How The Initial Collision Occurred?

But there are some anomalies as there are earthquakes which don’t take place on a plate boundary and it’s the same with volcanoes. An example of this is Hawaii. Hawaii is a volcanic island which is found in the middle of a tectonic plate. Hawaii is an example of a hotspot. The places known as hotspots are volcanic regions thought to be fed by underlying mantle that is anomalously hot compared with the mantle elsewhere. They may be on, near to, or far from tectonic plate boundaries. There are two hypotheses to explain them. One suggests that they are due to hot mantle plumes that rise from the core-mantle boundary. The other hypothesis postulates that it is not high

The 1906 San Francisco Earthquake tectonic setting was in the outermost shell of earth known as the crust this is composed of rigid plates that have been moving for hundreds of millions of years. Two of these moving plates meet in western California; the boundary between them is a zone of faults, the principal one being the San Andreas fault. The horizontal sliding of the Pacific Plate relative to the North American Plate, causes earthquakes along the San Andreas fault and similar plates near the region. The San Andreas fault is a transform plate boundary, accommodating horizontal relative motions (usgs.gov).

The tectonic setting for the 1906 San Francisco Earthquake was in the outermost shell of earth consisting of rigid plates that have been moving for hundreds of millions of years. Two of these moving plates meet in western California; the boundary between them is a zone of faults, the principal one being the San Andreas fault. The Pacific Plate (on the west) slides horizontally northwestward relative to the North American Plate (on the east), causing earthquakes along the San Andreas and associated faults. The San Andreas fault is a transform plate boundary, accommodating horizontal relative motions (usgs.gov).

Plate tectonics are very dangerous when they collide,slide,and move apart. They can create mountains like the Appalachian Mountains that used to tower over everything then erosion took place. The Appalachian Mountains were formed by convergent boundaries, convergent boundaries are collide

Earth's plates and continents do not always just stay in one place. They shift, collide, and move apart, causing destruction in many different parts of the world. The movement of plates causes volcanic eruptions, changes in the oceans, and perhaps the most dangerous of all, earthquakes. Earthquakes may have the most devastating effects on people and cities.

Earthquakes are caused when two blocks of earth suddenly slip past one another. The surface where the two blocks slip is called the fault. The earthquake starts below the earth’s surface at the hypocenter, and the location above the hypocenter is called the epicenter. Earthquakes can have foreshocks which is a smaller earthquake that happens before the larger quake. Earthquake can also

Megathrust earthquakes are defined as interplate earthquakes caused by one tectonic plate being forced under another in a subduction zone. During the lifetime of a subduction zone, two plates are constantly moving towards each other, and due to the great amount of friction, these plates get “stuck” in various areas 2 (fig 1). Due to the build-up of stress in these areas, the plates eventually unlock and release a great amount of energy, resulting in a megathrust earthquake2.

By definition an earthquake is the tremor of the surface of the Earth, sometimes severe and devastating, which results from shock waves generated by the movement of rock masses deep within the Earth, particularly near boundaries of tectonic plates. The tectonic plates involved in the 2010 Chile earthquake were the Nazca and South American plate, and like all tectonic plates, they often move due to convection currents within the Earth’s mantle. This movement can cause tectonic plates to collide, separate or slide past one another. For thousands of years, the oceanic Nazca plate has been colliding and slowly subducting underneath the continental side of the South American plate. Earthquakes can be caused by a variety of reasons, but the 2010 Chilean earthquake was caused by these two tectonic plates having an ocean-continental collision at a convergent boundary.

The most common cause of earthquakes is movement along faults. Earth’s crust is divided into tectonic plates, which grind past each other at fault boundaries. As tectonic plates move,

The seven major tectonic plates comprise mostly on continental plates and the Pacific plate. The seven major plates from greatest to least are called: the Pacific Plate stretching 103,300,000 km2, North American Plate being 75,900,000 km2, Eurasian Plate being 67,800,000 km2, African Plate stretching 61,300,000 km2, Antarctic Plate being 60,900,000 km2, Australian Plate being 47,000,000 km2, and the South American Plate being 43,600,000 km2. With different tectonic plates, there are different ways they can move: divergent, convergent, and transform. Divergent plate movement is when both plates moving away from each other, creating a canyon that has magma pushing out from the bottom, forming new ground. Convergent is usually an oceanic plate and a continental plate are moving into one another, causing the oceanic plate to subducts into the mantle. This causes move active volcanos and earthquakes. Even though all of the plates are in the lithosphere, it's only the where Earth is flexible enough to move rather than flow. The lithosphere flexes when loads of weight are placed on it or

This can cause minor earthquakes to occur (however not as powerful as earthquakes caused by Subduction).

The 9.0 magnitude Indian Ocean earthquake was caused by subduction under the Indian Ocean. Earthquakes are usually caused by convection currents leading to subduction/convergent currents. Convection currents is caused by magma rising from the deepest part of the earth, then slowly cooling, sinking again then re-heating, then rising upwards basically repeating the rising and cooling then re-heating cycle over and over again. The plates are separated from each other and they move apart, the plates then obviously hit another plate right next to it causing subduction. This earthquake was caused on the Oceanic crust, in the Indian Ocean, creating tsunamis that caused disasters and thousands of life loss throughout the Indian Ocean basin. The

At the beginning of the period, the European plate collided with India. This caused the Himalayan mountains to form. During this time, the sea levels were low and Antarctica was covered

2. From the map, we understand that it’s where the surface of the world is really a series of “plates” floating on the magma (lava) layers below the surface. Scientists call the plates, tectonic plates. India is on a separate plate too much of Asia, as is much of what several call the Middle East. Throughout many millions of years what was thought to be one large mass of land has broken up with sections drifting away. Many refer to it as ancient landmass Pangaea. After studying, I learned that Pangaea started breaking up about 200 million years ago. At that time, what was to become India was closer to Africa, Antarctica and Australia. India’s plate broke away and headed north eventually running into the Eurasian plate where

The Everest and Himalayas are energetic topographically talking. They began to edge more than 65 million years former when two sweeping crustal plates' Eurasian plate land and Indo-Australian plate affected. The particular Indian subcontinent steamed towards upper eastern, smashing into Asian countries, slipping in addition to forcing the reason why connected with reductions in the discs, in addition to dependably forcing the Himalayas over a few mile after mile large.
