Moderate mag. 5.4 earthquake - South Pacific Ocean, 144 km east of Nukalofa, Nuku'alofa, Tongatapu, on Monday, Nov 28, 2022 at 10:30 pm (GMT +13) -

Just 17 minutes ago, a 5.5-magnitude earthquake struck near Nukalofa, Nuku'alofa, Tongatapu, Tonga. The tremor was recorded late at night on Monday, November 28th, 2022, at 10:30 pm local time, at an intermediate depth of 90 km below the surface.
The event was filed by the German Research Centre for Geosciences (GFZ), the first seismological agency to report it.
A second report was later issued by the citizen-seismograph network of RaspberryShake, which listed it as a magnitude 5.5 earthquake as well. Other agencies reporting the same quake include France's Réseau National de Surveillance Sismique (RéNaSS) at magnitude 5.5, and the European-Mediterranean Seismological Centre (EMSC) at magnitude 5.4.
Generally quakes of this magnitude are recorded by more than one agency and the results can vary, with subsequent reports that come in after the first one often showing more accuracy.
Based on the preliminary seismic data, the quake should not have caused any significant damage, but was probably felt by many people as light vibration in the area of the epicenter.
Weak shaking might have been felt in 'Ohonua (pop. 1,200) located 58 km from the epicenter, Kolonga (pop. 1,100) 73 km away, Lapaha (pop. 8,000) 77 km away, Nukalofa (pop. 22,400) 86 km away, Nuku'alofa (pop. 22,400) 86 km away, and Haveluloto (pop. 3,400) 87 km away.

Based on its magnitude, the fault that was active during the quake ruptured along a surface of approx. 25 km² (=10 sqare miles) as a first-order estimate. The length of the rupture zone thus was probably around 9 km (5 mi).
Aftershocks typically occur during the days and weeks following the quake at or near the same fault, at distances of up to approx. two times the length of the rupture zone.
The often broadly linear arrangement of aftershock epicenters encompasses the rupture zone of the main shock (check on the map below to verify).
