Earthquake
editThe earthquake, with its epicenter 97.6 kilometers south-southwest of Pasni in Balochistan, unleashed a tsunami that caused damage along the Makran coastal region. Deaths from the event were reported to be at least 300 and as many as 4,000 people.[5]
Another very large earthquake (7.3 Ms) occurred in nearly the same location on August 5, 1947, but not much is known about the event or its effects.[6]
