5.3 earthquake Sep 27 00:58 (GMT +11)

A 5.3 magnitude earthquake near Santo, Luganville, Sanma Province, Vanuatu, was reported just 17 minutes ago by the Euro-Mediterranean Seismological Center (EMSC), considered one of the leading international agencies who monitor seismic activity around the world. The earthquake occurred at a shallow depth of 15 km below the epicenter after midnight on Tuesday, September 27, 2022, at 00:58 local time. The exact magnitude, epicenter and depth of the quake could be revised in the coming hours or minutes as seismologists review the data and refine their calculations, or as other agencies release their report.
A second report was later released by the RaspberryShake Citizen Seismograph Network, which also listed it as a magnitude 5.3 earthquake. A third agency, the German Research Center for Geosciences (GFZ), reported the same magnitude 5.3 earthquake.
Based on preliminary seismic data, the quake should not have caused significant damage, but was likely felt by many people as a slight vibration in the epicenter area.
Weak tremors could have been felt at Santo (pop. 13,400) located 103 km from the epicenter, Norsup (pop. 3,000) at 106 km, Lakatoro (pop. 710) at 108 km and Port-Olry (pop. 2,000) 120 kilometers away.

Data for the same earthquake reported by different agencies

Info: The more agencies report the same earthquake and publish similar data, the more confidence you can have in the data. It normally takes up to a few hours for the seismic parameters to be calculated with near optimum accuracy.
