While we consider the complex threads of causality, like those from earthquake to tsunami to infrastructure damage to perverse increases in the value of the yen, revealed by the recent tragedies, we realize how tightly coupled everything is.
This image has been much passed around the earth science community in Texas. This one is the depth of the local aquifer in Central Texas. The compression wave from the earthquake is strikingly obvious as it passes by, affecting the porosity of the aquifer.
After a massive quake, the whole earth rings like a bell. It's all connected; the lines we draw between "us" and "them", between "here" and "there" are just convention and ritual, empty ceremony.
