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.
