explain where earthquakes are most likely to originate?

explain were earthquakes are more likely to originate and why they originate in these places. most major earthquakes originate from the strain that builds up along faults. ... the epicenter of an earthquake is the point on earth's surface directly above the focus of an earthquake.

Thus, earthquakes that occur along coastlines or anywhere beneath the oceans can generate tsunamis. The size of the tsunami is usually related to the size of the earthquake, with larger tsunamis generated by larger earthquakes. But the sense of displacement is also important.

3/4 of all earthquakes occur at convergent boundaries. Many mountain ranges occur along these lines because when one plate doesn't completely move under the other, the earth crumbles and this uplifts the crust into mountains. In Europe, the Alps are formed from the African and Eurasian plate bumping into each other.

Earthquakes occur all the time all over the world, both along plate edges and along faults. Most earthquakes occur along the edge of the oceanic and continental plates. The earth's crust (the outer layer of the planet) is made up of several pieces, called plates.

Some, but not all, earthquakes are related to volcanoes. For example, most earthquakes are along the edges of tectonic plates. This is where most volcanoes are too. However, most earthquakes are caused by the interaction of the plates not the movement of magma .

Are earthquakes scattered randomly over the surface of the earth or are they concentrated in definite zones? Earthquakes are scattered around the globe. However, they are fixed around certain areas on the edges of faults. ... Volcanoes, like earthquakes, can be found all over the earth.

About 80% of earthquakes occur where plates are pushed together, called convergent boundaries. Another form of convergent boundary is a collision where two continental plates meet head-on.

Subduction Zones are Potential Tsunami Locations Most tsunamis are caused by earthquakes generated in a subduction zone, an area where an oceanic plate is being forced down into the mantle by plate tectonic forces. The friction between the subducting plate and the overriding plate is enormous.

Volcanoes form at Earth's surface whereas earthquakes originate from deeper within the crust. ... Volcanoes are formed by release of gas and magma. Earthquakes are caused by movement along a fault. Volcanoes lead to the formation of new rock whereas earthquakes simply cause waves which disturb the rock.

Earthquakes and Seismic Waves. When an earthquake occurs, rocks at a fault line slip or break, and two sections of Earth's crust physically move relative to one another. That movement releases energy, and two types of seismic waves radiate outward from the earthquake through Earth's interior and along its surface.

There are many different types of earthquakes: tectonic, volcanic, and explosion. The type of earthquake depends on the region where it occurs and the geological make-up of that region. The most common are tectonic earthquakes.

Causes of Earthquake Earthquakes are caused by sudden tectonic movements in the Earth's crust. The main cause is that when tectonic plates, one rides over the other, causing orogeny collide (mountain building), earthquakes. The largest fault surfaces on Earth are formed due to boundaries between moving plates.

Japan has the most recorded earthquakes, with Indonesia believed to be the country to have more seismic activity (due to its size). The nation sits where four major plates meet, with the converging point being right off the eastern coast of Kanto and Chubu (where Tokyo, Yokohama, Shizuoka, and Nagoya are).
808834
Earthquakes that generate tsunamis most often happen where Earth's tectonic plates converge, and the heavier plate dips beneath the lighter one. Part of the seafloor snaps upward as the tension is released. ... The falling debris displaces the water from its equilibrium position and produces a tsunami.

Where does most of Earth's earthquakes, volcanoes, and mountain building occur? At plate boundaries.

Most earthquakes occur along the edge of the oceanic and continental plates. The earth's crust (the outer layer of the planet) is made up of several pieces, called plates. The plates under the oceans are called oceanic plates and the rest are continental plates.

The Pacific Plate (on the west) moves northwestward relative to the North American Plate (on the east), causing earthquakes along the fault. The San Andreas is the "master" fault of an intricate fault network that cuts through rocks of the California coastal region.
