Earthquake Swarm Near Wanganui Continues

The swarm of earthquakes occurring 30 km south-west of Wanganui has continued. The swarm commenced with a magnitude 4.1 earthquake just before 1 a.m. on Saturday 11th. A further four events of magnitude 4.3, 4.5, 3.8 and 4.2 occurred up until 8:10 a.m.

Another magnitude 4.2 tremor was felt in Wanganui just after two this morning according to Geonet, bringing the total number of earthquakes in the swarm to seven. All of the earthquakes have occurred at a depth of 30 km.

The latest swarm is taking place just after a series of light but deep earthquakes under the central North Island. A similar pattern of deep earthquakes occurred prior to two of the Wanganui swarms during May/July and July/August last year.

The members of the latest earthquake swarm are more numerous and slightly stronger than those of the three Wanganui swarms that occurred in 2005.
