>> DAVE MALKOFF, GREAT REPORTING. THANKS SO MUCH. >>> AN EARTHQUAKE ROCKED PARTS OF SOUTHERN CALIFORNIA THURSDAY ACCORDING TO THE U.S. GEOLOGICAL SURVEY. THE 4.7 QUAKE STRUCK ROUGHLY FOUR MILES NORTH OF MALIBU. THERE WERE SEVERAL SMALL AFTERSHOCKS, BUT THANKFULLY, THERE WERE NO REPORTS OF INJURIES OR SERIOUS DAMAGE. MANY PEOPLE IN THE AREA WERE NOT ONLY JOSTLED IN THEIR BEDS IN THE MORNING, BUT IF THEY RUSHED TO THE WINDOW TO SEE WHAT WAS GOING ON, THEY PEERED THROUGH YET ANOTHER DAY OF ORANGE HAZE. MORE THAN A DOZEN WILDFIRES ARE BURNING IN THE STATE WITH AT LEAST THREE BIG ONES IN SOUTHERN CALIFORNIA. BEN TRACY IS ON THE GROUND. >> Reporter: JOHN, THIS IS JUST SOME OF THE DESTRUCTION LEFT BEHIND BY THE AIRPORT FIRE WHICH TORE THROUGH PARTS OF TWO DIFFERENT COUNTIES SOUTH OF LOS ANGELES. THIS IS ONE OF THREE MAJOR FIRES IN THE AREA THAT HAVE NOW CHARRED MORE THAN 110,000 ACRES, DESTROYING DOZENS OF HOMES, INJURING SEVERAL PEOPLE, INCLUDING FIREFIGHTERS. THERE ARE NOW 6,000 FIRE PERSONNEL WORKING THESE THREE FIRES AND THAT IS REALLY STRAINING THE RESOURCES OF BOTH CAL FIRE AND THE FOLKS THEY'RE BRINGING IN FROM OTHER STATES AS WELL AS THE FEDERAL GOVERNMENT. THE CAUSE OF TWO OF THESE FIRES IS STILL BEING INVESTIGATED. AS IT PERTAINS TO THE LINE FIRE IN SAN BERNARDINO COUNTY, OFFICIALS THERE BELIEVE THAT IS ACTUALLY ARSON AND THEY HAVE NOW CHARGED 34-YEAR-OLD JUSTIN HOLSTONBERG WITH ARSON, INJURY TO A FIREFIGHTER AND THE USE OF THREE INCENDIARY DEVICES AND THE DISTRICT ATTORNEY BELIEVES HE WAS INVOLVED IN SETTING OTHER FIRES IN THE AREA. FOR A BIT OF GOOD NEWS, THE WEATHER HAS CHANGED DRAMATICALLY. TEMPERATURES HAVE DROPPED AND THE WINDS HAVE DIED DOWN. THAT SHOULD BE REALLY BENEFICIAL FOR FIREFIGHTERS, BUT IT COULD BE SEVERAL DAYS BEFORE PEOPLE ARE ALLOWED BACK INTO NEIGHBORHOODS LIKE THIS
