GeoNet was able to locate 19 of the events. Their magnitudes ranged from M1.4 to M2.5, while the depths ranged between 9 and 5 kilometres.
Volcanologist Brad Scott commented that this is very typical of the earthquake activity in this area. Swarms are often characterised by no one main or large event, with many of the events being about the same size. Nine of the events in this swarm range M2.1 to M2.5. There are also many events too small to be located.
The events were too small to be widely felt or cause any damage. The two felt reports we have received indicate only weak shaking was experienced.
