Significant magnitude 5.3 quake hits 103 km east of Santo, Vanuatu after midnight

5.3 quake 27 Sep 12:58 am (GMT +11)
5.3 quake 27 Sep 12:58 am (GMT +11)
A magnitude 5.3 earthquake near Santo, Luganville, Sanma Province, Vanuatu, was reported only 17 minutes ago by the European-Mediterranean Seismological Centre (EMSC), considered one of the key international agencies that monitor seismic activity worldwide. The earthquake occurred at a shallow depth of 15 km beneath the epicenter after midnight on Tuesday, September 27th, 2022, at 12:58 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 citizen-seismograph network of RaspberryShake, which listed it as a magnitude 5.3 earthquake as well. A third agency, the German Research Centre for Geosciences (GFZ), reported the same quake at magnitude 5.3.
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 Santo (pop. 13,400) located 103 km from the epicenter, Norsup (pop. 3,000) 106 km away, Lakatoro (pop. 710) 108 km away, and Port-Olry (pop. 2,000) 120 km away.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available. If you're in the area, please send us your experience through our reporting mechanism, either online or via our mobile app. This will help us provide more first-hand updates to anyone around the globe who wants to know more about this quake.
