The '''1869 Cachar earthquake''' occurred on 10 January with an estimated moment magnitude of 7.4 and a maximum EMS-98 intensity of VII (''Damaging''). Two people were killed and damage was considered severe. The earthquake was felt in [[Upper Burma]], [[Bihar]], [[Jharkhand]], [[Bengal]] and [[Northeast India]].

==Earthquake==
The cause is said to have been from a {{convert|32|km}} long fissure below the [[Jaintia Hills]], situated north of the [[Sylhet region]].<ref>{{cite book|title=Assam District Gazetteers|volume=2|year=1905|location=[[Calcutta]]|author=B C Allen|publisher=[[Government of Assam]]|page=13|chapter=Physical Aspects}}</ref>{{clear}}
