One woman was injured after falling and fracturing her hand in Delhi. Minor damage i.e. broken plaster and cracks, occurred in some parts of Delhi. For example, in the Civil Lines area, plaster was dislodged from walls. This earthquake was strongly felt throughout Delhi and the National Capital Region causing some panic. Following the earthquake, incorrect media reports from an unknown source claiming the earthquake had a magnitude of M6.6 added to the panic and confusion. Many people were woken up and many went outdoors.

Outside Delhi, strong tremors were felt at Gurgaon, Faridabad, Mawana, Sardhana and Sonepat in Haryana and at Ghaziabad and NOIDA in Uttar Pradesh. Elsewhere in Uttar Pradesh, it was felt mildly at Agra, Bagpat, Bijnor, Bulandshahr, Meerut, Muzaffarnagar and Saharanpur. Tremors were also felt as far as Chandigarh, Dehra Dun and unusually, in the Kashmir Valley. There have been no injuries or fatalities as a result of this earthquake.

This is one of the strongest earthquakes in the Delhi region since 2007 when a Mb=4.7 earthquake struck the region causing minor damage and widespread panic. The strongest known earthquakes in the Delhi region include the M6.0 Khurja-Bulandshahr earthquake on 10 October 1956, the M6.0 Gurgaon earthquake on 27 August 1960 and the Mb=5.6 Moradabad earthquake on 15 August 1966. Historically, the 15 July 1720 earthquake in the Delhi region caused the greatest damage in the city causing many deaths and widespread damage including knocking down large parts of the Shaharepanah (city wall) in Old Delhi from Kabuli Gate to Lal Darwaza and the battlements of the Fatehpuri Masjid.
