The frequency that that thing vibrates is called "Natural frequency". Moreover, each building has its own natural frequency.

The more earthquake happens, the more destruction to the building. Moving direction of vibration Every kind of waves (any direction) can affect the destruction level of an earthquake. This includes Body wave( S-wave and P wave) and Surface wave ( Love wave and Rayleigh wave) Latitude of the location Seismic energy is distributed differently in the different latitude of the location. The energy released in Southern hemisphere is 30 per cent lower than the energy released in

Our group wants to illustrate that not all the earthquakes are scary. You will see 6 earthquake scenes in the movies and 6 screen captures of real earthquake video clips that have a similar magnitude in order to compare the damage of the building, road etc. However, our group understands that to entertain the audience, computer graphics and a variety of tools are essential to the movies. Our group has no intention to criticize the movie and movie producers. 1. Ashfall Ashfall is a Korean movie and was released in 2019. The movie demonstrated a 7.8 magnit ude earthquake, which caused a major effect.  The chosen video clip demonstrates the same earthquake magnitude in Kaikoura, New Zealand, which happened in 2016. Movie scene 1 : The road collapses and creates a large ho
