I felt my apartment swaying back and forth slightly, just subtly enough to make me wonder if it was coming from the construction eternally happening on Houston Street. But there was no noise. And confusing me was the lack of reaction from people on the street. The shaking lasted about 10-15 seconds but it never felt I was in danger, so I went to my roof to see what I could see. By the time I got there the people, in the building under construction to become a Union Market on Houston Street and Avenue A, had wisely evacuated.
Cell phone service here was clogged for a half hour. Nuclear plants, near epicenter were automatically shut down, something to keep an eye on.
Update: the power company officials say no release to environment, no damage to plant or dam and back-up diesel is running.
