No tsunami expected after earthquake off New Zealand

NEW ZEALAND civil defence authorities expected stronger than normal ocean currents and a possible increase in the size of waves around the eastern coast, but no wall of water after a magnitude 7.8 earthquake struck in the Pacific Ocean north-east of the country.

A tsunami warning was issued for eastern coastal areas of the North Island, including the country’s main city Auckland, with the first surge expected just before 9am local time (10pm Irish time).

However, the US Pacific Tsunami Centre, which issued the original warning after the quake, later cancelled its warning.

New Zealand civil defence maintained a warning that people should stay out of the water and away from beaches in the target areas.

“We might get quite extreme currents, so it is a threat to boats, but we’re not anticipating damage to land,” Clive Manly the civil defence controller for the Auckland region, told Radio New Zealand.

He said it was possible that waves of up to a metre above normal heights might occur.

The US Geological Survey said the quake struck at 7:03am on Thursday (8:03pm Irish time on Wednesday) at the epicentre, 131 miles (211km) east of Raoul Island, part of the Kermadec archipelago, and was only 30 miles (48km) deep, the USGS said.

The Kermadec Islands are uninhabited except for science and conservation teams, and sit around 1180 kilometres north east of New Zealand.

They sit in a geologically active region of the South Pacific where the Pacific and Indo-Australian tectonic plates meet, and large earth tremors are not unusual.

New Zealand has been more alert to earthquakes since the South Island city of Christchurch, was struck by two devastating quakes in September last year and in February this year.

The latter killed 181 people and caused an estimated NZ$15 billion (€8.67 billion) of damage.
