Strong mag. 5.8 earthquake - North Pacific Ocean, 154 km northeast of Pagan Village, Northern Mariana Islands, on Saturday, Jul 9, 2022 at 9:36 am (GMT +10) -

A magnitude 5.8 earthquake near Agrihan Village, Agrihan Island, Northern Islands, Northern Mariana Islands, was reported only 24 minutes ago by the United States Geological Survey, considered one of the key international agencies that monitor seismic activity worldwide. The earthquake occurred at a shallow depth of 10 km beneath the epicenter in the morning on Saturday, July 9th, 2022, at 9:36 am local time. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
A second report was later issued by Geoscience Australia (GeoAu), which listed it as a magnitude 6.0 earthquake. Other agencies reporting the same quake include France's Réseau National de Surveillance Sismique (RéNaSS) at magnitude 5.9, the citizen-seismograph network of RaspberryShake at magnitude 5.8, the German Research Centre for Geosciences (GFZ) at magnitude 6.0, and the European-Mediterranean Seismological Centre (EMSC) at magnitude 6.2.
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 Agrihan Village (pop. 20) located 138 km from the epicenter.

Based on its magnitude, the fault that was active during the quake ruptured along a surface of approx. 63 km² (=24 sqare miles) as a first-order estimate. The length of the rupture zone thus was probably around 14 km (9 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).
