India's and South Asia's only Active Volcano Barren Island errupts
=======================
Barren Island is an island located in the Andaman Sea and is the only active volcano in South Asia. The small 3-km-wide island contains a 1.6-km-wide crater and lies about 138 km northeast of the Andaman Island's capital, Port Blair. To the north of Barren Island 140 km away lies one more important dormant volcano in Indian subcontinent named as Narcondam. So what are the Volcano's of India (Refer the list in the images).
When are the past eruptions
-------------------
The first recorded eruption of the Barren Island volcano dates back to 1787. Since then, the volcano has erupted more than ten times, further eruptions were recorded in 1789, 1795, 1803–04, and 1852. After nearly 150 years of dormancy, the island had another eruption in 1991, 1994–95, 2005–07, 2008-09, 2010-11, 2015 and with the most recent one being in 2017.
Low Visibility
-------------------
As the name suggests the island is totally barren except for a few trees on the coast line. There are some wild goats which inhabit the island. It’s a wonder that these goats live on sea water or may be there are some fresh water springs. A few of them even survived the volcano eruption of 1991. Barren Island has restricted public access and can be reached by Indian Navy or Indian Coast Guard vessels. Private citizens of India can visit the volcanic island by chartered boats after obtaining permission of the Forest Department in Port Blair. Geological Survey of India (GSI) have been studying the volcano for nearly two decades; however, with rare exceptions their studies have been published as the GSI’s internal reports and as conference abstracts are not easily accessible. The volcano has therefore had quite low visibility internationally. There is also no continuous monitoring of the volcano.
2017 Eruption
----------------
A team of scientists led by Abhay Mudholkar, from CSIR-National Institute of Oceanography (CSIR-NIO) in Goa reported that the volcano is active and spewing smoke and lava once again. “On the afternoon of January 23, 2017, the scientific team on board CSIR-NIO’s research ship RV Sindhu Sankalp was busy collecting sea floor samples in the Andaman Basin near the Barren volcano when it suddenly started spewing ash,” the NIO has said.“The team moved about one mile from the volcano and began closely observing it. It was erupting in small episodes lasting about five to ten minutes,” said the release. During the daytime only ash clouds were observed. However, after sundown, the team observed red lava fountains spewing from the crater into the atmosphere and hot lava flows streaming down the slopes of the volcano, it said. NIO has said the volcano was revisited in the early hours of January 26, 2017 again during the second leg of the cruise led by B Nagender Nath, adding the team witnessed the continuation of spurts of blasts and smoke.
