The quake hit the island region at 16:44 UTC and had a depth of 157 kilometers (approximately 97 miles) and was tectonic in origin.
Phivolcs warned the public for possible aftershocks but said no damage is expected.
The Batanes Islands are in the northernmost region of the Philippines and make up the smallest province, in both land area and population.
Last year, a series of earthquakes hit Batanes in the early morning hours of July 27, 2019.
Two quakes—magnitude 5.4 and magnitude 5.9—struck within hours of each other, according to bulletins from Phivolcs. A third quake shook the provincial capital Basco later that morning with a magnitude of 5.8 while a weaker 4.9 tremor was recorded by Phivolcs.
Several aftershocks followed over the next few days.
