An earthquake of magnitude 4.5 occurred only 11 minutes ago 70 km northeast of San Giovanni Rotondo, Italy, the German Research Centre for Geosciences (GFZ) reported.
The quake hit at a shallow depth of 10 km beneath the epicenter near San Giovanni Rotondo, Provincia di Foggia, Apulia, Italy, early afternoon on Saturday 27 March 2021 at 3:01 pm 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 4.5 earthquake as well. A third agency, the National Observatory of Athens (NOA), reported the same quake at magnitude 4.2.
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 San Menaio (pop. 250) located 43 km from the epicenter, Vico del Gargano (pop. 7,300) 47 km away, and Sannicandro Garganico (pop. 15,800) 61 km away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include San Giovanni Rotondo (pop. 26,200) located 70 km from the epicenter, Manfredonia (pop. 52,900) 77 km away, San Severo (pop. 54,900) 83 km away, Termoli (pop. 31,000) 84 km away, and Torremaggiore (pop. 17,000) 87 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.
