Small tremors could roll on for BOP
Canterbury has had their fair share of quakes over the last couple of years and now are parts of the Bay of Plenty also experiencing just a few?
A swarm of earthquakes rattled the Bay of Plenty last night, and a seismologist says the rumbling could continue for a few days.
A magnitude 3.3 quake struck 10 kilometres north of Kawerau at 7.47pm last night. It was followed by a magnitude 2.9 quake at 8.52pm and a magnitude 2.4 quake at 9.18pm, both which were only 2km deep.
The quakes were felt in Kawerau, Whakatane and Onepu, according to "felt it" reports on GNS Science.
A swarm of earthquakes like these usually occurred in the area every couple of years and could go on for days, GNS seismologist John Ristau said.
"You tend to get basically what we call a swarm of earthquakes, so small earthquakes that happen over time, but not necessarily a big single earthquake," Ristau said.
"These sorts of events are often associated with volcanic areas."
The Bay of Plenty is part of the Taupo Volcanic Zone.
Earthquakes in the Bay of Plenty were usually less than magnitude 4, but some centred near White Island were greater than magnitude 5, Ristell said.
However, larger quakes can and do occur.
