A mild earth tremor, estimated by the geophysical institute of the Bulgarian Academy of Sciences at 2.6 magnitude on the Richter scale, was registered 31km southwest of Bulgarian capital Sofia on September 14.
The tremor was felt at 2.32pm local time (11.32pm GMT) and its epicentre was at a depth of two km, data from the institute’s earthquake tracking database showed.
