"Since Thursday, 196 earthquakes have been located, 22 earthquakes of magnitude 3 or greater have occurred in the last 24 hours, and the largest three are M3.9, M3.8, and M3.8," she said.
"The swarm appears to be tectonic in nature, unrelated to volcanic processes."
Deligne said there may be a heightened risk of landslides as the earthquakes were shallow and local and the island's material was relatively weak.
"There are no changes in volcano monitoring parameters or the level of volcanic activity at Whakaari/White Island," she said.
"Our observations are consistent with minor volcanic unrest and the Volcanic Alert Level remains at 1 while the Aviation Colour Code stays at Green.
"While Volcano Alert Level 1 is mostly associated with environmental hazards, eruptions can still occur with little or no warning.
"GNS Science continues to closely monitor Whakaari/White Island and our other active volcanoes.
"There is no further Volcanic Alert Bulletin planned at this stage."
