Fiji earthquake: Two earthquakes hit between Fiji and New Zealand without tsunami warning
At about 8:03 am, a magnitude 6.5 earthquake occurred 333 kilometers from New Zealand. The depth of the earthquake was recorded 337 kilometers below sea level.
Shortly after the first earthquake, the second earthquake was registered as 6.1. The Australian Meteorological Agency confirmed that these earthquake events did not produce tsunamis.
The depth of the first earthquake may have played a role in mitigating the risk of tsunamis. Deeper earthquakes are less likely to produce tsunamis than shallower earthquakes of similar size. This is because deeper earthquakes replace less water on the ground, reducing the potential for large waves.
Fiji and New Zealand are located in Kmadigou. This trench is a deep-sea depression extending from New Zealand to Fiji.
The Kmadi Gulcan is the main geological feature of the region. This is a deep sea trench that extends from New Zealand to Fiji. The ditch is famous for its seismic activity, which is known for the tectonic plate movement in the region. The Pacific plate brackets below the Australian plate form a huge pressure and frequent earthquake zone. The depth of the first earthquake 337 kilometers below sea level places it within this subduction zone. This depth suggests that earthquakes originate from the interactions of these tectonic plates. The second earthquake, although not specified in depth, may occur in the same tectonic environment.
The Kmardi Grooves are part of the Pacific Ring of Fire, which is the high volcanic and seismic activity around the Pacific Ocean.
