There's that word again. "Heavy." Why are things so heavy in the future? Is there a problem with the Earth's gravitational pull?

People are dead and trapped under collapsed buildings in Kaikora and this is what upsets you?

I'd love to know the justification for down voting this comment.

Currently in Wellington. Was fucking shaky, seriously thought the building was about to collapse. This was ~500 km from the epicenter. We were evacuated and let back in. All the planning in the world doesn't prepare you for the real thing, the first thing you're meant to do is keep calm, and I sure as hell didn't. I sprinted right the fuck out of my apartment building, I have 4 levels above me, hiding under a table w…

You're 500km north of epicentre and felt that. Im 150km south of epicentre and felt nothing.

Anyone know of a group or website which is tracking the incidence and intensity of earthquakes over time?

http://www.globalcmt.org/ Scroll to the bottom and look at the chart of cumulative energy (moment) release over time. This is probably the easiest visualization what you're looking for without going to scientific papers. It only goes back to the 1970s though. The big steps are the Sumatran earthquakes and Tohoku (Japan). There were some equally big steps in the 1950s. As far as I know (and I do this professionally) t…

You're the real MVP. Thanks for your understanding of my question and the info. I get what you're saying about cumulative energy release over time and it's interesting to note the effect that earthquakes' periodicity has on how we need to sample the data. Very useful.

He is quoting the movie "Back to the Future" http://www.imdb.com/title/tt0088763/quotes?item=qt0416301

It doesn't matter, it's not appropriate when people are trapped under collapsed buildings and are dead.

You seem to know something that others don't. What's your source on that?

Anyone know what the lights were about? http://www.newshub.co.nz/nznews/strange-lights-during-earthq... or is it a hoax. I'm in Palmerston North a long way away, but that was the biggest quake I've felt.

Could there be any connection to the moon's current proximity to Earth? Does anyone know to what extent the moon's gravity can influence earthquakes? Tides are one thing, but it seems plausible that the moon being closer to earth than it has been in 68 years could be moving the plates a bit more than usual.

I was part of the first response for the Christchurch earthquake providing technical support and co-workers in my old job are trained USAR engineers that were deployed overnight. But most of this information is from the NZ media. We aren't talking high fatalities, but USAR are looking for a couple of missing people and there are buildings that have collapsed, people were also stuck under a vat in a winery and had to be cut out. There are two people dead but not much information is coming out of the most effected area because most communications are down.

There was a seismologist talking about that this morning. There is an effect that correlates with lunar cycles, but it is a very faint signal in a lot of random noise.

So it might cause some faults that are about to rupture to release a bit earlier than otherwise, but it's not a useful predictor of anything.

Given what ChCh went through, I really hope Wellington takes quake-proofing its more risk-prone buildings seriously. I say that every time an earthquake causes damage there, but still the building owners ask for more time and the council gives it.

Yeah Wellington has always taken it seriously, I remember the building where I worked in 2002 had a sticker on it by the council saying the building wasn't earthquake safe. The buildings here are much more earthquake safe than Christchurch but also the damage potential is much higher.

Great. Do you have a pic of the sticker? I'm moving to Umbria, Italy...
