In the early hours of Monday, around 5:36 am, Delhi residents were woken up by strong tremors, with several people rushing out of their homes. Though the quake was at a magnitude of 4.0 on the Richter scale, with a depth of five kilometres, the effect of the jolt left people in shock.

Shallow earthquakes, originating five or 10 kilometres below the surface, tend to cause more damage than those originating deep below the surface.
