Washington Post readers added hundreds of locations to this map Friday morning describing their experience during the earthquake. We have since closed collaboration on the map because it has become strained by the volume of placemarks.
**NOTE: This map contains numerous errors. A Google rep tells us someone went in to the map this morning and moved dozens of placemarks, an unfortunate risk of open collaboration projects like this. Sorry to our readers. **
