Suva: A 5.4 magnitude earthquake jolted south of the Fiji Islands about 7.30am (AEST) on Wednesday, less than a day after a stronger quake rocked the Pacific Island nation.
There were no reports of damage and no tsunami warning was issued.
Earlier on Sunday a massive earthquake of 5.9 magnitude struck off the Mexican west coast, the Pacific Tsunami Warning Center said.
The epicentre of the quake was 99 km south-southwest of Tonala, in Chiapas State.
Earlier, Mexico’s capital was shattered by a magnitude 7.1 quake on Tuesday that flattened dozens of buildings and killed at least 307 people.
Another magnitude 6.2 earthquake shook southern Mexico on Saturday and was felt in the capital, where seismic alarms sounded.
