February 17, 2010 (San Diego's East County) --- Early last Sunday morning, a magnitude (M)4.5 earthquake along with subsequent aftershocks struck Baja California, Mexico.  It was felt in East County and as far north as Oceanside. 

Although we experience these temblors often, it is beneficial to know what to do if we find ourselves inside a building while at work, enjoying a meal at a restaurant, taking in the latest blockbuster movie at the theatre, or cheering on our favorite team in the stadium.
