Is London Basin fundamentally (by definition) capable of drifting east-west, or only north-south?

I've a vague recollection that the Eastern part is an 'early' aulacogen related to the faulting and rifting in eg North Sea. This would make it a weak-zone for any tectonic stress, be that lateral or extensional...

You'd have to look at the regional stress-field due African plate's sorta-Northward plus clock-wise progress, and second-order stuff due interposed Iberia / Western Europe getting pushed about / rotated...

At least London Basin need not consider Wilson Cycle subduction zones & consequences for near-future, or even several millennia. IMHO, it is not speculation to say such processes are simply too slow. Should Gibraltar shelf spawn an Atlantic-swallowing trench, would take a geological age before that spreads up coast, or down-goings become volcanic up-comings per Caribbean Arc...

Found the answer. London Basin is able to drift east-west. It is the "average" of Earth crustal plates that must not drift east or west.

1. Can the London Basin actually drift east-west?

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.

2. What causes any movement in the London Basin area?

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.

3. How is the stability of the London Basin monitored?

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.

4. Has there been any significant historical movement of the London Basin?

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.

5. What would be the implications if the London Basin were to move significantly?

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.
