Iran Train Crash

I heard about the runaway train explosion in Iran on the radio the other day. I would imagine a train full of fuel, chemicals, and fertilizer and nice fluffy cotton certainly would be prone to combustion. Apparently the explosion registered 3.6 on the Richter scale. The villages that were destroyed were built of the same mud-brick structures that completely disintegrated in the Bam earthquake in December.

Such devastation. Complete and utter ruin. Does it ever stop? Sheesh.
