President Michelle Bachelet declared a "state of catastrophe" in affected areas and appealed for calm.
Tsunami warnings have been issued for Hawaii, Australia, New Zealand and Pacific island nations. Alerts were also earlier issued for Antarctica and Central America.
Santiago airport has been closed and all flights cancelled until further notice, airline officials say. Flights are being diverted to Mendoza in Argentina.
