Shopkeepers in Santiago are back in business after a state of emergency was lifted and power was restored to most homes following Chile's worst blackout in over a decade. "Everyone was nervous, worried. No one could make phone calls, there was no internet, no signal, nothing," recalls Angel Flores who works in a supermarket. According to the Senapred disaster response agency, the outage affected an area stretching all the way from Arica in the long, narrow South American country's north to Los Lagos in the south -- home to more than 90 percent of Chile's 20 million people.
