Wonder if it was a 'true' shaker?
A magnitude 5.5 earthquake IN PAKISTAN has occurred at:
34.87N 73.79E Depth 10km Mon Mar 20 17:40:45 2006 UTC
Time: Time Near Epicenter Mon Mar 20 22:40:45 2006
Eastern Standard Time (EST) Mon Mar 20 12:40:45 2006
Central Standard Time (CST) Mon Mar 20 11:40:45 2006
Mountain Standard Time (MST) Mon Mar 20 10:40:45 2006
Pacific Standard Time (PST) Mon Mar 20 09:40:45 2006
145 km (90 miles) NNE of ISLAMABAD, Pakistan (pop 524,000)
5.5 is usually like a heavy truck going by with a little wave action and maybe a jolt at the end -- not a big deal in Calif., but unknown what it feels like in Pakistan.
True vs. man-made?
I don't know.
It is posted. Most likely an aftershock from the major quake that hit last fall. Had another 5+ in the same area within the last week too.
