Μέτριος σεισμός μεγέθους 5.0 - Coral Sea, 68 km νοτιοδυτικά από Isangel, Βανουάτου, Πέμπτη, 25 Αυγ 2022 02:33 (GMT +11) -

An earthquake of magnitude 4.9 occurred only 17 minutes ago 44 km southwest of Isangel, Vanuatu, the German Research Centre for Geosciences (GFZ) reported.
The quake hit at a shallow depth of 10 km beneath the epicenter near Isangel, Tafea Province, Vanuatu, early morning on Thursday, August 25th, 2022, at 2:33 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 the European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 4.9 earthquake as well. A third agency, the citizen-seismograph network of RaspberryShake, reported the same quake at magnitude 4.9.
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 Isangel (pop. 1,400) located 44 km from the epicenter.

Based on its magnitude, the fault that was active during the quake ruptured along a surface of approx. 10 km² (=4 sqare miles) as a first-order estimate. The length of the rupture zone thus was probably around 5 km (3 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).
