(CNN) -- A trio of earthquakes struck in the South Pacific Ocean Tuesday morning southeast of Raoul Island, New Zealand, the U.S. Geological Survey said.
There were no immediate reports of damage.
Two quakes, with magnitudes of 6.9 and 6.3, hit within minutes of each other, according to USGS data. The larger of the two was originally reported by the USGS to be a 7.2-magnitude, but that measure was later downgraded to 6.9.
A third, 6.2-magnitude quake struck about 45 minutes later.
The quakes hit near the eastern edge of the Australian tectonic plate, one of the most active seismic regions in the world, according to the USGS.
The quakes all a depth of about 12 miles, and happened about 50 miles southeast of Raoul Island.
