No, earthquakes can occur anywhere in the crust, oceanic crust or continental crust. An earthquake occurs when the hard brittle solid material of the crust fractures under stress.
Earthquakes cannot occur deeper than the crust (the mantle is plastic and flows slowly under stress instead of fracturing, the outer core is liquid and flows even easier than the mantle).

This material is found only in the continental crust?
granite
What material is only found in continental crust?
Lava
Is oceanic crust is usually thicker than continental crust?
No. Oceanic crust is heavier and denser than continental crust, but is actually thinner. Continental crust is believed to actually extend down into the magma of the mantle (upon which crust floats) more deeply than oceanic crust, similar to how a huge ice cube will not only be larger above the surface of water than a smaller ice cube, but will extend more deeply into a glass than a small ice cube ... so not only does continental crust extend higher on the surface (since it is continental crust, it has dry land above the ocean floor), but the 'bottom' of the crust also extends deeper into the earth. Oceanic crust is thus thinner than continental crust, but made of denser, heavier rock (which is why it subducts under continental crusts where continental and oceanic plates converge).
What is the difference of continental crust and oceanic crust?
Two differences are that the oceanic crust is more dense than continental, and continental crust is composed mostly of granite, while oceanic is mostly basalt
Which layer of the Earth is the only layer that is known to contain life?
The only layer of the earth to contain life is the crust. The crust consists of two parts: the continental crust and the oceanic crust. The oceanic crust is below the oceans and is 4-7 miles thick. The continental crust is the surface you see. It is mostly water and 29% land.

Does the south American tectonic plate only have continental crust?
yes it does
What is a characteristic of subduction?
The correct answers are - B. Where oceanic crust meets continental crust, and C. Earthquakes.Subduction zones appear only on places where a crust of lower density (oceanic crust) meets a crust of higher density (continental crust).On the places where the oceanic crust meets the continental crust, the oceanic crust goes beneath the continental crust, this makes changes and readjustments in the inner part of the crust, and plus there's significant pressure from the mantle layer from beneath, so earthquakes are a very common occurrence.Check all that apply. A. Broad river deltas B. Where oceanic crust meets continental crust C. Earthquakes D. Two continents collide
How many tectonic plates are composed of only continental crust?
none they all contain some oceanic crust
Why do composite volcanoes occur at the boundary between oceanic crust and continental crust?
The simple answer: Oceanic crust is more dense than the continental crust, so it goes under as the two plates ram into each other. (This is called subduction) This submerged crust melts into magma, and collects into a large pool under the continental plate where it went under. The pool of magma forces its way up to form a volcano, which sits in front of us and blows when least expected. The whole process takes a very long time. Also, it only happens in convergent boundaries.
Do lithospheric plates include both continental crust and oceanic crust?
It is possible to have continental and oceanic crust on the same plate. The only to this exception is with the Pacific plate which exists independently.
What events can cause earthquake?
Earthquakes are caused when two continental plates slide together. The crust of the earth is not one piece, but many that move extremely slowly. Only sliding plates can cause earthquakes. Hope this helped!
Are oceanic plates only made up of oceanic crust?
yes but oceanic crust is younger than continental crust because of deep sea trenches
