A single series of vibrations, accompanied by sounds like those of wind 
and a heavy body falling, was felt at Red Carr. 
(114) 1912, January 28, 5.25 p.m. 
A rather strong shock, accompanied by a loud noise, was felt at Red 
Carr. 
(115) 1912, January 30, 5.25 p.m. 
A shock (intensity 4), consisting of a single series of vibrations lasting 
for two or three seconds, was felt at Menstrie. A sound like loud thunder 
followed the shock. 
(116) 1912, January 31, 5.29 p.m. 
A slight shock (intensity 3), accompanied by a noise like that of a 
prolonged explosion or the distant firing of a cannon, was felt at Dunblane. 
A very loud sound was heard at Menstrie. 
(117) 1912, February 1, 5.25 p.m. 
A shock (intensity 4), accompanied by a loud sound, was felt at Alva. 
(118) 1912, February 9, 1.23 p.m. 
Two vibrations (intensity 4), followed by tremulous motion, were felt 
at Alva. The sound was heard at Alva and Menstrie. 
(119) 1912, February 9, 1.32 p.m. 
The shock (intensity 5) was felt at Alva, Coalsnaughton, Dunblane, 
Logie, and Menstrie. The disturbed area towards the south and west 
was probably bounded by a curve coinciding nearly with the isoseismal 
6 of the earthquake of September 21, 1905, but not extending quite as 
far to the east as that isoseismal. It must therefore have contained 
somewhat less than 80 square miles. The shock consisted of a single 
series of vibrations, and lasted two or three seconds. The sound was 
compared to dull thunder, a heavy body falling, and an explosion in a 
quarry. 
(120) 1912, February 9, 1.39 p.m. 
A very slight bumping noise, like an echo of that which accompanied 
the preceding shock, was heard by many people at Menstrie. 
(121) 1912, February 11, 3.45 a.m. 
A slight tremor (intensity 3), and accompanied by a sound like that 
of the fall of a heavy body, was felt at Alva.
