Egypt records 5.77-magnitude earthquake 412 km north of Marsa Matruh
Egypt records 5.77-magnitude earthquake 412 km north of Marsa Matruh; light shaking felt, no casualties reported. A 5.95 quake also struck Crete. Authorities.
A 5.77-magnitude earthquake was recorded early Friday by Egypt’s National Institute of Astronomy and Geophysics, the agency said, with an epicenter located 412 kilometres north of the Mediterranean city of Marsa Matruh. The quake, which the institute identified as measuring 5.77 on the Richter scale, was detected at 05:18 local time and was felt lightly in some coastal areas. Officials reported no fatalities or damage in initial assessments while monitoring for any subsequent activity. The event occurred amid a day in which neighbouring parts of the eastern Mediterranean also experienced seismic activity.
National institute records 5.77-magnitude quake north of Marsa Matruh
The National Institute of Astronomy and Geophysics announced the earthquake after its national seismic network captured the ground motion, providing coordinates that place the epicentre far offshore in the central Mediterranean. Instruments indicated the tremor had moderate magnitude but occurred well beneath the sea at a measurable depth. The institute immediately circulated its technical parameters to relevant civil protection units and international monitoring bodies. Those readings form the basis for the agency’s preliminary assessment that impact on land would be limited.
Timing, depth and seismic details reported by the institute
Seismographs registered the event at 05:18 a.m. local time, corresponding to 02:18 GMT, and calculated a focal depth of roughly 26.85 kilometres. That depth suggests the rupture occurred within the upper crust, a depth range commonly associated with perceptible shaking but variable surface effects depending on distance and crustal properties. The institute’s recorded coordinates place the epicentre around 412 kilometres north of Marsa Matruh, well offshore yet close enough for coastal tremors to be felt in nearby communities. Emergency services confirmed they were reviewing sensor data and readying rapid assessments for any late-arriving reports.
No casualties reported; residents felt light shaking in coastal localities
Initial messages received by the institute and local authorities indicated reports of light shaking from residents but no injuries or structural damage were reported in the immediate aftermath. Coastal towns in northwest Egypt recorded brief perceptible motion, and social media posts from the wider region described short-lived tremors. Local civil defence units conducted rapid checks of critical infrastructure and public facilities and found no signs of significant impact. Authorities urged calm while continuing door-to-door checks in vulnerable localities and monitoring for any delayed reports.
German research centre notes a 5.95 quake on Crete the same day
Separately, the German Research Centre for Geosciences (GFZ) reported an earthquake measuring 5.95 that struck the island of Crete earlier in the day, underscoring broader seismic unrest in the eastern Mediterranean. GFZ and other international seismological agencies routinely share data, and the temporal proximity of the two events prompted experts to examine whether they are independent strikes or part of clustered activity in the regional tectonic system. While simultaneous quakes in the Mediterranean can occur without direct linkage, the coincidence increases the focus of regional monitoring networks. Greek authorities have not reported major damage in connection with the Crete event in preliminary communications.
Regional seismic context and historical patterns in the eastern Mediterranean
The eastern Mediterranean lies along complex plate boundaries and fault systems that periodically generate moderate to strong earthquakes, some of which have historically caused significant damage. Offshore seismicity is common and can produce felt events onshore depending on magnitude, depth and distance, as well as local soil and building conditions. Seismologists note that many Mediterranean quakes originate from interactions between the African, Eurasian and Anatolian plates, producing activity across a wide swath that includes southern Greece, western Turkey and the North African coast. Continuous monitoring and historical catalogues help authorities contextualise individual events and estimate aftershock probabilities.
Monitoring agencies issue guidance and maintain heightened surveillance
Following the detection, national and regional monitoring agencies intensified observation of seismic networks and issued standard public guidance advising residents to check for damage, secure heavy objects and follow updates from official channels. Civil defence teams remain on alert to respond to any reported impacts and to provide assistance where needed. Scientists will analyse waveform data during the coming hours and days to refine the event’s parameters and to track any aftershocks. Authorities emphasised that while the initial assessment shows no casualties, continued vigilance is important until the sequence of activity stabilises.
The sequence of events on Friday underscores the importance of robust seismic monitoring and public preparedness in the eastern Mediterranean region, where offshore earthquakes can be felt across international borders. Emergency services and scientific institutions have signalled readiness to manage any unfolding developments, and residents in coastal and nearby inland areas are being urged to heed official guidance and report any damage or unusual observations to local authorities.
