Moderate magnitude 4.8 earthquake 13 km southeast of Orkney, South Africa

4.8 quake 17 Jul 11:19 am (GMT +2)
4.8 quake 17 Jul 11:19 am (GMT +2)
A shallow magnitude 4.8 earthquake was reported in the morning near Orkney, Dr Kenneth Kaunda District Municipality, North West, South Africa.
According to the United States Geological Survey, the quake hit on Sunday, July 17th, 2022, at 11:19 am local time at a shallow depth of 10 km. Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. 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 4.8 earthquake as well. A third agency, the citizen-seismograph network of RaspberryShake, reported the same quake at magnitude 4.8.
Based on the preliminary seismic data, the quake was probably felt by many people in the area of the epicenter. It should not have caused significant damage, other than objects falling from shelves, broken windows, etc.
In Orkney (pop. 145,800) located 13 km from the epicenter, Stilfontein (pop. 93,100) 18 km away, Klerksdorp (pop. 178,900) 21 km away, and Viljoenskroon (pop. 55,000) 27 km away, the quake should have been felt as light shaking.
Weak shaking might have been felt in Potchefstroom (pop. 123,700) located 44 km from the epicenter, and Bothaville (pop. 71,900) 46 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.
