Earthquakes Canada has confirmed a 3.8 magnitude earthquake hit an area 17 kilometres northwest of Hampton in southern New Brunswick at 9:45am this morning.
Its preliminary magnitude was reported as 3.7, but Earthquakes Canada has since upgraded it.
It was described as “intraplate earthquake,” which happens inside the tectonic plate, as opposed to an interplate earthquake, which occurs in areas at the edge of a tectonic plate.
Nick Ackerley, an Earthquakes Canada seismologist said it was caused by faults from previous mountain-building episodes and glacial rebound.
She added “This part of Canada was under glaciers until about 10,000 years ago, and when the weight of the ice was lifted off, the Earth is slowly springing back, and that causes stress in the crust of the Earth.”

A 3.8 magnitude quake could be widely felt depending on the depth at which it occurred. However, it is still considered to be a minor earthquake and unlikely to cause damage.
Earthquakes, while rarely severe, aren’t unheard of in New Brunswick.
In the spring of 2018, Earthquakes Canada recorded a “swarm” of 22 minor quakes on the western edge of the province near McAdam, a village also also rattled by a 3.3 magnitude earthquake in 2016.In November 2016, a magnitude 3.1 earthquake was recorded.
Ultimately though, the last major earthquake, a magnitude 5, hit the Miramichi area in the 1980s, the largest earthquake to have affected the Maritimes since 1929.
