Which tectonic plates cause earthquakes in India?

Which tectonic plates cause earthquakes in India?

The Indian plate’s collision with the Eurasian plate causes earthquakes in the Himalayas in north India, the Indo-Burmese arc in northeast India and in the Andaman-Sumatra region in the Andaman Nicobar island belt.

What type of fault is the Indian Plate?

Geography. The westerly side of the Indian Plate is a transform boundary with the Arabian Plate called the Owen Fracture Zone, and a divergent boundary with the African Plate called the Central Indian Ridge (CIR).

What is Indian Plate and Burma plate?

The Burma Plate is a minor tectonic plate or microplate located in Southeast Asia, sometimes considered a part of the larger Eurasian Plate. To the west is the much larger India Plate, which is subducting beneath the western facet of the Burma Plate. This extensive subduction zone has formed the Sunda Trench.

What tectonic plates can cause earthquakes?

Movement in narrow zones along plate boundaries causes most earthquakes. Most seismic activity occurs at three types of plate boundaries—divergent, convergent, and transform. As the plates move past each other, they sometimes get caught and pressure builds up.

Where is the Indian tectonic plate?

The Indian tectonic plate is located in the north east hemisphere. It is bounded by 4 major tectonic plates. North of the Indian plate is the Eurasian plate, to the south east, the Australian plate, to the south west, the African plate and to the west the Arabian plate.

Is Indian plate a continental plate?

80 Ma India was 6,400 km south of the Asian continent but moving towards it at a rate of between 9 and 16 cm per year. At this time Tethys Ocean floor would have been subducting northwards beneath Asia and the plate margin would have been a Convergent oceanic-continental one just like the Andes today.

Which is the largest tectonic plate?

A tectonic plate (also called lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere. Plate size can vary greatly, from a few hundred to thousands of kilometers across; the Pacific and Antarctic Plates are among the largest.

What caused the Indian plate to move?

The rifting is thought to be caused by the rising of a mantle plume which caused the Indian plate to drift northwards and resulted in the opening of the Indian Ocean. The velocity of the drifting of the Indian plate northwards was surprisingly high, 18 to 20 cm per year prior to the collision with the Eurasian plate.

What plate does not have earthquake?

Antarctica has the least earthquakes of any continent, but small earthquakes can occur anywhere in the World.

Why are there so many earthquakes in Indiana?

Indiana earthquakes that occurred during the last 200 years are the result of movement along faults that are more than 6 miles below the surface. Because these faults are so deep, combined with the nature of rock layers at depth, it is difficult for seismologists to successfully map earthquake-generating faults using remote-sensing techniques.

Which parts of India have experienced the most earthquakes?

Himachal Pradesh, Uttaranchal, Sikkim, and the Darjiling and subdivision of West Bengal and all the seven states of the northeast. Apart from these regions, the central-western parts of India, particularly Gujarat (in 1819, 1956 and 2001) and Maharashtra (in 1967 and 1993) have also experienced some severe earthquakes.

How are fault lines mapped in Indiana?

Researchers have mapped some faults in Indiana using evidence found in oil and gas wells and in outcrops, but they also employed a method called seismic reflection profiling, which creates images of the rock layers below the Earth’s surface. Many of the mapped faults in Indiana are in the southwestern corner of the state.

Why are the Indian and Eurasian plates locked with each other?

The Indian plate is moving at a speed of one centimeter per year towards the north and northeastern direction and this movement of plates are being constantly obstructed by the Eurasian plate from the north. As a result of this, both the plates are said to be locked with each other resulting in accumulation of energy at different points of time.
