Wow, just got off the phone with a friend who said she felt an earthquake here in Doylestown, Pa. Frankly, I thought she was nuts and had just felt the effects of some nearby quarry blasting or some such, even though she'd said the whole building was shaking.

I'm just a few miles north, and didn't feel a thing.

Doylestown is just 15 miles from me,and we definitly felt it.
Center City Philly evacuated buildings.
 
Isn't the earth much softer back East than here in the West (mostly harder, granite). Would explain the larger reach, and intensity.
Seismic waves travel at different speeds in different types of rocks. Passing from rock to soil, the waves slow down but get bigger. A soft, loose soil will shake more intensely than hard rock at the same distance from the same earthquake. The looser and thicker the soil is, the greater the energy movement will be.

Some of the big buildings in Rosslyn were briefly evacuated.

From the USGS website:

Q: During an EQ should you head for the doorway?

A: Only if you live in an old, unreinforced adobe house. In modern homes doorways are no stronger than any other parts of the house and usually have doors that will swing and can injure you. YOU ARE SAFER PRACTICING THE DUCK, COVER, AND HOLD under a sturdy piece of furniture.

Like I said, I've thought I've heard that it isn't the recommended thing to do anymore.
 
Do we really want government in Washington to go back into the building? The quake is the safest Ive felt in a long time.

Is standing on the sidewalk safer than being inside? If something falls off the side of the building it's pretty much guaranteed to hit someone below, and if it collapses everyone is dead either way.

Yeah I was thinking that too. I assume the quake set off some sort of alarm and it was mandatory that they evacuate.

It is not safe. There is a greater risk of death or injury by falling debris. Studies from Japan(Previous earthquakes, not the one that happened in 2011) suggest that most people died from falling debris/windows while trying to get out of the buildings.

If you're going to go outside, you're supposed to go to an open area, not stand next to the building like pictured.
 
I'm on the 75th floor of the empire state building here. Shook like crazy. I got the hell out.

Tall buildings like that don't worry me. Those kind of buildings have dampers installed due to having to deal with wind loads. They are probably safer to be in than smaller buildings that are built solid with no room to move.
