A magnitude-8.1 earthquake strikes off the southern coast of Mexico, causing a tsunami in the region and killing at least two people.

A magnitude-8 earthquake has struck off the southern coast of Mexico, the US Geological Survey (USGS) said, shaking buildings in the capital city.

People in Mexico City ran out into the streets after the quake struck, a witness said.

Its epicentre was 123 kilometres south-west of the town of Pijijiapan, at a depth of 33 kilometres.

The Pacific Tsunami Warning Centre said widespread and hazardous tsunami waves were forecasted for the region.

Authorities in New Zealand are assessing whether the quake could generate a tsunami along the country's coastline.

The Ministry of Civil Defence & Emergency Management and GNS Science said that if a tsunami had been generated it was not likely to arrive in New Zealand for at least 12 hours.

"We will provide a further update as soon as the initial assessment has been completed," it said.

The Australian Government Bureau of Meteorology said there was no tsunami threat to the Australian mainland, island or territories.
