60 Earthquake Jolted 112 km Nw of L'esperance Rock New Zealand

A 6.0 earthquake jolted 112 km NW of L’Esperance Rock, New Zealand at 04:16 GMT, Monday.

The epicenter, has a depth of 325 (200 miles) and about 112 kilometers from the nearest populated areas at L’Esperance Rock. The quake was 470 km deep beneath the Kermadec Islands and 866 kilometers from Auckland, New Zealand which according to Geoscience Australia was common to the region.

L’Experance Rock is the southernmost islet in the Kermadec Islands north of New Zealand.

The initial data recorded by Geonet was at 4.5 75 km north of Te Araroa but the second data showed 6.1 magnitude 10 km south west of Tokumaru Bay.

The earthquake confused the monitoring systems and prompted two false reading which set off a civil defense alert.  A National advisory was sent out by the Ministry of Civil Defense and Emergency Management after 4:30 p.m. advising people to check their workplaces, and homes for damage after the National Crisis Management Center was activated.

Earthquakes are usually measured using the two different waves it produces. Incorrect reading happens when the system thinks the later arriving wave was the first one. However, Dr Fry said the duty officers quickly assessed the date and has worked to make a more accurate reading.

An earthquake so far and deep would not usually be felt anywhere in New Zealand, but sometimes smaller local events embedded in the waves could result in smaller, more localised tremors.

It was not clear whether the alert was lifted after the earthquake was redefined.
