• Gamer was playing World of Warcraft on camera when quake happened
• Sierra can be heard freaking out as tremors knock him off his chair
• He tries to keep playing but falls down and eventually flees out the door
• Despite his obvious trauma his friends are less than sympathetic
It was one of the biggest earthquakes in New Zealand for years - killing two people, damaging hundreds of homes and causing a tsunami up to five metres high.
So World of Warcraft gamer Delrio Sierra can perhaps be forgiven for freaking out while accidentally live-streaming the disaster online.
But despite Sierra's obvious panic his fellow teammates couldn't care less, encouraging him to keep playing, adding: "No-one cares if you live or die".
Astonishingly Sierra does attempt to stay at his keyboard, poking his head up from underneath his desk in a desperate bid to keep questing.
But the tremors eventually prove too much and he is literally knocked off his feet, sending him scrambling out the door.
At one point he can be heard checking if his girlfriend is all right, while saying "f*** this is huge".
It is not known exactly where the footage was filmed, though it is believed to be in Christchurch.
Meanwhile his friends continue to mercilessly mock his fear, telling him he's making a big deal out of nothing.
One person can be heard saying: "It's a f***ing two on the Richter scale, c***. You're crying like my f***ing sister. Shut the f*** up."
But moments later it starts to dawn on them that something big might actually have happened as they tune into his video feed and notice he's gone from the screen.
Another player remarks the tremors can also be felt in Wellington as Mr Sierra comes back on camera, still shaking with fright.
"Dude, there was a f***ing huge one. F***," he says.
"Oh my God. Holy s***."
Moments later he looks up the strength of the quake before realising it was much more intense than he thought.
While Mr Sierra says 7.5 in the video, the true strength has now been measured at 7.8, followed by a 6.3 aftershock.
By comparison the 2011 earthquake that killed 185 people in Christchurch was only a 6.3, though the epicenter was much closer to the city.
