While working on my computer at the 17th floor of a building in Downtown San Diego, I felt the tremors right away and looked outside the window. Since all other buildings were not in close proximity, you cannot see that much the strenght of the sway but my window blind were moving to show that this was undeniably an earthquake in San Diego.
Some group of employees ended up going down the stairs from the 17th floor just to safe just in case there were any after effects. We went to a deli about 3 blocks away and stayed there for a while.
After coming back, I checked the epicenter right away. It was at 33.955 degress North and 117.765 degrees West that registered 5.4 on the Ritcher scale detected by Seismographs from USGS, Caltech, CGS, UCB, UCSD and UNR. The location was about 46 kilimeters away from the LA Civic Center.
