A very strong earthquake registered by the USGS as M6.9 hit Kermadec Islands, New Zealand at 06:41 UTC on March 4, 2023. The agency is reporting a depth of 205.7 km (128 miles). EMSC is reporting M6.9 at a depth of 150 km (93 miles).
The epicenter was located 927.4 km (576.3 miles) NE of Ngunguru, Northland, New Zealand.
Based on all available data, there is no tsunami threat from this earthquake, PTWC said.
The USGS issued a Green alert for shaking-related fatalities and economic losses. There is a low likelihood of casualties and damage.
Overall, the population in this region resides in structures that are highly resistant to earthquake shaking, though some vulnerable structures exist. The predominant vulnerable building types are reinforced masonry and unreinforced brick with timber floor construction.
