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).

What material is only found in continental crust?
Granitic rock is a material that is primarily found in continental crust. It is composed of minerals like quartz, feldspar, and mica, and is associated with the lighter composition characteristic of continental crust compared to oceanic crust.
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
This material is found only in the continental crust?
The material you are referring to is likely granite. Granite is a common rock type found in the continental crust, consisting mainly of quartz, feldspar, and mica minerals. It is typically associated with continental landmasses and is less common in oceanic crust.
How Continental crust is about times thicker than oceanic crust.?
Continental crust is typically about 30-50 km thick, whereas oceanic crust is only about 5-10 km thick. This difference in thickness is primarily due to variations in composition and density between the two types of crust. Continental crust is made up of less dense, older rocks, while oceanic crust is composed of denser, younger basaltic rocks.
What material is only found in continental crust?
Granitic rock is a material that is primarily found in continental crust. It is composed of minerals like quartz, feldspar, and mica, and is associated with the lighter composition characteristic of continental crust compared to oceanic crust.
How many tectonic plates are composed of only continental crust?
Some geologists believe there are no tectonic plates composed solely of continental crust, as plates typically consist of both continental and oceanic crust. The concept of a plate composed entirely of continental crust is not widely accepted in the field of plate tectonics.
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.
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.

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
How many times thicker is the continental crust to the oceanic crust?
The continental crust is about 35 to 40 kilometers thick, while the oceanic crust averages at about 7-10 kilometers thick. This means that the continental crust is about 3.5 to 4 times the thickness of the oceanic crust.
Is the continental crust more than 5 times as thick as ocenic crust?
Oceanic crust is 6 to 11 kilometers thick while the continental crust is 100 kilometers thick, so the continental crust is more than five times as thick as the oceanic crust. I hope this well will help for the future and current time.
This material is found only in the continental crust?
The material you are referring to is likely granite. Granite is a common rock type found in the continental crust, consisting mainly of quartz, feldspar, and mica minerals. It is typically associated with continental landmasses and is less common in oceanic crust.
Are oceanic plates only made up of oceanic crust?
yes but oceanic crust is younger than continental crust because of deep sea trenches
Is granite everywhere?
No. It only occurs in areas of continental crust and is only present at the surface in a small percentage of that.
How Continental crust is about times thicker than oceanic crust.?
Continental crust is typically about 30-50 km thick, whereas oceanic crust is only about 5-10 km thick. This difference in thickness is primarily due to variations in composition and density between the two types of crust. Continental crust is made up of less dense, older rocks, while oceanic crust is composed of denser, younger basaltic rocks.
What are two kinds of crust involved in a subduction zone?
Both continental and oceanic crusts are used in the process of subduction, unless you are talking about see floor spreading, then only oceanic crust is used
