The earthquake occurred at a depth of 56.7 km and the NSW Pacific Tsunami Warning Center have said that there is no threat of a tsunami as sea-level readings from the nearest two deep ocean dart gauges confirm only small tsunami waves were generated.

The earthquake was recorded at seismic stations worldwide, including stations of the Irish National Seismic Network (INSN), see seismic waveforms below (select figure to enlarge).
