The US Geological survey says a magnitude 5.8 quake struck Samoa this morning.
It says the quake which happened after 9am local time was 257 kilometres southwest of Apia at a depth of 39 km.
A tsunami watch was issued following the quake but that has now been cancelled.
Our correspondent Autagavaia Tipi Autagavaia says the earthquake was strong but short, following which the Met Office issued a tsunami watch.
"But just after forty minutes of that tsunami watch from the Met Office it was cancelled so everything is back to normal. But some of the schools in town are now closed. Parents are being informed by the teachers to come and pick up their kids from schools because they are closed, even though it's been cancelled, the tsunami watch."
Autagavaia Tipi Autagavaia says there are no obvious signs of damage from the quake.
The quake was also felt in neighbouring American Samoa.
In September 2008, Samoa, American Samoa and Tonga were hit by a 8.1 magnitude earthquake and tsunami, which killed 186 people.
