Barely hours after northern India felt tremors of a major earthquake, mild tremors were felt in Delhi on Wednesday again at 4.22 pm. The National Centre for Seismology said that Wednesday's earthquake had its epicentre in West Delhi.


Earlier, earthquake tremors were felt in Delhi on Tuesday night as well. At least 11 people were killed, while more than 100 people were injured after a magnitude 6.6 earthquake jolted Pakistan and Afghanistan on Tuesday. The epicentre was in Afghanistan and the affected countries included Pakistan, Turkmenistan, Kazakhstan, Tajikistan, Uzbekistan, China, and Kyrgyzstan, reports said.

Strong tremors from the earthquake were also felt in Delhi-NCR and across much of northern India last night. 


"An earthquake with a magnitude of 6.6 on the Richter Scale hit 133km SSE of Fayzabad, Afghanistan today at 10:17 pm IST," said National Centre for Seismology. The US Geological Survey said the centre of the magnitude 6.5 quake was 40km (25 miles) south-south-east of Jurm in Afghanistan’s mountainous Hindukush region, bordering Pakistan and Tajikistan.


Afghanistan’s disaster mitigation ministry told Reuters that at least two people were killed in Laghman province. In neighboring Pakistan, at least nine people died, including a 13-year-old girl who died when a wall collapsed at her home, and at least 100 others were injured.


Meanwhile, the National Disaster Management Authority said on Wednesday that as much as 59% of India's land area faces medium to high risk of earthquakes. The NDMA said that the entire Himalayan region is known to be prone to large earthquakes of magnitude 8 on the Richter scale. In a relatively short span of 50 years, there have been four such large earthquakes — Shillong (magnitude 8.7) in 1897, Kangra (magnitude 8.0) in 1905, Bihar-Nepal (magnitude 8.3) in 1934, and Assam-Tibet (magnitude 8.6) in 1950. Scientific publications have warned about the possibility of a large powerful earthquake (magnitude 8) in the Himalayan region again very soon.

The NDMA attributed the increased risk to the widespread unscientific constructions that include multi-storied apartments, large factories, malls, supermarkets, and warehouses as well as other brick-and-mortar buildings.
