Nepal's devasteting magnitude -7.8 earthquake on saturday was primed over 80 years ago by its last massive earthquake in 1934, which razed around a quarter of Kathmandu to the ground and killed over 17,000 people.
This lates quake follows the same pattern as a duo of big tremors that occured over 700 years ago , ad results from a domino effect of strain transferring along the fault, geologists say.
Saturday's earthquake, which struck an area in central Nepal, between the capital Kathmandu and the city of Pokhara, has had a far-reaching impact. Early reports indicate that more than 2,000 people have lost their lives, with victims in Bangladesh, India, Tibet, and on Mount Everest, where avalanches were triggered.
