This came less than a week after the country was shaken by a 6.4 magnitude earthquake.
Wednesday’s quake was located north of the Paria Peninsula and occurred at around 7.19 a.m.
It had a depth of 64 kilometres and was 10.89 degrees north, 62.21 degrees west.
There were no reports of injuries or damage.
On Friday night, the 6.4 magnitude earthquake, which also rattled Grenada, St Vincent and the Grenadines and Guyana, forced electricity cuts in several areas.
The quake was the most powerful felt in Trinidad and Tobago since 1997 when an earthquake with a magnitude of 6.1 struck, causing damage in Tobago.
