The driveway of Hollywood actor Nicolas Cage’s coastal Malibu mansion collapsed Tuesday morning, leaving a huge sinkhole in front of the property.The collapse caused a gas leak just before 6am on 8 September. Utility SoCalGas said the leak was under control several hours later, but that it was temporarily shutting off natural gas services for an 85-foot (26-metre) section of the street as a precaution against coastal erosion.The mansion was damaged during a Los Angeles-area coastal flooding advisory over lingering effects of Marie, which had been a hurricane before turning back into a tropical storm.Representatives for Cage did not immediately respond to requests for comment.
