There has been a micro-earthquake last night under the Firth of Thames registering a magnitude 1.3 by GeoNet at 8:30 pm. It's in the same location as the 19th February magnitude 2.0 quake next to the Kerepehi fault line that reaches under the Firth of Thames from the Hauraki Plains. A quake this size is unlikely to have been felt. 37 quakes have been recorded in this area since GeoNet records began which includes the small swarm of 8 quakes in 1963.
