How the earthquake shook India

At least 42 people have died in India, most of them in Sikkim, others in neighbouring Bihar and West Bengal. The earthquake, which measured 6.8 on the Richter Scale and was centred on the Sikkim-Nepal border 64 kilometres north-west of Gangtok, is the region's worst in 60 years. Among the toughest parts of the recovery is the operation to re-open National Highway 31A which connects Sikkim to the rest of the country, and is needed to bring in food and other supplies.
