Kerala, often referred to as "God's Own Country," has a rich historical and cultural heritage. Its origin is explained through both geological and mythological perspectives. The geographical formation of Kerala, including its unique coastline, is a fascinating tale interwoven with scientific theories and folklore. This article delves deep into these aspects to provide a comprehensive understanding of Kerala's origin.
Geological Perspective
1. Tectonic Plate Movements
The Indian subcontinent, including Kerala, is a result of the collision between the Indian and Eurasian tectonic plates.
The Western Ghats, which run parallel to Keralas coastline, were formed due to this collision and subsequent uplifting during the Mesozoic Era.
The low-lying areas of Kerala, including its coastal plains, were shaped by sedimentation and erosion caused by rivers originating in the Western Ghats.
2. Marine Transgression and Regression
Kerala's coastline has undergone significant changes due to the rise and fall of sea levels over millions of years.
Geological evidence suggests a series of marine transgressions (inundation by seawater) and regressions (retreat of seawater), shaping its unique coastal morphology.
3. Formation of Laterite Soils
The laterite soils, prominent in Kerala, were formed due to intense tropical weathering over millennia.
These soils contribute to the states lush vegetation and agricultural richness, playing a significant role in its geography.
4. Riverine Deposition
Major rivers like the Periyar, Bharathapuzha, and Pamba played a crucial role in shaping Keralas plains through alluvial deposits.
The deltas formed by these rivers also contributed to the extension of the coastline.
Mythological Perspective
1. The Legend of Parasurama
According to Hindu mythology, Kerala was created by Lord Parasurama, the sixth avatar of Lord Vishnu.
Parasurama is believed to have thrown his axe into the sea, commanding the waters to retreat, which led to the creation of the land that is now Kerala.
This mythological tale is deeply embedded in the states cultural consciousness and is often referenced in traditional ceremonies and festivals.
2. Connection to the Ramayana
Kerala finds mentions in the epic Ramayana. It is said that Lord Rama crossed the Pampa River during his search for Sita, linking the states rivers to divine lore.
3. Cheraman Perumal Tradition
Another myth involves Cheraman Perumal, the legendary ruler of Kerala, who is said to have divided the land among his chieftains. This tale is symbolic of the regions historical feudal setup.
4. Asura and Deva Conflict
Myths also narrate the conflicts between Asuras (demons) and Devas (gods) over Kerala, emphasizing the land's sacred and strategic importance in ancient lore.
Formation of Kerala's Coastline
1. Geological Processes
River Discharge: Rivers originating from the Western Ghats transported sediments to the Arabian Sea, creating extensive alluvial plains along Kerala's coastline.
Wave and Tidal Action: The interplay between waves, tides, and sedimentation further molded the intricate structure of Keralas backwaters and estuaries.
Sea-Level Changes: Fluctuations in sea levels, particularly during the Holocene epoch, contributed to the shaping of Kerala's coastal features.
2. Natural Disasters and Geological Events
Erosion and Deposition: Coastal erosion caused by monsoonal storms and wave action continues to redefine the shoreline.
Tsunamis and Tectonic Activity: Historical records and studies suggest that tsunamis and undersea earthquakes may have influenced the coastline.
3. Formation of the Backwaters
Keralas iconic backwaters, including Vembanad Lake, were formed due to the deposition of sediments that created a natural barrier parallel to the coast.
The lagoons and interconnected canals are a result of centuries of sediment deposition and tidal action.
4. Human Interventions
In the medieval period, humans
