302:, further north. The 700 km (430 mi) extent combined with an estimated displacement of ten metres gives a maximum estimated magnitude of 8.8 on the moment magnitude scale. More recent research suggested a shorter rupture measuring 500 km (310 mi), which combined with estimated displacement of 9 to 16 meters gives an estimated magnitude of 8.5 on the moment magnitude scale. Other workers have pointed out that neither the subsidence, which could be due to lateral spreading, nor the uplift, which is not unequivocally linked to the 1762 earthquake, necessarily provide a reasonable estimate for the size of this event and prefer to regard this as a magnitude 7–8 earthquake.

In
Chittagong, it was reported that no buildings or walls built of brick had escaped either destruction or serious damage. The East India Company's factory inside the fort was so badly damaged that it could no longer be safely used. An area of about 60 square miles (160 km) permanently subsided

The earthquake lasted for about four minutes at
Chittagong. The epicentre is not well-constrained and likely locations have varied from near Chittagong to along the Arakan coast. The extent of the rupture is uncertain but may have been as much as 700 km (430 mi) along the plate interface.
