CHAPTER VJ. 
THE AREA ENCLOSED BY ISOSEIST No. 6. 
The area enclosed by Isoseist No. 6 is the area where the earth- 
quake was only felt by certain people and where no damage was 
done to buildings of ordinary strength or stability. The inform- 
ation regarding it is all derived from information supplied by 
observers or on earthquake enquiry-forms. It is not proposed to 
give a detailed list of the observations received from all the places 
in this area but only to give those which have been made use of 
to fix the position of Isoseists Nos. 5 and 6. 
The most important are : — 
Allahabad. — The Collector of Allahabad. — Only one member of my staff 
noted the earthquake. The pLice was the Manjhanpur Tahsil where the 
tahsildar noticed the earthquake while in court. It occurred at eight or 
ten minutes to four in the afternoon and the oscillations seemed to be east 
and west. No objects were overturned and the shock was only felt by 
him, his Tahsili 8iahana^vis and the Sentry standing at the Sub-Treasury. 
Agra. — The Commissioner of Atjra. — The exact time of the earthquake was 
not noted. The shock lasted about li seconds. During the shock the 
woodwork of doors creaked. The shock was not felt by everyone. 
Bankipore.— 27je Collector of Patna. — Tlie earthquake was felt at Banki- 
pore only by people sitting or standing still in a room. No objects were 
overturned. 
BiLASPUR. — The Depuly Commissioner. — The shock was felt by a number 
of people, the exact time was not noted. No objects were overturned, but 
the padlock on an almirah rattled. 
Calcutta. — The earthquake was felt by nearly everyone. Only people 
who were walking or moving out of doors did not feel it. The following 
extract is taken from a report of the shock published by the newspapers 
next morning : — 
Report by the Meteorological Observatory at Alipore. — " The earthquake 
shock was a local shock of considerable intensity. It was recorded 
on the Alipore seismograph at 15 hours, 53 minutes, standard time, 
or 4 hours 16 minutes, Calcutta time. It must have occurred at 
a comparatively short distance from Calcutta. The oscillation 
was so large that the seismograph recording pens were thrown 
completely off the recording drums. The severe oscillation continued 
for more than five minutes and at five-thirty the seismograph 
was still recording a small oscillation.
