The earthquake which took place in Assam, June 12, 1897, was described
by Mr. R. D. Oldham in the British Association as having been the most
violent of which there is any record. The shock was sensible over an
area of 1,750,000 square miles, and if it had occurred in England, not
a house would have been left standing between Manchester and London.
Landslips on an unprecedented scale were produced, a number of lakes
were formed, and mountain peaks were moved vertically and
horizontally. Monuments of solid stone and forest trees were broken
across. Bridges were overthrown, displaced, and in some places thrust
bodily up to a height of about twenty feet, and the rails on the
railroads were twisted and bent. Earth fissures were formed over an
area larger than the United Kingdom, and sand rents, from which sand
and water were forced in solid streams to a height of three or four
feet above the ground, were opened "in incalculable numbers." The loss
of life was comparatively small, as the earthquake occurred about five
o'clock in the afternoon, and the damage done was reduced by the fact
that there were no large cities within the area of greatest violence;
but in extent and capacity of destruction, as distinguished from
destruction actually accomplished, this earthquake surpassed any of
which there was historical mention, not even excepting the great
earthquake of Lisbon in 1755.
The first section of the electric railway up the Jungfrau, which is
intended to reach the top of the mountain, was opened about the first
of October, 1898. The line starts from the Little Scheidegg station of
the existing Wengern Alp Railway, 6,770 feet above the sea, and
ascends the mountain masses from the north side, passing the Eiger
Glacier, Eiger Wand, Eismeer, and Jungfraujoch stations, to Lift,
13,430 feet, whence the ascent is completed by elevator to the summit,
13,670 feet. The road starts on a gradient of ten per cent, which is
increased to twenty per cent about halfway to the Eiger Glacier
station, and to twenty-five per cent, the steepest, after passing that
station. There are about 85 yards in tunnel on the section now opened,
but beyond the Eiger Glacier the road will not touch the surface
except at the stations. About 250 yards of the long tunnel have been
excavated so far. The stations beyond Eiger Wand will be built within
the rock, and will be furnished with restaurants and beds. At the
Eiger Wand and Eismeer stations passengers will contemplate the view
through windows or balconies from the inside; but at the Jungfraujoch
station tourists will be able to go out and take sledges for the great
Aletsch Glacier. The cars will accommodate forty passengers each, and
the company expects to complete the railroad by 1904.
