🅾️Topics : Gamma Rays /Monazite Sand/IAEA /Basaltic Vocanic Rocks /Uranium Thorium Deposits
🔵Background Radiations or those that are emitted from natural resources like rocks, sands or mountains are nearly three times more than what is been assumed pan India by BARC
✅️It is because of monazite sands that are high in thorium. Moreover, southern India has presence of granite and basaltic volacnic rocks, which have high levels of radiation from Uranium Deposits
* Sievret or nano Gray per hour (nGy/hr)are units to measure radiations emitted from atomic energy establishments✅️

💥India’s only mud volcano at Baratang island (A&N islands) got erupted after 20 years.
[ Topic : Geography ]
👉On October 2, 2025, the mud volcano at Jarwa Creek, Baratang Island (Andaman & Nicobar Islands) erupted violently after being dormant for more than 20 years.
•It was accompanied by a “deafening sound” like an explosion.
•An earth mound of about 3-4 metres high was formed. Mud, water, gases, and smoke spread over an area of more than 1,000 square metres.
👉Geological Context & Causes :
•Baratang Island contains India’s only known mud volcanoes.
•These volcanoes are different from magmatic (lava) volcanoes: they erupt mud, water, and gases (often methane, hydrogen sulfide), rather than molten rock.
•The eruption is thought to have been triggered by tectonic movement – the Andaman & Nicobar region lies in a seismic/tectonic zone, so underground movement (shifting plates, pressure changes) can disturb sediment layers and release gas/mud.
👉Significance :
•This is the first major eruption in about 20 years (last such big eruption ~2005) at this site.
•It highlights how even long-dormant geological features can become active again due to underlying earth processes.
•For both science and tourism: Baratang’s mud volcano is a draw for visitors; this event may lead to more geological studies to understand seismic risks, gas release, sediment behaviour, etc.
•Environmental/Health implications may arise from gas emissions (e.g. methane, hydrogen sulfide) and ground instability; monitoring will be important.
