At first look you might consider the
otherworldly light in these pictures comes from a nebula or another planet deep
in outer space or probably you have heard of "red hot lava" or
"white hot" to describe searing temperatures, so but what about
"blue hot lava"? Kawah Ijen is one of several volcanoes located
within the 20 kilometers wide Ijen Caldera in East Java, Indonesia. The caldera
of Kawah Ijen harbors a kilometer-wide, turquoise colored, acidic crater lake
that leaks sulphurous gases constantly. That's the surreal hue of Indonesia's
Kawah Ijen Volcano, which glows with an otherworldly "blue lava".
Normally at night the hot gases burn to
emit an eerie blue glow that is distinctive to Kawah Ijen. These gases emerge
from the cracks in the volcano at high pressure and temperature, up to 600°C,
and when they come in contact with the air, they ignite, sending flames up to
16 feet high. Specific gases condense into liquid sulfur, and continues to burn
as it flows down the slopes giving the feeling of blue lava flowing. Kawah
Ijen’s sulphuric gases are also mined for sulphur. The volcanic gases are
trapped by the native miners and channeled through a network of ceramic pipes,
which in result of condensation of molten sulfur.
The sulfur, normally red in color when
molten, pours gradually from the ends of these pipes and pools on the ground,
turning bright yellow as it cools.
The expert miners break the cooled
material into big pieces and carry it away in baskets to an adjacent refinery.
In this way an expert worker can earn up to $13 dollars a day. Therefore you
can’t imagine the intense heat and extremely hazardous condition with
insufficient protection. Many workers suffer various respiratory problems due
to breathing toxic fumes day in and out. So they’d prefer to work at night to
escape the heat of the sun, and to earn extra income as well. These astonishing
images are captured by photographer Olivier Grunewald, who lost two lenses and
a camera to sulphuric corrosion while trying to capture the mysterious pictures.
