Soufrière, on the island of St. Vincent, had a great eruption on May
7th, 1902, one day before the awful eruption of Mt. Pelée. No lava
flowed during this eruption. There were, however, great discharges
of mud, due to a lake that before the eruption filled the top of
a depression known as the old crater which lay southwest of a new
crater, or the crater that was formed during the eruption of 1812. The
old crater was nine-tenths of a mile across from east to west, and
eight-tenths of a mile from north to south. The depth to the crater
floor was from 1,000 to 2,400 feet. The surface of the new and shallow
boiling lake which occupied the deepest part of the floor during the
latter part of May, and from June to August, was estimated to be
only 1,200 feet above the level of the sea. The sheet of water that
occupied it before the eruption being several hundred feet higher.
Soufrière did not fail to give warnings of its coming eruption.
Rumblings were heard two days before the explosion. On May 5th, 1902,
fishermen who crossed the lake noticed that the water was disturbed
and agitated. On the Tuesday following, May 6th, great clouds were
thrown out during the afternoon, and the volcano was illumined by a
reddish glare of fire. The first explosion was heard shortly before
two o'clock on the following day and the volcano burst into activity.
The explosions, together with great discharges of pumice, ashes, and
boulders, followed one another rapidly. A column of steam was shot up
into the air for a height of 30,000 feet. The severest paroxysm came
shortly after ten A. M., and was succeeded by others nearly
as violent during the next few hours. By this time a reddish curtain
of clouds nearly shut out the island from view, and rapidly advanced
over the land and descended on the sea. This eruption caused a loss of
life of about 1,350.
This eruption of Mt. Soufrière was accompanied by the same tornadic
blast of glowing air. There was not, however, any single blast quite
as severe as that which attended the eruption of Pelée on May 8th,
1902.
CHAPTER XII
SOME OTHER NOTED VOLCANIC MOUNTAINS
Since the limits of our book will prevent any further description
of volcanic districts or regions, we must content ourselves with
descriptions of some of the noted of the remaining volcanoes, although
many we will thus omit contain great wonders.
As we have already seen from the description of Krakatoa, the island
of Java near which Krakatoa is situated is especially noted not only
for the great number of its volcanic mountains, but also for the
frequency and severity of their eruptions.
