Plate Boundary Map
Nepal lies towards the southern limit of the diffuse collisional boundary where the Indian Plate underthrusts the Eurasian Plate, occupying the central sector of the Himalayan arc, nearly one-third of the 2,400 km (1,500 mi) long Himalayas. Geologically, the Nepal Himalayas are sub-divided into five tectonic zones from north to south, east to west and almost parallel to sub-parallel. These five distinct morpho-geotectonic zones are: (1) Terai Plain, (2) Sub Himalaya (Sivalik Range), (3) Lesser Himalaya (Mahabharat Range and mid valleys), (4) Higher Himalaya, and (5) Inner Himalaya (Tibetan Tethys). Each of these zones is clearly identified by their morphological, geological, and tectonic features.
The convergence rate between the plates in central Nepal is about 45 mm (1.8 in) per year. The location, magnitude, and focal mechanism of the earthquake suggest that it was caused by a slip along the Main Frontal Thrust.

Rescue and Relief
Disaster Management - Measures taken
Mobile hospitals have been transported to Nepal, and NDRF teams are at work. IAF aircraft also carried blankets, tents, tonnes of food, paramedics, stretches, and medicines.
Ensuring power & fuel supply: The government had sent teams of senior executives and engineers from state-run energy companies to Nepal with a view to ensure uninterrupted fuel supply and restore power lines.
