A magnitude 6.4 earthquake was felt off the northern coast of Egypt, sending tremors through the nation’s capital, Cairo, the coastal city of Alexandria, and surrounding areas early Wednesday morning. No injuries or deaths were reported, according to Egyptian officials.

The earthquake was detected at 1:51 a.m. local time, Egypt’s National Research Institute of Astronomy and Geophysics (NRIAG) said.

Despite being roughly 165 kilometers from the Mediterranean coast, Dr. Sherif El-Hady, head of the Seismology Department at NRIAG, explained that Cairo’s “soft clay soil” contributed to tremors being felt in the city, according to a report by Al Ahram Online.

The earthquake’s epicenter was located near the small Greek island of Karpathos, according to the United States Geological Survey (USGS). The island of Crete also experienced the tremor, registering a magnitude 6.3 earthquake.

The last significant earthquake felt in Egypt occurred in 1995, when a powerful magnitude 7.2 quake off the coast of Aqaba, Jordan, struck Egypt’s Sinai Peninsula, killing five people and injuring dozens, according to a report by The Egyptian Today
