Since the flames erupted in and around Los Angeles, scores of residents have returned to their still smouldering neighbourhoods even as the threat of new fires persisted and the nation’s second-largest city remained unsettled. For some, it was a first look at the staggering reality of what was lost as the region of 13 million people grapples with the gargantuan challenge of overcoming the disaster and rebuilding.

Since the fires first began popping up around a densely populated, 25-mile (40-kilometer) expanse north of downtown LA, they have burned more than 12,000 structures, a term that includes homes, apartment buildings, businesses, outbuildings and vehicles. No cause has been identified yet for the largest fires.
