Only one major quake so far, so a second by week's end looks unlikely

As of the latest check against the United States Geological Survey catalogue at 12:03 UTC on September 27, only one earthquake of magnitude 6.5 or higher has been recorded in the window running from September 21 to September 27 Eastern time. That event was a magnitude 6.6 tremor 80 kilometers ENE of Tadine, New Caledonia, which struck on September 25 at 21:23 UTC and was later reviewed and confirmed at that magnitude. With roughly sixteen hours left in the window at the time of that check, a second qualifying earthquake would need to strike in a fairly narrow remaining stretch. Historical patterns cited alongside the catalogue reading suggest such events of this size average about 0.12 per day globally, and that in a typical seven-day span holding one qualifying earthquake, a further one arrived in the final short window only about 7 percent of the time. That combination, one confirmed event and a small residual window, is why the outlook leans firmly toward the total staying at one rather than reaching two. A separate report on September 26 similarly noted just a single qualifying event in the catalogue, reinforcing the reading rather than contradicting it. The one thing that could still shift this is any large earthquake striking somewhere on Earth before the window closes at 11:59 PM ET on September 27. Short of that, the record as it stands points toward the count remaining at one.
