As is often the case , it is not always the strongest earthquakes that cause the most damage , and the British Geological Survey estimates that the 1884 earthquake 's magnitude was only around 4.6 on the Richter magnitude scale , compared with 6.1 for the 1931 Dogger Bank earthquake . Langenhoe Church was badly damaged . Masonry tumbled off the tower , crashing into the roof of the nave and chancel . The nearby rectory was also damaged
