11.35pm AN aftershock to the Korumburra earthquake has hit parts of Melbourne this evening, the Herald Sun reported.

The magnitude 3.7 aftershock at about 7.16pm was the second and most violent since the initial 4.4 magnitude quake hit Victoria at 11.32am today.

A second, smaller aftershock - measuring 3.3 - shook the South Gippsland town of Korumburra, with reports it was again felt in Melbourne, at 12.37pm, a spokesman from Geosciences Australia said.

The epicentre of the original quake was about 7km west of Korumburra, and was felt in Melbourne's CBD and the southeastern suburbs.

Tonight's aftershock may not be the last, according to Geosciences Australia.

Senior seismologist Clive Collins told Victorians they may feel further aftershocks, and while it was unlikely the state would ever cop anything stronger, it should never be ruled out.

"If you look at the history of recorded earthquakes in Australia, they are not increasing or decreasing necessarily, it's just the luck of the draw," he said.

"But you can have clusters of activity within the space of a year and then nothing for five years.

"People are also hearing about it a lot more because they can just jump onto the internet.''

4.09pm With the continuing drama of Christchurch's disastrous quake, people are understandably nervous about the latest rattling.

Luckily no one has been hurt and no damage reported, so a few are finding the lighter side, like Twitter user and mother of three, Kate.

@UpsideBackwards8yo didn't feel because.... they were having an earthquake drill at the time!

4.02pm The Taupo earthquake was too deep to affect the nearby volcano at Mt Ruahepo. Aftershocks are not expected.

New Zealand scientists record around 14,000 earthquakes a year, of which on average around 20 top magnitude 5.0.

3.49pm New Zealand residents have described a "side-to-side" movement of the earthquake which struck this afternoon, making people feel "woozy" and drunk.

Wellington local told stuff.co.nz: "it was like a big, slow, single hoola-hoop role, type, motion."

"An interesting sensation."

Emma Tollemache said she felt as though she was drunk and it felt like the floor was turning into a slide.

"Makes you feel for the people of Christchurch, that was just a small insight as to what they are living through," she said.

3.09pm Geoscience Australia has released seismograms of the Korumburra earthquake and say it hit at a depth of 2km.

2.51pm GeoNet reports the New Zealand earthquake hitting 30km west of Taupo (220 km southeast of Auckland), 150 km deep at 3.36pm local time.

The epicentre was below the plate boundary and according to GNS volcanologist Brad Scott, the volcanic zone of the North Island would have absorbed much of the energy.

Dr Scott also told stuff.co.nz the quake was more likely felt on the east coast of both islands.

2.38pm It's a shaky day. There are reports of a 6.5 magnitude earthquake on New Zealand's lower North Island.



The quake was felt through the lower North Island and as far south as Christchurch.

There are no immediate reports of damage but updates will be provided as they come to hand.

2.17pmVictoria is unlikely to experience stronger earthquakes than today, but Clive Collins says we shouldn't rule it out.



Speaking to the Herald Sun, the seismologist said while it may seem like earthquakes are increasing or decreasing at times, it's really just the "luck of the draw".

"But you can have clusters of activity within the space of a year and then nothing for five years.



"People are also hearing about it a lot more because they can just jump onto the internet."

The last time significant tremors hit Melbourne was in 2009 when two magnitude 4.6 quakes hit within a week of each other.

Mr Collins said the latest quake was probably part of the same fault line.

"Australia sits on the tectonic plate that runs from New Zealand to the Himalayas and we are not near any big boundaries but because the plates are moving all the time stresses can build up in local fault lines or cracks. That's what we've felt today."

2.08pm Senior seismologist Clive Collins told the Herald Sun people should prepare for more aftershocks in the coming hours.



He said a tremor measuring 3.3 had already been recorded at 12.37pm.



"There will be aftershocks, that's a certainty," he said.



"We still expect lots of smaller ones.



"After the last significant quake in Victoria there were more than 200 aftershocks."

1.02pm Geoscience Australia estimates the earthquake "could have been felt by people up to 93km away" and "could have caused damage up to 7km away" from the epicentre at Korumburra.

12.56pm Despite there being very little damage as a result of the earthquakes, it is still trending on Twitter. Perhaps due to the amount of jokes going around. One of the more popular tweets is this tongue-in-cheek offering from user @alexanderb.

@alexanderb Just saw this damage from the melb quake #melbquake



12.39pm Further aftershocks have just been felt in Melbourne and Korumburra, according to various people on Twitter.

12.20pm Residents are describing their earthquake experiences on social media and blogs. So far no one has reported serious damage. Jacqueline writes on the 3AW blog:

Working at home in Mentone and the whole desk shook like a rolling effect, rippling along. Bookends fell down in my sons bedroom. My cat was beside herself, she knew something was not right.

Warragul resident Michael O'Keefe told the Herald Sun it was the strongest he'd ever felt.



"It sounded like a truck was approaching up the street and then it was as if the truck had run into the building. Everything was rattling. It feels a bit like it's not complete, like there is another one to come.''

12.16pm The earthquake was magnitude 4.4, according to the Australian Government Geoscience website.

12.08pm Prof Ian Cartwright, of the School of Geoscience at Monash University, said earth faults that cause quakes do exist in Victoria but it was unusual for tremors to be felt across several suburbs.

"Even though we don't have major faults in Australia, there's always a little bit of movement on these faults and when they move we get small earthquakes," he told the Herald Sun.

"Most of the earthquakes in Australia tend to be 2, 3, maybe magnitude 4.

"It takes a few hours for the seismologists to get the details of exactly where it was located and how strong it was."

11.40am Residents in suburbs from South Yarra to Rowville reported the tremors.

So far there are no reports of damage.

The epicentre was at Korumburra, 3AW has reported.

The Geoscience Australia website appears to have crashed.

‘‘That was a big one,’’ tweeted one person from Rowville.
