Update: M6.4 earthquake hits the same region at 21:23 UTC
There is something weird happening in the Royalty Islands, an administrative subdivision of New Caledonia in the Pacific ocean.
The strong quakes happened near New Caledonia in the western Pacific where the Australian Plate is colliding with and subducting beneath the Pacific Plate. As explained above, the biggest one was preceded by a couple of M6 foreshocks <30 mins before.
A tsunami warning is currently active. A tsunami was even confirmed by the Australian Bureau of Meteorology, issuing a warning of a threat to Lord Howe Island, which is about 550 kilometers east of Australia’s mainland.

The tsunami warnings have now been cancelled now, about 10 hours after the first quake.
However, there are no tsunami threats for Hawaii, which is too far away.
The swarm started with a M6.0 quake at 12:24 p.m. UTC.
It was followed by a M6.1 at 1:02 p.m. UTC
The M7.7 hit at 1:20 p.m. UTC
The next big M6.1 hit at 4:35 p.m. UTC
And the last M6.1 (until now) stuck at 6:37 p.m. UTC
I think we will soon have another big one in the next hours. This swarm of big quakes isn’t finished yet. Hoprefully it will not end bad, for example with a deadly tsunami!
