According to CNN, I felt the earthquake in Los Angeles all the way out here in Las Vegas, albeit only "slightly."
Also, according to Wolf Blitzer, the earthquake is a nightmare scenario. Wolf seemed a bit disappointed when the Mayor of LA told him that he wasn't aware of any major injuries or structural damage.
p.s.: I did feel the Joshua Tree earthquake and the Nisqually quake, both of which were much stronger (7.0 and 6.8 respectively) than today's (5.4).
