| DATE | 03/07/2014 |
| ORIGIN TIME | 18:36:08.7 UTC |
| LOCATION | 56.822 -5.256 |
| DEPTH | 5 km |
| MAGNITUDE | 2.9 |
| LOCALITY | FORT WILLIAM,HIGHLAND |
The earthquake of the 3 July 2014 occurred at 18:36 UTC (19:36 BST), with an epicentre approximately 10 km west of Fort William, Highland. The instrumental magnitude was determined at 2.9 ML, and the earthquake was located approximately 3 km east of a magnitude 3.0 earthquake that occurred on 10 December 2005. Almost 220 felt reports from an automatic online questionnaire survey have been received from members of the public, almost all of them coming from within a 20 km radius of the epicentre, in particular from the relatively more densely populated areas of Fort William, Spean Bridge, Kinlochleven, Ballachullish and the hamlets on the eastern shore of Loch Lihnne. Further afield, reports have been received from the Loch Hourn and Loch Nevis areas (35 km to N and NW of epicentre), Acharacle (35 km to W of epicentre), Lochaline (45 km to SW of epicentre), the Isle of Lismore 34 km to WSW of epicentre), and just south of Oban (63 km S of epicentre) (see map).
Most people described the shaking strength of the earthquake to be moderate, with a trembling effect, and described the sound strength as moderate to loud. Many reports stated that windows rattled. Reports described “one second loud rumble followed by sound like thunder and crockery on welsh dresser rattled”, “rumble approaching, then impact felt, then rumble going away”, “sounded like an explosion. Brief shake of building such as caused by quarry blasting”, “vibration on floor with audible rumble which got progressively louder”, “the floor shook so much and you could hear the house rattle and an shake around us” and “it felt like a big explosion underneath the property which seemed to lift and drop it.”.

The instrumental magnitude was determined at 4.3 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.
