A magnitude 8.2 earthquake that struck Chile this afternoon is not currently registering any tsunami threat to New Zealand.

'MCDEM has assessed the information with the assistance of scientific advisors and based on current information, the initial assessment is that the earthquake is unlikely to have caused a tsunami that will pose a threat to New Zealand,” says a statement from the Pacific Tsunami Warning Centre.

An 8.2 earthquake has struck off the coast of Chile today.

The US Geological Survey initially reports the quake struck 99 kilometres northwest of the Chilean city of Iquique at 8.46pm (12.46pm NZT).

Aftershocks followed, including a magnitude 6.2 tremor and a 5.5 quake.

There was no serious damage to infrastructure or reports of victims following the massive earthquake, a government representative is reported to have said.

Waves about 2m high are reported to have struck the coast of Northern Chile ahead of a tsunami which is expected to hit Robinson Crusoe island and others in the Juan Fernandez archipelago just before midnight local time.

The Pacific Tsunami Warning Centre issued an alert for all of Latin America's Pacific coast.
