Seismological Aspects of December 31, 2018, Cairo-Suez Event.

On 31 December 2018 at 10:36:34 UTC shallow earthquake of ML=4.3 took place 25 Km east of Cairo and in the vicinity of the under-construction new Capital city of Egypt (Fig.1). The event was interesting as it was felt with intensity IV up to 50 Km epicentral distance with relatively small magnitude Mw=3.8. the focal mechanism of the event showed Normal faulting with a slight component of strike-slip movement which is in good agreement with the tectonic regime of the area and estimated source parameters are found to be in agreement with intraplate earthquakes. These results could support that the event is triggered by the Pre-Tertiary E-W faults as an on land continuation of the Gulf of Suez extensional process.
