The 1906 Swansea earthquake hit near the town of Swansea, Glamorgan, Wales on 27 June. It was one of the most damaging to hit Britain during the twentieth century, with a small area reaching an intensity of VII on the Medvedev–Sponheuer–Karnik scale.
Location, date and time
[edit]At 9.45am on 27 June 1906, a powerful earth tremor was felt across much of South Wales, its epicentre being placed just offshore of Port Talbot. The quake, which struck just a few weeks after the devastating 1906 San Francisco earthquake, was felt as far afield as Ilfracombe, Birmingham and southwest Ireland.[3]
Cause
[edit]Swansea is located near the southwestern ends of two major fault structures; the Neath Disturbance and the Swansea Valley Disturbance, movement on either of which or on any of several adjoining faults may have caused the quake.
Magnitude
[edit]The magnitude of the earthquake was measured at 5.2 on the Richter scale.
Impact
[edit]The earthquake was felt by many people, though recorded injuries were minimal: a young man, Thomas Westbury, and a three-year-old boy, Thomas Lewis, were hit by falling bricks and a girl was injured by the toppling of tin plates at Cwmavon. Reports told of bricks falling from chimneys across the city[4] and the Mumbles lighthouse "rocked on its foundations."[5]
