At 9:04am NZDT on the 5th January 2016 a local magnitude 4.2 earthquake struck 15 kilometres east of Seddon. This earthquake is the first moderate aftershock to the Seddon Sequence of July and August 2013. Currently GeoNet has received more than 160 felt reports, primarily from Blenheim and Wellington, but also with reports from Picton and Seddon. The maximum felt intensity was MM5 (moderate) in Blenheim, a usual location for maximum intensities from Seddon earthquakes.
This earthquake has not yet been revised, so it's location needs to treated with caution. Currently it is located beneath Cape Campbell at a depth of 37 kilometres, placing it deep within the Pacific Plate. Whilst the location is very plausible, the depth is more questionable.
More to follow...
