from below, the action somewhat resembling in effect the feeling one 
might experience if the floor on which one was standing were sub- 
jected to a hard blow from underneath. This was apparently followed 
by a rapid motion from side to side, and finally by a tortional motion 
which is described as shaking objects much as a terrier shakes a rat. 
It was this motion which produced the twisting exhibited by nearly all 
statues in the city (Fig. 2). As already indicated, there were three 
or more maxima of intensity during the shock. A feeling of intense 
confusion was experienced by those feeling the shocks but nausea 
was seldom produced. 
Intensity and amplitude of the vibrations —The amplitude of the 
vibrations appears to have been small. Only in occasional instances 
were street cars shaken from the tracks, few of the statues were over- 
turned, and only a small number of telegraph, telephone, or trolley 
poles were overthrown or tilted. This would hardly have been 
the case if the lateral movement had been considerable. As nearly as 
can be judged from descriptions the movement was not over an inch. 
The intensity of the shock, as attested by the ruins, however, 
was very high, the destructions being to a considerable extent due 
to a sort of disintegration, apparently resulting from very strong and 
rapid vibrations, which, however, were of short amplitude, at least 
in the rock areas and the stiff semi-compacted alluvium of the Kings- 
ton region. 
ASSOCIATED PHENOMENA 
Noise.—The earthquake was accompanied by a loud noise, de- 
scribed as a deep crushing sound, somewhat suggesting distant thunder 
but with less boom and more of a roar. Intermixed with the natural 
sounds proceeding from the earth was the crashing of the buildings 
and the cries of the people, the two together being described as almost 
deafening. 
Dust.—One of the phenomena described by all eye-witnesses was 
the notable darkness following the shock. The local mortar, rather 
poor at the best, which was used in most of the buildings, pulverized 
quickly, and was projected into the air together with other dust 
in immense quantities as the buildings fell, saturating the atmosphere 
until it was almost impenetrable to the suns rays. After the cessation
