The Raised Seabed and Lagoon Created by Kaikoura Earthquake

shagen454 says...

That is absolutely incredible. Recently moved away from San Francisco after 15 years, counting my blessings that I only experienced one 6.1 tremor. That one was scary enough to make my knees shake on end for many minutes afterwards but also not exactly dangerous enough -to not be a little fascinating. But, once you start getting into 7+s, I'm sure it's absolutely terrifying beyond description, especially liquefaction, freaks me out!

Extreme Soil Liquefaction

garmachi says...

Liquefaction is caused by extremely fast and regular vibrations in a substance composed of uniformly sized particles. The shakiness of that video induced the phenomenon.

Atheism 2.0 - TED talk by Alain de Botton

ChaosEngine says...

>> ^bareboards2:

philosophy
I love this talk. I find that some atheists can be just as dogmatic and invasive in imposing their point of view as any evangelical. This guy has it nailed.


There were some interesting ideas, but mostly I wasn't impressed.

He opens by talking about the "kind of atheist that likes christmas carols". So, for example, Richard Dawkins?

He then talks about how we can use the "tools of religion" to make our lives better. He's essentially talking about 2 things, community and indoctrination.

Community, I think we can all agree happens easily without religion. Just look at this site. For a more real world example, last years earthquake in my home town saw groups of people coming together to dig out liquefaction from each others houses.

Indoctrination, on the other hand, I can live without.

As for the sense of mysticism or wonder, again that's not an issue I worry about. On this site alone there are hundreds of videos that talk about a secular sense of wonder about the universe (pretty much anything with Carl Sagan, Neil DeGrasse Tyson or Brian Cox). At a more local level, that "sense of belonging to something bigger" comes back to community for me. Whether that's a group of friends, a city trying to rebuild itself, or even in the larger sense that we all inhabit the same rock flying through space.

Ground still moving in Japan

Seriously though that some obvious liquidification going on right there. Lets quote Wikipedia:

"Soil liquefaction describes a phenomenon whereby a saturated soil substantially loses strength and stiffness in response to an applied stress"

Ground still moving in Japan

kceaton1 says...

It's ground water forced up and basically related to sand "volcanoes". This is formed due to liquefaction (Salt Lake City will get the same thing when our earthquake comes. This happens all the time in earthquakes if the land is an ancient seabed, has ground water near the surface, or any other situation that is similair like this reclaimed land.

Don't worry about it too much unless it's a huge one (which would be rare). The big problem is that since it acts like quicksand all the buildings (or anything weighing the right amount) will sink into the ground.
