On Friday afternoon, Egypt was subjected to an earthquake with a magnitude of 5.7 on the Richter scale, according to the stations of the Egyptian National Seismological Network.
The National Institute for Astronomical Research said the tremor occurred at 9:12 minutes and 47 seconds Cairo time, 855 kilometers north of Marsa Matrouh.
The institute noted that the tremor occurred at 37.40 degrees north latitude and 21.50 degrees east longitude and at a depth of 25 km.
The Euro-Mediterranean Seismological Center reported an earthquake measuring 5.7 on the Richter scale in southern Greece, adding that its epicenter is located at a depth of 17 kilometers and 122 kilometers southwest of the Greek city of Patra.
There was no information about injuries or damage from the tremor.
Egypt is far from seismic belts, but close to some seismically active areas such as the Gulf of Aqaba, the Gulf of Suez, and the Red Sea, which makes it vulnerable to some medium-magnitude earthquakes.
