|ORIGIN TIME||18:36:08.7 UTC|
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.”.
