Nepal Earthquake Lifted Kathmandu, but Shrank Everest

According to Home Ministry, at least 5,017 died and around 10,224 people have been injured as of Wednesday evening.

The first good view of the aftermath of Nepal's deadly earthquake from a satellite reveals that a broad swath of ground near Kathmandu lifted vertically, by about 3 feet (1 meter), which could explain why damage in the city was so severe. The new information comes from Europe's Sentinel-1a radar satellite.

According to the early analysis, a region 75 miles (120 kilometres) long by 30 miles (50 km) wide lifted upwards by as much as a 3 feet during the earthquake, said Tim Wright, a geophysicist at the University of Leeds in the United Kingdom. This uplift peaked only 10 miles (17 km) from Kathmandu, even though the city was relatively far from the earthquake's epicentre. That's one of the reasons why Kathmandu has so much damage.

The radar images reveal that some of the world's tallest peaks — including Mount Everest — dropped by about 1 inch (2.5 cm)
