Another earthquake swarm has commenced activity 10 km east of Seddon in the South Island.
The swarm of shallow earthquakes commenced with a magnitude 3.9 event at 4:54 p.m. on Sunday December 18th. This was followed by a magnitude 3.6 event at 6:29 p.m. A magnitude 3.7 earthquake, which was felt in Blenheim, was recorded by Geonet at 4:19 p.m. today.
The area was plagued by a similar swarm of earthquakes last month when 9 tremors occurred between November 1st and 11th. Two of the largest events shook goods off shelves in Blenheim. The area also experienced a series of 7 other earthquakes nearby at the same time.
The latest swarm does not appear to be attended by nearby quakes at this stage, the most recent other nearby event being a magnitude 2.9 quake 20 km north-east of Seddon on December 7th.
