Magnitude 5.3 earthquake strikes near Santo, Luganville, Sanma Province, Vanuatu
5.3 quake 20 Nov 9:57 pm (GMT +11)
An earthquake of magnitude 5.3 occurred in the evening on Saturday, November 20th, 2021, at 9:57 pm local time near Santo, Luganville, Sanma Province, Vanuatu, as reported by the German Research Centre for Geosciences (GFZ).
According to preliminary data, the quake was located at an intermediate depth of 123 km. The strength of the earthquake may have been tempered by its relative great depth below the surface, which makes it feel weaker in absolute terms. 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.
Our monitoring service identified a second report from the European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 5.2.
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 48 km from the epicenter, Norsup (pop. 3,000) 52 km away, and Port-Olry (pop. 2,000) 87 km away.
