The Hidden Volcanoes of Andaman: Nature’s Fiery Treasures
When we think of the Andaman Islands, we imagine bright sunny beaches and beautiful coral reefs. What you may not know is that this wonderful paradise has among the most beautiful volcanic landscapes in the world. There are over 1500 active volcanoes across the world, and the Andaman Islands happen to host some of them. Active lava domes and dormant giants form the fiery world of the Andaman Islands, which makes it a unique experience. 

Exploring these volcanoes will undoubtedly be a rare adventure in your itinerary. Let’s read about the volcanoes in Andaman that are sure to ignite your curiosity.

Geological Formation of the Andaman Islands

The Andaman Islands were formed through volcanic activities by the movement of tectonic plates for millions of years. This has given rise not only to today’s islands but also to the active environment flourishing here. 

Geological Background. 

The Andaman Islands have emerged as an island chain in the Indian Ocean, born out of volcanic action. Located within a convergent boundary between the Indo-Australian and Eurasian tectonic plates, these islands lie along a narrow zone known for its seismic activity. It was that pressure from the tectonic movements that broke the earth’s crust over millions of years to give rise to volcanic eruptions that slowly built the islands we see today. So, next time you step onto the beaches in Andaman, remember that the volcanic legacy of the island is as important as the coastal beauty.

Role of Volcanoes in Shaping the Landscape

Along with shaping landmasses, volcanic eruptions influence the wet, lush landscapes that characterize the Andaman Islands. There have been rich soils formed due to lava flows, ash deposits, and geothermal activity, leading to dense tropical forests and unique ecosystems. The mud volcano in Andaman is only one example of how many of such volcanoes in Andaman are still shaping the land today and developing a biodiversity as rich on land as well as under the sea.

Barren Island: The Only Active Volcano in India

Barren Island lies about 135 kilometers northeast of the main Andaman Islands. It is a mystery and a wonder. It is India’s only active volcano in the Andaman, the very few active volcanoes are found in the Indian Ocean. Barren Island is true to its name since it is largely uninhabited. For 

Adventure lovers, this island does not disappoint and is a gem in the Andaman itinerary for 5 days

Volcanic Activity and History 

Barren Island has erupted from time to time over the past few decades, the last of which was in 2017. The active lava emits smoke now and again, making it a reminder of the island’s fiery heart. Barren Island volcano is an extraordinary sight that makes it stand as India’s only active volcano in the whole world.

Why It’s a Hidden Gem

Because it lies in a protected area and can be visited only by special permits, it is considered to be one of the most hidden treasures of the Andaman Islands. It is perfect if you are seeking a special adventure and especially for those on an  Andaman tour package.

Barren Island has geothermal hot springs. You can take a soothing journey to the hot springs scattered across the islands! Bathing in hot springs is said to be therapeutic, with water heated by volcanic activity below the surface. Treks and boat excursions in such areas present an alternative way to indulge the volcanic past of the Andaman Islands. 

Dormant, Yet Enthralling: Narcondam Island

East of the Andaman Islands lies Narcondam, another volcanic spectacle. The volcano here, in contrast to Barren Island, is dormant but enthralling. Narcondam is famous for its amazing biodiversity and is a hotspot for naturalists, particularly bird watchers and divers. The dormant volcano here in Andaman captivates attention as one of the best-kept secrets of the archipelago. 

Unique Features of Narcondam Volcano

Rainforests blanket Narcondam dormant volcanoes, which shelter rare species such as the endemic Narcondam hornbill. Rugged cliffs and craters tell the volcano’s tale. The underground workings of the Narcondam volcano ensures that the soil is enriched, sustaining a lush forest. 

Access and Exploration

Except during the monsoon season, Narcondam Island has been banned from tourism most of the year. Nonetheless, divers and guided tours can be arranged to explore the surrounding waters and land. Visibility around the island is spectacular, allowing divers to explore the volcanic seabed and glorious marine life.
