An article recently published in Nature Geoscience led my John Elliott of Oxford University reviewed the 2015 seismic event known as the Gorkha earthquake, which reached a magnitude 7.8. This earthquake essentially shut down Mt. Everest, making 2015 the first time since 1974 that no one submitted Mt. Everest. Check out a video of landslides in the mountains that were caused by the earthquake.
Elliott and his team of authors analyzed satellite imagery, radar surveys, and LIDAR surveys to determine the movement that occurred as a result of the earthquake. They determined that the Kathmandu basin (known as the lesser Himalaya) moved 2 m south-southwest laterally and uplifted about 1 m as a result of the earthquake. The higher Himalaya, to the north, actually subsided about 0.6 m.
The research team analyzed the average growth rate of the Himalaya mountains. The mountains grow at a rate of 4 mm/year, and in recent decades as much as 7 mm/year. Elliott and his group concluded that the Himalaya Mountains grow between earthquake events, and that the earthquakes actually lessen the height of the mountains.
