A quake that struck off White Island yesterday was not linked to recent volcanic unrest, a seismologist says.
GeoNet said the magnitude 3.4 quake struck 50km northwest of the island, off the coast of Whakatane, shortly after midday.
The 62km deep quake was of weak intensity and was unlikely to be felt on the Bay of Plenty mainland.
White Island's volcanic alert was raised to level two, or minor eruptive activity, after a small eruption in early August.
But the alert has since dropped to level one, which means signs of volcanic unrest still remain.
