|ORIGIN TIME||11:54:32.2 UTC|
The earthquake of the 11 July 2014 occurred at 11:54 UTC (12:54 BST), with an epicentre approximately 15 km west of Jersey, Channel islands. The instrumental magnitude was determined at 4.2 ML, and the earthquake was located approximately 37 km west of a magnitude 5.2 earthquake that occurred on 12 April 1932. The BGS has received around 100 felt reports from members of the public across the Channel Islands via an automatic online questionnaire survey. Most people described the shaking strength of the earthquake to be moderate, with a trembling effect, and described the sound strength as faint to moderate. Almost all reports stated that windows rattled. Reports described “I thought a plane had crashed nearby”, “everyone in the office noticed it and people in surrounding shops”, “it was one rumble then after a second or two another one of the same magnitude of a second in length, so altogether around 3 to 4 seconds from start to finish” and “sudden like a large impact,.. with a bang / rumble, enough to make you jump and go outside to see what happened”.
Further afield, two felt reports were received from the south coast of England, namely one from Torquay, Devon, and the other from Poole, Dorset. The EMSC has also received many felt reports from the Channel Islands and several felt reports from mainland France, around the coast of the Gulf of St Malo.
