The United States Navy has been carrying out ‘Full Ship Shock Trials’ off the country’s east coast.
The 40 000lb (18 143kg) explosion was detonated as part of a test to assess the aircraft carrier USS Gerald R. Ford’s ability to withstand battle conditions.
The US Geological Survey registered the explosion as a 3.9 magnitude earthquake.
Following the trials, the warship will return to a dry dock to undergo modernisation, maintenance and repairs. (BBC)
