Jose Osuna told the Televisa television network. One person was crushed in a collapsed house, the other hit by a falling wall.<br /> </p><p><br /> The tremor, felt as far north as Los Angeles, cracked main roads, toppled electricity posts and knocked down an empty multistorey car park under construction in Mexicali, a prosperous city and busy border crossing.<br /> </p><p><br /> Hundreds of people camped out overnight as smaller tremors shook buildings with cracked floors, walls and broken windows.<br /> </p><p><br /> "I wasn't going to put my family at risk. Lots of homes have cracks," said Fermin Garcia, a teacher who slept with her family in a tent pitched between two shopping centers.<br /> </p><p><br /> Broken gas pipes sparked a number of fires on Sunday, and darkened streets in Mexicali triggered car accidents, but no major buildings appeared to have collapsed.<br /> </p>
