CERA have produced a video explaining the extent of the damage caused to the Cathedral by the earthquakes on the 23rd of December last year. The 4m 58sec video is a tour of the outside of the Cathedral with explanations of the damage done, and the increased weaknesses in the structure. There are also a few shots from photographs taken inside after the 23rd.
The video is on the CERA website here.
