CCTV and mobile footage captures some of London's pavements exploding, including CCTV film released by Westminster city council of an incident in July. Basil Scarsella, who runs Hong Kong-based UK Power Networks, which maintains London's power cables, blames the blasts on increased rainfall, according to a report in the Standard. There have been 64 explosions reported to the Health and Safety Executive across the capital this year, compared to 51 in 2013
