BREAKING NEWS: New Zealand rocked by strong 6.1 magnitude earthquake as a 'powerful tremor' strikes Wellington

New Zealand has been rocked by a 6.1 magnitude earthquake which struck southwest of Invercargill, followed by a 5.1 magnitude quake northeast of Seddon.
The quake caused 'moderate shaking' reported Geonet.
Initial classifications called it a strong quake, hitting 585km southwest of Invercargill at a depth of 10km.
Tremors may have been felt in Balclutha, Gore, Invercargill, Lumsden, Roxburgh, Te Anau and Tuatapere, while the Seddon quake was felt strongly in Wellington.
New Zealand authorities have issued a reminder to 'drop, cover, and hold' in the event of an earthquake. 

The second quake was strong enough to be felt in nation's capital, with Metlink Wellington reporting all trains have been stopped.
A seismologist said the two quakes - which hit exactly an hour apart - were not linked.

People took to social media in shock to report feeling the quake and to check on on their family and friends. 
The more distant earthquake measured 6.1, USGS reported.

GNS seismologist Dr Anna Kaiser said there was no link to the Mexico City earthquake that has left more than 100 people dead.
'It's certainly something that can't be scientifically proven,' she said. 
Dr Kaiser said that although earthquakes can trigger aftershocks nearby, that is unlikely to be the cause of the Seddon quake.
'But obviously that's [aftershocks] not a mechanism that could explain the earthquake in the Cook Strait because it was too far away to be caused by that kind of stress change,' she said.

One shocked resident wrote that her city is a 'disaster waiting to happen' as Wellington was rocked by the latest in a long line of quakes.
'Rocking side to side in a rocky chair: the Wellington experience,' wrote another. 
Others made light of the tremors, with one Twitter user writing: 'Yikes that shake I thought was me moving in my seat (need to lay off the



donuts...) was actually an earthquake.'
No tsunami warnings have been issued. 
Seddon resident Pam Tawhara was looking up baking recipes on her computer when the quake struck, Stuff reported.
'It felt like a normal aftershock, then I thought "bloody hell". It was a bit scary, there was a violent, thudding jolt and it went boom, boom, boom,' she said.
No damage was done to her home, and nothing fell from her shelves.
Another Seddon resident, Wendy Caughley, reported getting a shock when she felt the earthquake.
She says she heard the quake coming - describing it as a long, loud rumble that could have been heavy vehicles moving through an adjacent vineyard.
