Dozens of aftershocks after strong NZ quake that triggered tsunami warnings

Saturday, March 6th 2021, 8:20 pm - Thursday's Magnitude 8.1 tremor in the Kermadec Islands sent thousands of New Zealanders scrambling indoors.

Just days after a strong quake caused a tsunami scare in New Zealand, the region's seismic activity continues to rattle the region.

The island nation issued a tsunami warning Thursday after a Magnitude 8.1 earthquake struck the Kermadec Islands, a mostly uninhabited New Zealand possession. Because the tremor struck at a relatively shallow depth of 19.4 km, it triggered fears that a tsunami had been generated, prompting tsunami warnings for the parts of the country's North Island facing the quake's epicentre.

Though a small tsunami was generated, it did not cause much in the way of damage, and the warnings were discontinued.

Since then, however, numerous aftershocks have been reported, both in the Kermadec Islands, and closer to the North Island, which also registered a strong quake on Thursday.

Since then, dozens of aftershocks have been reported in the region, some of them quite strong. One reached Magnitude 6.1, and numerous quakes at least Magnitude 5.0 or stronger have been registered by the U.S. Geological Service.

Earthquake risk is a fact of life in New Zealand, which often experiences the tremors. In 2011, a Magnitude 6.2 earthquake struck near the South Island city of Christchurch. At least 185 people were killed, and up to 2,000 were injured.
