Karachi has experienced 19 mild earthquakes since Sunday evening, confirmed the Pakistan Meteorological Department (PMD) on Tuesday. The latest tremor hit at 9:57am on June 3, registering a magnitude of 2.8. Its epicentre was 15km northeast of Malir at a depth of 40km.
Earlier, two tremors were recorded late Monday night. The first struck at midnight with a magnitude of 2.6, followed by another at 12:23am measuring 2.8. Both originated northeast of Malir at a depth of 40km.
Another noticeable jolt was felt Tuesday morning at 6:42am. It measured 3.2 in magnitude and was located near Korangi with a shallower depth of 11km. Tremors were widely felt in Landhi, Malir, Quaidabad, and surrounding areas. So far, no injuries or structural damages have been reported.
Landhi Fault Line Reactivated, Says PMD
Chief Meteorologist Aamir Haider explained the repeated quakes are due to the reactivation of the Landhi Fault Line. He described the phenomenon as a “normalisation phase,” during which seismic energy is being slowly released.
“These small tremors are actually helpful,” Haider noted. “They reduce the risk of a large, destructive quake by gradually releasing pressure.”
He added that such mild seismic activity could continue for several more days. The shallow depth of the recent tremors has made them more noticeable across the city. He also reassured the public that buildings situated above the fault line should be able to withstand quakes up to magnitude 6.
Haider further mentioned another fault line near Thana Bula Khan is also contributing to the ongoing tremors. Addressing public concern over cracks in homes, he clarified that these are more likely due to construction flaws than seismic damage.
