Where Can an Aseismic Ridge Be Found? An Aseismic Ridge can be found under the ocean. It may start at a point where there is volcanic activity on an island or seamount on the ocean floor.
How did the Ninetyeast ridge form?
The Ninetyeast Ridge is an ∼5500 km long, north–south-oriented, submarine volcanic ridge in the eastern Indian Ocean that formed from magmatism associated with the deep-seated Kerguelen mantle plume as the Indian plate drifted rapidly northward during the Late Cretaceous.
When was the Ninety East Ridge formed?
million years ago 90 East Ridge Formation (94 Ma – present) Video including 90 East Ridge Formation (94 Ma (million years ago) – present).
What is the meaning of aseismic?
This term describes a fault on which no earthquakes have been observed.
Are mid-ocean ridges?
Mid-ocean ridges occur along divergent plate boundaries, where new ocean floor is created as the Earth’s tectonic plates spread apart. … Two well-studied mid-ocean ridges within the global system are the Mid-Atlantic Ridge and the East Pacific Rise.
Where is the Ninety East Ridge?
The Ninety-East Ridge (NER) is 5000 km long linear bathymetric feature striking more or less paralle to the 90°E meridian from south of Broken Ridge (at ~31°S), southwest of Australia, north to the Bay of Bengal, east of India.
Why Ninety East Ridge name has been given to this ridge?
This landform is named as the ‘Ninety East Ridge’ because it is located near the spot where parallel strike along the 90th meridian at the centre of the Eastern Hemisphere. This is one of the important relief features of the Indian Ocean because it divides the Indian ocean into West and East Indian Ocean.
Where is the Carlsberg Ridge?
Carlsberg Ridge, submarine ridge of the Arabian Sea and the Indian Ocean. The ridge is a portion of the Mid-Indian Ridge and extends from near Rodrigues Island to the Gulf of Aden, trending basically northwest to southeast. The ridge separates the Arabian Sea to the northeast from the Somali Basin to the southwest.
Why is the Indian Ocean?
The Indian Ocean has been known by its present name since at least 1515 when the Latin form Oceanus Orientalis Indicus (Indian Eastern Ocean) is attested, named for India, which projects into it.
How long is the Southeast Indian Ridge?
6,000 km A divergent tectonic plate boundary stretching almost 6,000 km (3,700 mi) between the Rodrigues Triple Junction (25°S 70°E) in the Indian Ocean and the Macquarie Triple Junction ( 63°S 165°E) in the Pacific Ocean, the SEIR forms the plate boundary between the Australian and Antarctic plates since the Oligocene (anomaly …
Where is the Kerguelen Plateau?
Southern Ocean Kerguelen Plateau is one of the largest volcanic plateaus in the world and the largest in the Southern Ocean. It lies about 3 000km to the southwest of Fremantle (Western Australia) and is nearly three times the size of Japan or four times the size of the British Isles.
What is an aseismic zone?
/ (eɪˈsaɪzmɪk) / adjective. denoting a region free of earthquakes. (not in technical use) denoting a region free of all but a few small earthquakes. (of buildings, etc) designed to withstand earthquakes.
What is aseismic fault slip?
In geology, aseismic creep or fault creep is measurable surface displacement along a fault in the absence of notable earthquakes. … Notable examples of aseismic slip include faults in California (e.g. Calaveras Fault, Hayward Fault, and San Andreas Fault).
What is a seismic safe structure?
Earthquake-resistant or aseismic structures are designed to protect buildings to some or greater extent from earthquakes. … According to building codes, earthquake-resistant structures are intended to withstand the largest earthquake of a certain probability that is likely to occur at their location.
How do ridges form?
A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.
What are some examples of mid ocean ridges?
Mid-ocean ridges are typically half a mile to six miles wide and over a mile underwater. Two of the most well-known mid-ocean ridges are the Mid-Atlantic Ridge and the East Pacific Rise. As you might guess, most of the Mid-Atlantic Ridge is in the Atlantic, and most of the East Pacific Rise is in the Pacific.
What is the largest underwater mountain range?
The mid-ocean ridge The mid-ocean ridge is the longest mountain range on Earth. The longest mountain range on Earth is called the mid-ocean ridge. Spanning 40,389 miles around the globe, it’s truly a global landmark. About 90 percent of the mid-ocean ridge system is under the ocean.
Is there a Mid Pacific ridge?
The East Pacific Rise is a mid-oceanic ridge, a divergent tectonic plate boundary located along the floor of the Pacific Ocean. It separates the Pacific Plate to the west from (north to south) the North American Plate, the Rivera Plate, the Cocos Plate, the Nazca Plate, and the Antarctic Plate.
What plate boundary is the Carlsberg Ridge?
The Carlsberg Ridge is the northern section of the Central Indian Ridge, a divergent tectonic plate boundary between the African Plate and the Indo-Australian Plate, traversing the western regions of the Indian Ocean.
Which is the largest island in the Indian Ocean?
Madagascar The Largest Islands in the Indian Ocean

Why is ocean named after India?
The location of India is very strategic as it can oversee the trade routes connecting the West to the East. … The Indian Ocean is named after India because of its strategic location at the head of the ocean from ancient times and its long coastline which is longer than any other country in the Indian Ocean rim.
Which is the deadliest ocean?
The South China Sea and East Indies, eastern Mediterranean, Black Sea, North Sea, and British Isles are the most dangerous seas in the world, with the greatest number of shipping accidents in the last 15 years, according to a report released by the World Wildlife Fund (WWF).
Is Indian Ocean owned by India?
However, the Indian Navy claims the entire Indian Ocean as its area of responsibility and prides itself on being the first to respond to natural and humanitarian disasters there. While France and India are the key regional players on security, the UK also plays an important role.
Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
