Earthquakes Near Eketahuna

Sunday, November 18th, 2007

A burst of earthquake activity struck near Eketahuna late this evening, Sunday 18th November 2007.

Three earthquakes struck within a three minute period just after 11 p.m. The largest event of the series was an 11:04 p.m. magnitude 3.8 quake located 10 km east of Eketahuna (30 km south of Pahiatua) at a depth of 30 km. This quake was felt as far north as Halcombe (near Bulls), at Palmerston North and Eketahuna.

GeoNet has not yet analysed data for the two other events of a similar (but lesser size) that struck just after 11:05 p.m. and at 11:07 p.m., but seismograph traces suggest a similar location and depth.
