for the past 1000 years.
The margin marks the collision zones between the pacific also the Australian tectonic plates. This evidence proves that the boundary located under the Cook Strait-Marlborough area, this evidence suggest that a large earthquake could eventually rupture.
Subduction earthquakes have the strength to significantly a lot larger magnitude than upper plate fault ruptures. There could be a massive effect on a larger area, and more likely to trigger tsunami.
