Earthquakes and Volcanoes



In what ways are earthquakes like volcanoes ?


46 comments:

  1. 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.

    Most earthquakes directly beneath a volcano are caused by the movement of magma. The magma exerts pressure on the rocks until it cracks the rock. Then the magma squirts into the crack and starts building pressure again. Every time the rock cracks it makes a small earthquake. These earthquakes are usually too weak to be felt but can be detected and recorded by sensitive instruments. Once the plumbing system of the volcano is open and magma is flowing through it, constant earthquake waves, called harmonic tremor, are recorded (but not felt).

  4. Volcanoes and earthquakes are seemingly very different geological events, yet they are actually closely related - both result from movements of Earth's crust.

  5. they both involve shaking the earth

  7. Earthquakes are like volcanos because they're both destructive. (Most of the time)

  9. Volcanos and earthquakes are alike because they occur in the same area and they are both are natural distaters

  22. They both shake the ground and make loud noises when they happen.

  23. they both do damage so they are like the same

  24. Some earthquakes occur along the earth's tectonic plates, then, sometimes, volcanoes are made along tectonic plates.

  25. They both have to do with rocks and make loud noises.

  34. Volcanoes and earthquakes are seemingly very different geological events, yet they are actually closely related - both result from movements of Earth's crust. Earth's crust - the lithosphere - is composed of several major plates and many minor plates that change shape and position. Over time, these tectonic plates move, interact with each other, and are responsible for the formation of ocean basins, mountain ranges, islands, volcanoes, and earthquakes.

  35. they both happen when earths plates move

  36. They both shake the earth around it breaking things in there way.

  39. Earthquakes and volcanos are similar because they are both started under ground. Magma builds up under the ground and plates shift under the ground.

  42. Volcanoes shake and spew out lava. Earthquakes shake and bring down buildings. Both volcanoes and earthquakes change the atmosphere around them in sometimes fatal ways.
