2001 Gujarat Earthquake
The 2001 Gujarat earthquake, also known as the Bhuj earthquake, occurred on 26 January at . The epicentre was about 9 km south-southwest of the village of Chobari in Bhachau Taluka of Kutch district in Gujarat, India. The earthquake had a maximum Mercalli intensity of XII (''Extreme''). The intraplate earthquake measured 7.6 on the moment magnitude scale and occurred at a depth of . The earthquake killed at least 20,023 people, injured another 166,000 and destroyed about 400,000 buildings in Gujarat, India and Sindh, Pakistan. The vast majority of deaths and damage were observed in Kutch district, while nearly 1,600 additional deaths occurred in the cities of Ahmedabad, Rajkot, Jamnagar, Surendranagar, Surat, Gandhinagar and Vadodara. Tectonic setting Gujarat lies 300–400 km from the plate boundary between the Indian plate and the Eurasian plate, but the current tectonics are still governed by the effects of the continuing continental collision along this bo ...

Fault (geology)
In geology, a fault is a Fracture (geology), planar fracture or discontinuity in a volume of Rock (geology), rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust (geology), crust result from the action of Plate tectonics, plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction, subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep. A ''fault plane'' is the Plane (geometry), plane that represents the fracture surface of a fault. A ''fault trace'' or ''fault line'' is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geological maps to represent a fault. A ''fault zone'' is a cluster of parallel faults. However, the term is also used for the zone ...

Thrust Fault
A thrust fault is a break in the Earth's crust, across which older rocks are pushed above younger rocks. Thrust geometry and nomenclature Reverse faults A thrust fault is a type of reverse fault that has a dip of 45 degrees or less. If the angle of the fault plane is lower (often less than 15 degrees from the horizontal) and the displacement of the overlying block is large (often in the kilometer range) the fault is called an ''overthrust'' or ''overthrust fault''. Erosion can remove part of the overlying block, creating a ''fenster'' (or ''window'') – when the underlying block is exposed only in a relatively small area. When erosion removes most of the overlying block, leaving island-like remnants resting on the lower block, the remnants are called ''klippen'' (singular '' klippe''). Blind thrust faults If the fault plane terminates before it reaches the Earth's surface, it is called a ''blind thrust'' fault. Because of the lack of surface evidence, blind thrust fa ...

Rift
In geology, a rift is a linear zone where the lithosphere is being pulled apart and is an example of extensional tectonics. Typical rift features are a central linear downfaulted depression, called a graben, or more commonly a half-graben with normal faulting and rift-flank uplifts mainly on one side. Where rifts remain above sea level they form a rift valley, which may be filled by water forming a rift lake. The axis of the rift area may contain volcanic rocks, and active volcanism is a part of many, but not all, active rift systems. Major rifts occur along the central axis of most mid-ocean ridges, where new oceanic crust and lithosphere is created along a divergent boundary between two tectonic plates. ''Failed rifts'' are the result of continental rifting that failed to continue to the point of break-up. Typically the transition from rifting to spreading develops at a triple junction where three converging rifts meet over a hotspot. Two of these evolve to t ...

Jurassic
The Jurassic ( ) is a Geological period, geologic period and System (stratigraphy), stratigraphic system that spanned from the end of the Triassic Period million years ago (Mya) to the beginning of the Cretaceous Period, approximately 143.1 Mya. The Jurassic constitutes the second and middle period of the Mesozoic, Mesozoic Era as well as the eighth period of the Phanerozoic, Phanerozoic Eon and is named after the Jura Mountains, where limestone strata from the period were first identified. The start of the Jurassic was marked by the major Triassic–Jurassic extinction event, associated with the eruption of the Central Atlantic magmatic province, Central Atlantic Magmatic Province (CAMP). The beginning of the Toarcian Age started around 183 million years ago and is marked by the Toarcian Oceanic Anoxic Event, a global episode of Anoxic event, oceanic anoxia, ocean acidification, and elevated global temperatures associated with extinctions, likely caused by the eruption of the Kar ...

Gondwana
Gondwana ( ; ) was a large landmass, sometimes referred to as a supercontinent. The remnants of Gondwana make up around two-thirds of today's continental area, including South America, Africa, Antarctica, Australia (continent), Australia, Zealandia, Arabian Peninsula, Arabia, and the Indian subcontinent. Gondwana was formed by the Accretion (geology), accretion of several cratons (large stable blocks of the Earth's crust), beginning with the East African Orogeny, the collision of India and Geography of Madagascar, Madagascar with East Africa, and culminating in with the overlapping Brasiliano orogeny, Brasiliano and Kuunga orogeny, Kuunga orogenies, the collision of South America with Africa, and the addition of Australia and Antarctica, respectively. Eventually, Gondwana became the largest piece of continental crust of the Paleozoic Era, covering an area of some , about one-fifth of the Earth's surface. It fused with Laurasia during the Carboniferous to form Pan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Continental Collision
In geology, continental collision is a phenomenon of plate tectonics that occurs at Convergent boundary, convergent boundaries. Continental collision is a variation on the fundamental process of subduction, whereby the subduction zone is destroyed, mountains produced, and two continents sutured together. Continental collision is only known to occur on Earth. Continental collision is not an instantaneous event, but may take several tens of millions of years before the Geologic fault, faulting and Fold (geology), folding caused by collisions stops. Geology of the Himalaya, The collision between Indian plate, India and Eurasian plate, Asia has been going on for about 50 million years already and shows no signs of abating. Collision between East and West Gondwana to form the East African Orogeny, East African Orogen took about 100 million years from beginning (610 Ma) to end (510 Ma). The collision between Gondwana and Laurasia to form Pangea occurred in a relati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indian Plate
The Indian plate (or India plate) is or was a minor tectonic plate straddling the equator in the Eastern Hemisphere. Originally a part of the ancient continent of Gondwana, the Indian plate broke away from the other fragments of Gondwana and began moving north, carrying Insular India with it. It was once fused with the adjacent Australian plate to form a single Indo-Australian plate, but recent studies suggest that India and Australia may have been separate plates for at least 3 million years. The Indian plate includes most of modern South Asia (the Indian subcontinent) and a portion of the basin under the Indian Ocean, including parts of South China, western Indonesia, and extending up to but not including Ladakh, Kohistan, and Balochistan in Pakistan. Plate movements Until roughly , the Indian plate formed part of the supercontinent, Gondwana, together with modern Africa, Australia, Antarctica, and South America. Gondwana fragmented as these continents drifted apa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vadodara
Vadodara (), also known as Baroda, is a city situated on the banks of the Vishwamitri River in the Indian state of Gujarat. It serves as the administrative headquarters of the Vadodara district. The city is named for its abundance of banyan (''vad'') trees. Vadodara is also locally referred to as the ''Sanskrutik Nagari'' () and ''Kala Nagari'' () of India. The city is prominent for landmarks such as the Laxmi Vilas Palace, which served as the residence of the Maratha royal Gaekwad dynasty that ruled over Baroda State. It is also the home of the Maharaja Sayajirao University of Baroda. Etymology The city was once called Chandanavati after Raja Chandan of the Dod Parmar Rajputs. The capital was also known as Virakshetra (Land of Warriors). Later, it was known as Vadpatraka or Vadodará, and according to tradition, is a corrupt form of the Sanskrit word ''vatodara'', meaning "in the belly of the banyan tree". It is, as of 2009, almost impossible to ascertain when the vario ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gandhinagar
Gandhinagar () is the capital of the state of Gujarat in India. Gandhinagar is located approximately 23 km north of Ahmedabad, on the west central point of the industrial corridor between the megacities of Delhi and Mumbai. Gandhinagar lies on the west bank of the Sabarmati River, about 545 km (338 miles) north of Mumbai and 901 km (560 miles) southwest of Delhi. The Akshardham temple is located in Gandhinagar. There was a determination to make Gandhinagar a purely Indian enterprise, partly because the state of Gujarat was the birthplace of Mahatma Gandhi. For this reason, the planning was done by two Indian town planners: Prakash M Apte and H. K. Mewada, who had apprenticed with Le Corbusier in Chandigarh. Etymology The name of the city means "Gandhi's city" and it is named after Mahatma Gandhi. History The city was planned by Chief Architect H.K. Mewada, a Cornell University graduate, and his assistant Prakash M Apte. It was developed in the 1960s. Demo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
