A powerful earthquake struck Nepal and sent tremors through northern India on Saturday, killing hundreds of people, toppling a 19th-century tower in the capital Kathmandu and triggering avalanches on Mount Everest, Reuters reported. There were reports of devastation in outlying areas of the Himalayan country after the quake struck with a magnitude of 7.9, its epicentre 50 miles (80 km) east of Nepal's second largest city, Pokhara. The worst quake to hit the impoverished Himalayan nation in 81 years also caused damage in neighbouring Indian states and Bangladesh. The quake was shallow, intensifying the amount of energy released over a relatively small area. A police spokesman said the death toll had reached 449 in Nepal according to an initial estimate, most from the Kathmandu Valley. There was little information coming from the outlying areas of the mountainous country and helicopters were circling overheard to get a better sense of the damage.
