Aire Valley Fault: The Geological History of Yorkshire's Keighley Fault
Deep beneath the landscapes of Yorkshire, England, lies a significant geological feature known as the Aire Valley Fault. Also referred to as the Keighley Fault, this structural break in the Earth's crust provides a glimpse into the tectonic forces that shaped the region. While it is currently classified as an inactive fault, its physical presence continues to influence the surface environment today.
Geological Classification and Connectivity
The Aire Valley Fault is categorized as a strike slip fault, a type of fracture where two blocks of rock slide past each other horizontally. Geologically, it is viewed as the northwestern continuation of the Morley-Campsall Fault Belt. Its trajectory extends northwards from the Huddersfield and Wakefield areas, eventually merging into the South Craven fault.
Furthermore, the system is interconnected with the Denholme Clough Fault, forming a complex network of geological fractures across the West Yorkshire region.
Local Impact and Urban Presence
Although the fault is inactive, its location beneath modern urban developments has led to observable physical effects. The fault line runs directly underneath the Keighley bus station and the Airedale Shopping Centre. The structural instability associated with the fault's path has resulted in the appearance of cracks within the Airedale Shopping Centre.
