Mw 7.9 Kyelang, India
updated 9 August 2021

On 4 April 1905 a major earthquake occurred at Kyelang, India at a depth of 20km. The seismic event occurred at 00:49:59 UTC and had an estimated moment magnitude (Mw) 7.9.

During 1905 and 1906 Earth repeatedly came closely between Uranus and Neptune, which at the time were on opposite sides of the Solar System. While no other planetary alignments occurred, the Moon made critical geometry to both Uranus and Neptune within a few hours on 31 March and on 4 April 1905. Often when this happens, large seismic activity occurs, ranging from higher 7 to 8 magnitude, depending on the amount of fault stress and where it is critical. See also the 1906 archive for similar reports.
