Scientists discovered two fault lines under London that could trigger an earthquake
Two major fault lines in London
The feng shui of London is very good. However, in 2018, researchers at Imperial College London found two fault lines running under London that could potentially cause a magnitude 5 earthquake. These fault lines move between 1mm and 2mm every year. The faults run directly under central London and under Canary Wharf. The researchers were using Persistent Scatterer Interferometric Synthetic Aperture Radar (PSInSAR) and believe that London is overdue for a quake but suggest that there is a one-in-a-thousand-year chance of a tremor. “The faults were initially inferred from geomorphology – drainage patterns, etc. – [along with] borehole records, and site visits,” Ghail told IFLScience. He noted, though, that they “detected their motion using satellite Persistent Scatterer Interferometry (PSI) radar data,” a technique that tracks even small changes in displacement over time.
The last large earthquake in London happened on the 6th of April 1580, and it had a comparably large magnitude 5.5. A magnitude 5 earthquake is comparable to shaking, similar to standing on a platform between two passing trains. However, a magnitude 6 earthquake could cause damage to buildings. New buildings in London will be made so they can withstand a quake registering 6.5 on the Richter Scale. Dr Ghail, a researcher at Imperial College London, said the greatest risk to Londoners is not the earthquake itself but the knock-on effects.
Geopathic stress and fault lines
Research in geopathics and geobiology suggests that geopathic stress can be caused by fault lines. Traditionally, in many cultures, people tried to avoid building or living over fault lines for obvious reasons. Having said that, some of the most famous sacred places and temples are built over fault lines because people believe that the energy released through fault lines and quakes could be beneficial but in small doses, according to the hormesis theory. Igor V Florinsky (2010) looked at 104 monasteries and almost all of them were located along fault lines and intersections of them. Another researcher Farmaki (2013), identified that the majority of the temples in Greece were on fault lines or near one. Lydia Giannoulopoulou, who did her PhD on this subject, suggests that “most basic characteristic of ancient monuments and temples is the concentration of natural geomagnetic and electric fluctuations.” The theory of hormesis states that the same external agent can cause low-dose stimulation and high-dose suppression on living organisms; hence a bit of geopathic stress can be beneficial, but too much over a long time can be harmful.

London earthquake risk. Where are the fault lines in London?
In geology, a fault line is a crack or discontinuity in the Earth’s surface, along which movement and displacement that take place there. The energy released by the movement on the active fault lines is what causes most earthquakes. Faults don’t usually consist of a single fracture, so the term ‘fault zone’ refers to the area where deformation is correlated with the fault plane. In many parts of the world, it is prohibited to build near faults (California, Japan), where earthquakes are a regular hazard and can damage the infrastructure and lead to injuries and death. The researchers at Imperial College London revealed that the subterranean fault lines shift between 1 and 2 mm every year. Dr Ghail, a civil engineering specialist at Imperial College, talking about the chances of a magnitude five earthquake, said it’s ““enough to be scary but not fundamentally a problem”.
London’s two major fault lines go through central London and under Canary Wharf.
Earthquakes in the UK
The UK is not known for earthquakes, but the British Geological Survey (BGS) reminds us that they do occur – hundreds of small ones take place each year, but mainly on the western side of the British mainland. The largest occurred in 1931, some distance offshore, registering as a 6.1M tremor.
In the week of 27-30 June 2018, there were two earthquakes of a magnitude of 2.4 and 2.6 in Surrey for the first time in 40 years. There is a “constant stream” of small earthquakes all over the UK on regular bases, says Richard Luckett, a BGS seismologist. There are concerns that fracking can cause the quakes, and Mr Luckett said, “It is plausible, as fracking can cause earthquakes.”
“Prevention is better than cure.”

Earthquakes and volcanos in the world
Other countries have more seismic activity as well as volcanic activity. For example, Iceland is a very volcanic country, and earthquakes accompany volcanic eruptions. When I visited the country as a feng shui consultant and environmental psychologist to evaluate feng shui of Reykjavik and Iceland, researchers were very clear that there would be more volcanic activity there because the glaciers are melting, and this activates the volcanos.
