Widespread disruption to long haul aviation services are expected as a series of aftershocks and Tsunami warnings some now downgraded to 'advisory notices' have closed airports. Other airports are sending engineers to check runway surfaces and substrates for damage before allowing aircraft to land or take off. In 2010, an 8.8 magnitude earthquake was experienced.
Local air traffic control report the earthquake has also left some aircraft in the wrong position, and this will have a 'knock on' effect over the next few days possibly weeks .
The earthquake epicentre is some 144 miles off the coast, north-west of the capital.
Earlier the The Pacific Tsunami Warning Centre cautioned "widespread hazardous tsunami waves possible." 15ft waves along the coast are being reported, in the region of Coquimbo.
Tsunami alerts are being posted for Peru, Hawaii, parts of California and as far away as New Zealand, where the authorities warned of unusually strong currents and unpredictable water flows. At least one school so far has been evacuated.
