Is London Basin fundamentally (by definition) capable of drifting east-west, or only north-south?
No, the London Basin itself cannot drift east-west. The London Basin is a geological structure made up of sedimentary rocks that is relatively stable. The movement of such geological features is generally influenced by tectonic activities, but these movements are typically very slow and occur over geological timescales.
Movement in the London Basin area can be attributed to tectonic plate movements. The Earth's lithosphere is divided into tectonic plates that can move relative to each other. However, the UK is located on the Eurasian Plate, which is not highly active compared to other regions like the Pacific Ring of Fire, hence any movement is minimal and slow.
The stability of the London Basin, like other geological areas, is monitored using various geotechnical instruments and techniques. These include GPS measurements, satellite observations, and seismographic data to track any subtle movements or shifts that may indicate tectonic or human-induced activities.
Historically, there has not been any significant movement of the London Basin that would suggest it can drift east-west. The geological record indicates that the area has been relatively stable since its formation. Minor movements have occurred due to isostatic adjustments (the rise and fall of land after ice ages) and sediment compaction.
If the London Basin were to experience significant movement, it could have various implications including impacts on infrastructure, such as buildings and transportation networks, and potentially on natural resources like groundwater systems. However, such significant movement is highly unlikely given the current geological understanding and tectonic setting of the region.
