Scientists discovered two fault lines under London that could trigger a massive earthquake
Two major faults under London
Researchers at Imperial College London have 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 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 the shaking similar to standing on a platform between two passing trains. However, a magnitude 6 earthquake could cause damage to buildings. Dr Ghail, the 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 believed that the energy released through fault lines and quakes could be beneficial but in small doses according to 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 majority of the temples in Greece where on fault lines or near one. Lydia Giannoulopoulou who is doing a 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 organism, hence a bit of geopathic stress can be beneficial but too much over a long time can be harmful.

What are fault lines?
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.
Earthquakes in the UK
In the last week (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.”
