"RECENT EARTHQUAKE
"Why the one recently felt here was not recorded by seismograph.
"For the benefit of those who thought they felt an earthquake on
the afternoon of Sunday a fortnight ago, a Colonist representative has
obtained the following information from the meteorological office upon
the subject: The photograph traced from the seismograph installed in
the basement of the old customs offices, recorded no Less than five
distinct shocks during the week ending Saturday, November 24. The first
shock occurred at 6:28 a.m. on Sunday the 18th, and from the form of
vibration may have originated some hundreds of miles away. The next
occurred at 7:48 and 7:51 A.M. of the same day as two sharp but small
vibrations, and from their appearance seem of local origin Strange (at
least to the uninitiated) the shock felt in the afternoon did not cause
the instrument to move, though it has been conclusively proved that this
instrument is so sensitive that it is constantly recording earthquakes
that occur at all quarters of the globe.
"The cause for this is that the recording part of this instrument
which consists of a long horizontal broom, is suspended pointing exactly
south; therefore should the earthquake waves travel east or west they
cause the broom to swing; where as, as sometimes happens, these waves
travel directly from north or south, when as they pass under this station,
they can only tip the broom up and down, but not sideways. -It so happens
that the Sunday afternoon quake did travel from north or south, for from
further information, it is learned that it was distinctly felt on the
Gorge Road, at the Pacific club, on fort street, and in a house on the
Dallas road., near Menzies street, the time being about 2 o'clock before
the close of the week, no less than three more shocks were recorded and
none of these were of local origin, on the contrary they were of a type
of vibrations whose birth place was probably the other side of the
world." |
