SUMMARY

A significant earthquake occurred offshore of the lower west coast of the North Island of New Zealand, with a depth of approximately 37 km. Reports of the quake were felt across New Zealand, with no injuries reported. The USGS confirmed a magnitude of 5.6 for an aftershock located 29 km WNW of Foxton, New Zealand, at a depth of 51.9 km. Additionally, a magnitude 5.0 quake was recorded 27 km W of Foxton at a depth of 54.1 km.

PREREQUISITES
  • Understanding of seismic activity and earthquake measurement scales
  • Familiarity with geological concepts such as Earth's crust thickness
  • Knowledge of earthquake reporting tools like GeoNet and USGS
  • Basic comprehension of geographic coordinates and their significance in locating seismic events
NEXT STEPS
  • Research the geological characteristics of New Zealand's tectonic plates
  • Learn about the methods used by USGS for earthquake magnitude assessment
  • Explore the implications of crust thickness on earthquake intensity
  • Investigate the historical seismic activity in the Foxton region of New Zealand
USEFUL FOR

Seismologists, geologists, emergency response teams, and anyone interested in understanding seismic events in New Zealand.

No injuries so far?
 
The quake was about 37 +/- 4 km deep according to the source you linked. The average thickness of the Earth's crust is 35 km, says Wikipedia. In a documentary about NZ I've heard today that Earth's crust is especially thin around NZ.

Hence my question: Was this a mantle quake?
 


Was quite a shake!
