A 6.1 greatness quake struck 585kilometres southwest of Invercargill
The tremor was at first delegated a solid shake hitting at profundity of 10km
Tremors may have been felt in Balclutha, Gore, Invercargill, and Lumsden
The tremor was trailed by a 5.1 greatness shake which was felt in Wellington
New Zealand has been shaken by a 6.1 greatness seismic tremor which struck southwest of Invercargill, trailed by a 5.1 size shudder upper east of Seddon.
The tremor caused ‘direct shaking’ detailed Geonet.
Introductory characterizations called it a solid shudder, hitting 585km southwest of Invercargill at a profundity of 10km.
Tremors may have been felt in Balclutha, Gore, Invercargill, Lumsden, Roxburgh, Te Anau and Tuatapere, while the Seddon shudder was felt unequivocally in Wellington.
New Zealand specialists have issued a suggestion to ‘drop, cover, and hold’ in case of a seismic tremor.
The second shake was sufficiently solid to be felt in country’s capital, with Metlink Wellington detailing the sum total of what trains have been ceased.
A seismologist said the two tremors – which hit precisely a hour separated – were not connected.
GNS seismologist Dr Anna Kaiser said there was no connection to the Mexico City tremor that has left more than 100 individuals dead.
‘It’s surely something that can’t be experimentally demonstrated,’ she said.
Dr Kaiser said that despite the fact that seismic tremors can trigger post-quake tremors close-by, that is probably not going to be the reason for the Seddon shudder.
‘However, clearly that is [aftershocks] not a system that could clarify the seismic tremor in the Cook Strait since it was too far away to be caused by that sort of stress change,’ she said.
The main shake hit a seismically dynamic zone almost a plate limit where the Australian plate plunges beneath the Pacific plate, the NZ Herald revealed.
This limit is known as the Puysegur trench, and extends for 800km between New Zealand’s South Island and a point in the Southern Ocean 400km west of the Auckland Islands.
A comparable 6.4 shake hit the trench in July, with an epicenter 190km southwest of the Snares Islands.
That shake was felt all around the South Island.
