1755_Meknes_earthquake

The 1755 Meknes earthquake affected Morocco on 27 November 1755. The earthquake had a moment magnitude (Mw ) estimated at between 6.5 and 7.0. It devastated the cities of Fes and Meknes—killing at least 15,000 people in both cities. The earthquake struck less than a month after another earthquake that devastated Morocco and Lisbon on 1 November. Previously regarded as an aftershock, this earthquake likely represented rupture of a separate fault due to changes in tectonic stress following their first event.
