Barren Island Volcano that was dormant for 150 years is erupting again in Andaman
In a new study, researchers have
revealed that India’s only active volcano located in the Andaman and Nicobar
islands has started erupting again after being in the dormant state for over
150 years.
According to researchers, the volcano is spewing small amount of
ashes in intervals and might explode massively at any time.
The
Barren Island volcano is located 140 km northeast of Port Blair and was
inactive until 1991, and since then the volcano has erupted in irregular
intervals. Scientists say that the volcano is spewing out ash again and might
create havoc once it starts exploding.
The
activity was first observed by the CSIR-NIO scientists on January 23,
2017. Researchers explained that they were aboard RV Sindhu Sankalp ship
for collecting samples of the sea floor in the Andaman Basin near the Barran
Island volcano when they first spotted it spewing ashes into the sky.
Scientists
were at a distance of nearly a mile from the volcano and started observing the
activity. They revealed that the volcano was erupting in small intervals of
five to 10 minutes which resulted in the formation of clouds made up of ash.
Another team of scientists visited the volcano three days later and found that
it was erupting molten lava streaming down the slopes that was destroying everything
in its path.
Study authors have collected samples of sediments
and water in the vicinity of the volcano and recovered coal-like black
pyroclastic material representing proximal volcanic ejecta. While giving a
statement, scientists said that the clouds are visible at the mouth of the
Barren Island volcano and it is still spitting smoke in the sky. In addition,
the collected samples will help CSIR-NIO scientists in unraveling the
mysteries and nature of the volcano.
Scientists
are studying and observing the nature of India’s only active volcano for past
several years. CSIR-NIO scientists have observed activity of volcano for
at least four years before witnessing the latest eruption. However, no
scientist has ever tried of land on the volcano as it was considered very risky
and dangerous.
