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.[1]

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.[2]

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, being hit by falling bricks and a girl injured by the toppling of tin-plates at Cwmavon. Reports told of bricks falling from chimneys across the city[3] and the Mumbles lighthouse "rocked on its foundations." [4]
