A rare, powerful earthquake that struck Morocco late Friday night, killing hundreds of people and damaging historic buildings, was "exceptional", according to an expert. According to latest reports at least 632 people died and 329 were injured in the quake.
Residents of Marrakech, the nearest big city to the epicentre, said some buildings had collapsed in the old city, a UNESCO World Heritage site, and local television showed pictures of a fallen mosque minaret with rubble lying on smashed cars.
Earthquakes are relatively rare in North Africa. Speaking to Moroccan news network 2M TV, Lahcen Mhanni, Head of the Seismic Monitoring and Warning Department at the National Institute of Geophysics, said, "Mountainous regions in general do not produce earthquakes of this size,” he said. "It is the strongest earthquake recorded in the region.”
In 1960, a magnitude 5.8 tremor struck near the Moroccan city of Agadir and caused thousands of deaths. The Agadir quake prompted changes in construction rules in Morocco, but many buildings, especially rural homes, are not built to withstand such tremors.
Shallow quakes more dangerous
The US Geological Survey said the quake had a preliminary magnitude of 6.8 when it hit at 11.11pm (3.11am UAE time), with shaking that lasted several seconds. The US agency reported a magnitude-4.9 aftershock hit 19 minutes later.
The USGS said the epicentre was 18 kilometres below the Earth’s surface, while Morocco’s seismic agency put it at 8 kilometres down. In either case, such shallow quakes are more dangerous.
The epicentre of Friday's tremor was high in the Atlas Mountains, roughly 70 kilometres south of Marrakech. It was also near Toubkal, the highest peak in North Africa and Oukaimeden, a popular Moroccan ski resort.
The quake was felt as far away as Portugal and Algeria, according to the Portuguese Institute for Sea and Atmosphere and Algeria's Civil Defense agency, which oversees emergency response.
