A tragic hero can be defined simply as the protagonist of a tragedy. The Greek philosopher Aristotle, however, endowed this individual with a number of specific characteristics. The first of which is his ability to evoke fear and pity from an audience.
Earthquakes are caused by either volcanic activity or shifting of massive tectonic plates underneath the surface of the earth. The plates have a ton of pressure and are pressing against each other, and when the plates suddenly shift it causes the entire ground to move, shake or break apart.
Three things that happen to the Earth's crust when earthquakes  occur include, a release in energy, plates sliding past one  another, and fractures developing in the crust. â¦ Not all of these  things happen at the same time and which occurs depends on the  strength of the earthquake. 1 person found this useful.
