An earthquake of magnitude 5.7 has struck Vanuatu this evening, the European Mediterranean Seismological Centre says.
The EMSC earlier said the magnitude was 6.6.
The quake had a depth of 10km and hit at about 6.29pm (NZT), EMSC said.
It follows a magnitude 6.3 quake that struck off the Pacific island nation on Sunday.
The Australian Bureau of Meterology says the quake is not expected to have tsunami impacts on the country.
