Eerie lights appeared in the sky during the 7.8 magnitude earthquake which shook two days ago.
There have now been four quakes in New Zealand over the past 48 hours.
The latest, today, measured 5.4 on the Richter scale, according to the USGS.
It hit the town of Blenheim – in the most northern point of the country’s southern island, just before 6.09pm (local time).
Yesterday, a third strong quake, measuring 5.8-magnitude, struck near Kaikoura on the east coast of the South Island.
The tremors come just two days after the 7.8 magnitude earthquake killed two people, left more than a thousand stranded and caused billions of pounds worth of damage, and a 7.5 magnitude tremor also struck.
Strange explanations for starting the seismic activity, which have emerged on online conspiracy forums, have also included the gravitational pull of the moon coming closer to the Earth during the supermoon, the Large Hadron Collider (LHC) scientific experiment in Geneva, and an alleged secret government weather altering experiment known as Haarp.
There have been many claims the LHC, which collides particles together in 15 miles of tunnels under the French-Swiss border to discover the secrets of how the universe formed, can cause earthquakes due to energy being released underground.
There is no scientific evidence to back up this theory, but that has not stopped conspiracy theorists linking experiments at the LHC to actual earthquakes, including those in Italy this year.
Conspiracists have jumped on the fact the Christchurch quake was actually felt by the LHC to try to join the dots and blame the ginormous experiment.
Blue lights including this were seen during the 7.8 magnitude New Zealand earthquake.
It happened after CERN boffins posted a still from a graph of their beams showing they were actually rattled by the earthquake as it happened.
YouTube conspiracy theory channel BP Earthwatch picked up on this in a video about the quake.
The video prompted a heated debate among other conspiracy theorists about what caused the New Zealand quake.
One viewer, with the user name Peg Leg, posted: “What if it was actually the other way around? What if something at CERN caused the quake in NZ?”
Kelly Bartee replied: “CERN playing with fire.”
User shellsies said: “Seek the Truth, speak the truth.
“The earthquakes going on in the Pacific northwest are not at all natural.
“Which leads me to believe that a lot of these aren’t either. When it’s not HAARP it’s CERN causing them.”
HAARP was a weather ion research program jointly funded by the US Air Force, US Navy, the Defense Advanced Research Projects Agency (DARPA) and universities.

Which leads me to believe that a lot of these aren’t either. When it’s not HAARP it’s CERN causing them.
It began in 1993 and at the height of conspiracies, some theorists claimed it could change weather patterns, cause earthquakes, droughts and storms.
Other wild claims included it being able to disable satellites, target enemies and even control people’s minds.
Allegations went as far as saying it caused the 1996 crash of TWA Flight 800 and the 2003 Columbia space shuttle disaster.
Scientists rubbished these claims saying all were outside HAARP’s abilities and most were beyond natural science.
Actually, based on a sub-arctic facility an Air Force-owned site near Gakona, Alaska, HAARP’s purpose was to analyse the ionosphere and investigate the potential for developing ionospheric enhancement technology for radio communications and surveillance.
It temporarily ceased in May 2013 and was officially closed a year later.
But some conspiracists claim it has been secretly continued and intensified, with often devastating results.
One user, with the name Epic Quintessenc, posted: “Flashing lights are HAARP.
“Ask any Kiwi and they will tell you that the quake and tsunami were caused by HAARP.”
But, Melissa Hopeful blamed the supermoon.
She posted: “It’s the largest harvest moon since Israel became a nation in 1948 – and the same day of the Christchurch earthquake.
“Wake up church, King Jesus is coming!”
Scott C Waring, editor of ufosightingsdaily.com, is firmly blaming aliens leaving an underground bases for the quake.
He thinks the unusual lights were caused by a giant UFO coming from out of the ground.
He blogged: “UFOs are often seen during and after earthquakes, just like in this video below you see lights from a UFO that exited from the ground.
“It had to have been giant, about 1km, for the opening to cause such an earthquake as it did. Christchurch is a hotbed of UFO activity over the last five years, so this is really no surprise.”
These are, of course, all wild conspiracy theories with no scientific evidence.
Earthquake lights have been recognised by scientists as a naturally occurring phenomena, which has yet to be fully explained.
The lights have appeared as flames from the ground, flashes of lightning, or blue and green shimmers.
They usually happen where large areas of Earth pull apart, according to a 2014 study published in the journal Seismological Research Letters – Elves, Sprites & Blue Jets: Earth’s Weirdest Lightning.
It is thought an electrical charge or energy is released.
