Earthquake occurrence date: 2021-03-04
Depth of earthquake: 16.00 km
*Model was calculated at the date of forecasting
Figure 2: M7.3 Off E. Coast of N. Island (NZ) earthquake – shear-traction field at the near-, intermediate- and far- field distances from the earthquake.
The M7.3 earthquake east of New Zealand was triggered by a local increase of the shear-traction field which was elevated due to the passing of tectonic waves through the region.
On February 4th, we forecasted the elevated possibility for earthquakes in the region of the Eastern Coast of N. Island in New Zealand for the time period from 2nd March 2021 to 8th March 2021. The strongest one happened on 4th March and was followed by several more in the following days.
As shown on Figure 2, the passing of tectonic waves increased both near- and intermediate- shear-traction field and in turn, triggered the earthquake.
