Indian Plate Movement

The Indian Plate, also prominently known as the India Plate, is part of the world’s eastern hemisphere. India, during the ancient ages, was part of the ancient continent Gondwana. It got separated from the rest of the ancient continent nearly 100 years ago and started shifting towards the north.

The Indian plate majorly includes South Asia and apart from this it also includes a certain portion of the basin beneath the Indian Ocean that includes certain parts of South China and Western Indonesia. It also comprises Kohistan, Balochistan and Ladakh. Let us learn more about Indian Plate Movements in detail!

Indian Plate Movement

The Indian Plate is a major tectonic plate that primarily occupies the Indian Ocean basin but extends northward into the Himalayas, eastward into the Burmese region, and westward into the Arabian Sea. Its movement plays a significant role in shaping the geology and landscape of the Indian subcontinent. Here’s an overview of the Indian Plate movement:

1. Movement Direction: The Indian Plate is generally moving in a northeasterly direction at a rate of approximately 5 to 6 centimeters per year.
2. Collision Boundaries:
   • Northern Boundary: The Indian Plate is colliding with the Eurasian Plate, leading to the uplift of the Himalayas and the Tibetan Plateau.
   • Eastern Boundary: Collision with the Burmese Plateau contributes to the formation of mountain ranges in northeastern India and Southeast Asia.
   • Western Boundary: Subduction occurs along the western boundary with the Eurasian Plate along the Makran coast, resulting in seismic activity and the potential for tsunamis in the Arabian Sea.
3. Tectonic Activity:
   • Subduction: Subduction zones along the western boundary with the Eurasian Plate cause earthquakes and potential tsunamis.
   • Collision: Collision zones along the northern and eastern boundaries with the Eurasian and Burmese Plates lead to the uplift of mountain ranges and seismic activity.
4. Geologic Features Affected:
   • Himalayan Mountain Range: Formed by the collision between the Indian Plate and the Eurasian Plate.
   • Tibetan Plateau: Uplifted due to the ongoing collision between the Indian Plate and the Eurasian Plate.
   • Eastern Ghats and Western Ghats: Geological features influenced by the movement and collision of the Indian Plate with other tectonic plates.
5. Geological Impacts:
   • Seismic Activity: Earthquakes, particularly along collision and subduction zones, affect regions across India and neighboring countries.
   • Mountain Building: Ongoing uplift and formation of mountain ranges, such as the Himalayas and the Western Ghats, shape the landscape of the Indian subcontinent.
6. Environmental Effects:
   • Topographic Changes: Alteration of landforms due to tectonic activity influences habitats, drainage patterns, and erosion processes.
   • Climate Influence: Indirect impacts on regional climate patterns occur due to changes in topography and atmospheric circulation caused by mountain uplift and plate movement.

Indo-Australian Plate

The Indo-Australian Plate is a major tectonic plate that spans a large portion of the Indian Ocean basin and extends into the Australian region. It is one of the largest tectonic plates on Earth and plays a significant role in the geology and tectonics of the Indian Ocean region. Here’s an overview of the Indo-Australian Plate:

1. Composition: The Indo-Australian Plate consists of both continental and oceanic crust. It encompasses the Indian subcontinent, parts of Southeast Asia, and the Australian continent.
2. Movement Direction:
   • Northward: The northern portion of the Indo-Australian Plate, including the Indian subcontinent, is moving in a northerly direction.
   • Eastward: The eastern portion, which includes Australia and neighboring regions, is generally moving eastward.
3. Boundaries:
   • North: The Indo-Australian Plate is bounded by the Eurasian Plate to the north, primarily along the collision zone with the Indian Plate. This boundary is marked by the Himalayan mountain range.
   • West: Along its western boundary, the Indo-Australian Plate is bordered by the Arabian Plate and the African Plate, primarily characterized by transform faults and spreading centers in the Indian Ocean.
   • South: The southern boundary of the Indo-Australian Plate lies along the Antarctic Plate, marked by the Southeast Indian Ridge and the Southwest Indian Ridge.
   • East: In the eastern region, the Indo-Australian Plate is bounded by the Pacific Plate, particularly along subduction zones in the western Pacific Ocean.
4. Tectonic Activity:
   • Subduction Zones: Subduction occurs along the eastern boundary of the Indo-Australian Plate, where it converges with the Pacific Plate, leading to the formation of volcanic arcs and deep-sea trenches.
   • Collision Zones: Collision and convergence with the Eurasian Plate along the northern boundary result in the uplift of the Himalayas and the Tibetan Plateau.
   • Transform Faults: Transform boundaries along the western boundary of the plate, such as the Carlsberg Ridge and the Central Indian Ridge, contribute to seismic activity and crustal movement.
5. Geological Impacts:
   • Mountain Building: Collision with the Eurasian Plate has led to the formation of the Himalayan mountain range and the Tibetan Plateau.
   • Volcanism: Subduction zones along the eastern boundary result in volcanic activity and the formation of island arcs, such as the Sunda Arc and the Indonesian Archipelago.
   • Seismic Activity: Transform faults and subduction zones generate earthquakes in regions surrounding the plate boundaries.
6. Environmental Effects:
   • Landform Formation: Tectonic activity associated with the Indo-Australian Plate influences the formation of diverse landforms, including mountains, volcanic islands, and ocean basins.
   • Natural Hazards: Earthquakes, volcanic eruptions, and tsunamis associated with plate tectonics pose hazards to coastal regions and island communities surrounding the plate boundaries.

Conclusion

The supercontinent Gondwana used to include various countries which are India, Australia and Antarctica around 225 million years ago. Whereas when the pangea broke, India became a big island around the coast of Australia and was separated from the Asian subcontinent by the Tethys Sea. Later when the continental drift started taking place, the Indian plate started moving northwards which resulted in separation from the Australian plate.

This movement of the Indian plate continued over the years and resulted in the collision with the Eurasian plate. The collision of the Eurasian and Indian plate resulted in the formation of Himalayas which took place around 60 million years ago. This movement of the Indian plate is still in process and it is seen that the rate of migration is five centimeters every year whereas Eurasian plate is moving at the speed of 2 centimeters each year. Various earthquakes which have taken place in this region lately are proof that this shifting of the plates is still continuing.
