Did the earth move for you this morning?
The BBC reports that a World War II mine was detonated off Margate at 10:35 am after it was caught up in a fishing vessel's nets.
The controlled explosion about 1.2 miles from the harbour registered with the British Geological Survey (BGS) in Edinburgh.
Numerous calls were received by Thanet council and BBC Radio Kent, from people fearing a repeat of April's earthquake around the coast in Folkestone.
A BGS spokesman said the equivalent magnitude was 2.5 on the Richter scale.
The coastguard spokesman said it was thought the mine, described as an 8ft-long and 3ft-round metal cylinder, could have contained up to a tonne of explosives.
