Tremors were felt in parts of Delhi-NCR on Sunday afternoon after a 3.4 magnitude earthquake struck the national capital. The depth of the earthquake was 5 km, the National Centre for Seismology said. Last month, Delhi was struck with earthquakes of magnitude 3.5 and 2.7 on April 12 and 13 respectively. "Praying for everyone's safety," Delhi CM Arvind Kejriwal tweeted.
