Check out the train wreck and volcano.
I like the expression on the face of the man in the cab in the last picture. Sort of bemused. And the pink one was very striking.
All the oil spill pictures make me kind of sick to my stomach. 
This is a really well done series. I like the combination of major world events and then people just living their lives in tiny moments that got captured. The second volcano image is indeed stunning.
Note to self: don’t live in a mobile home park in a place called Slaughterville, Oklahoma.
