  The new information comes from Europe's Sentinel-1A radar satellite. Scientists are racing to interpret the Sentinel data, which were made available April 29 just hours after the satellite passed over Nepal. The preliminary data can help guide relief efforts on the ground by identifying areas that were damaged or hit by landslides.
  The radar images reveal that some of the world's tallest peaks -- including Mount Everest -- dropped by about 1 inch (2.5 cm), according to the nonprofit UNAVCO, a geoscience research consortium. That's because the Earth's crust relaxed in the areas north of the Kathmandu, after the earthquake released pent-up strain.

  Scientists plan to continue monitoring ground changes in Nepal. For instance, the fault did not break all the way up to the Earth's surface, which may mean that some strain that built up prior to the earthquake still needs to be unleashed. The fault could release this energy with more earthquakes or by slowly shifting without triggering major temblors -- a phenomenon called creep. Further studies will also help researchers understand how the earthquake stressed other faults on either side of the rupture.
