One of the two alternate fault plane solutions determined in this study for the Koyna earthquake of 1967 December 10 shows a component of normal faulting. This possibility remained unnoticed in previous focal mechanism studies. Both solutions show left lateral motion along the nodal plane striking towards north‐north‐east. The origin of the tectonic stress causing the earthquake is believed to be related to the collision of Indian and Eurasian continents, following which the entire Indian Peninsula may be under a state of left lateral shear.
