Karachi, Pakistan’s largest city and economic hub, has been rattled by over 60 mild earthquakes between June and mid-July 2025. Most were small—magnitudes between 1.5 and 3.8—but their frequency, shallow depth, and clustering along the Landhi–Malir–Korangi corridor have reignited urgent questions about the city’s seismic safety.

Scientists warn that Karachi lies within the tectonically active Karachi Arc, where the Eurasian, Indian, and Arabian plates interact. This region sits close to a triple plate junction off the Makran coast—a zone capable of producing very large earthquakes and tsunamis.

Historical events from this system include the 1935 Quetta earthquake, the 1945 Makran earthquake and tsunami, the 2001 Bhuj earthquake, and the 2013 Awaran earthquake.
