🔆Ashtamudi Lake
✅It is located in the Kollam district of Kerala.
✅The lake is fed by the major river, Kallada.
✅The name “Ashtamudi” means “eight coned” in Malayalam, referring to the shape of the lake, which resembles a set of eight small channels.
✅The lake is connected to the Arabian Sea through the Ashtamudi Estuary.
✅It is part of the Ashtamudi Wetland, which is a Ramsar Wetland site, recognized in 2002 for its international importance.
✅Ashtamudi Lake faces challenges such as pollution, encroachment, and the impact of climate change.
✅Efforts are being made to preserve its ecological balance through conservation initiatives.

✅The river joins the Brahmaputra in Bangladesh before it flows into the Bay of Bengal after meeting with the Ganges and the Meghna.
✅Two major large barrages constructed on Teesta –
🔸Gajoldoba in West Bengal, India
🔸Duani in Bangladesh.
Major Tributaries of Teesta River
✅Left-bank Tributaries: Lachung Chhu, Chakung Chhu, Dik Chhu, Rani Khola and Rangpo Chhu.

🔆Lake Prespa
✅According to experts, of the 450 hectares of Little Prespa Lake in Albania, at least 430 hectares have been transformed into swamps or dried up.
✅It is one of the oldest tectonic lakes in Europe, and also the highest tectonic lake on the Balkan Peninsula.
✅It lies at the junction of three major geological masses: a granite massif on the East, a karstic massif belonging to Galicica on the West, and the Suva Gora on the South.
✅The region is famous for having rocks from the oldest Paleozoic form to sediments belonging to the young Neogene era.
✅It is made up of the Great Prespa Lake (Albania, Greece and the Republic of Macedonia) and Small Prespa Lake.

🔆Kopili fault zone
✅Recently, researchers from the Indian Institute of Geomagnetism (IIG) have identified seismogenic liquefaction features in the active Kopili Fault (KF) zone.
✅It is a 300 km long and 50 km wide lineament situated in the northeastern region (NER) of India.
✅It extends from the western part of Manipur to the tri-junction of Bhutan, Arunachal Pradesh, and Assam.
It is closer to Himalayan Frontal Thrust.
✅This is a seismically active area falling in the highest Seismic Hazard Zone V.
✅It is associated with collisional tectonics because of the Indian Plate subducting beneath the Eurasian Plate.
✅The fault itself is a transpressional fracture that generates lower crustal dextral strike-slip earthquakes.
✅A tectonic depression filled up by the alluvium of the Kopili river and its tributaries, the Kopili fault zone has witnessed many seismic activities in the past including the 1869 earthquake (7.8 magnitude) and the 1943 earthquake (7.3 magnitude).
