Earthquake simulation applies a real or simulated vibrational input to a structure that possesses the essential features of a real seismic event. Earthquake simulations are generally performed to study the effects of earthquakes on man-made engineered structures, or on natural features which may present a hazard during an earthquake.
QuakeSim is a NASA project for modeling earthquake fault systems.It was started in 2001 with NASA funding as a follow-up to the General Earthquake Models (GEM) initiative. The multi-scale nature of earthquakes requires integrating data types and models to fully simulate and understand the earthquake process.
Awesome Earth looks at natural disasters and geology, featuring a Tesla coil and an earthquake simulator. The Q Lab has a dynamic experiment space and includes the Questacon Beehive exhibit. The Shed contains experimentation with ideas, tools, science, technologies, and art. MiniQ is designed for children between the ages of 0 and 6.
The centrifuge capacity in terms of the maximum acceleration multiplied by the maximum payload is 53 g x 4500 kg = 240 g-tonnes. The NEES centrifuge at the Center for Earthquake Engineering Simulation (CEES) at Rensselaer Polytechnic Institute has a nominal radius, 2.7 m, which is the distance between the center of payload and the centrifuge axis.
Earthquake shaking tables are essential in model testing contests, where participants evaluate designs developed within specific guidelines against simulated seismic activity. [5] Simple shake tables are also used in architecture and structural engineering primarily for educational purposes, helping students learn how structures respond to ...

Seismic analysis is a subset of structural analysis and is the calculation of the response of a building (or nonbuilding) structure to earthquakes. It is part of the process of structural design, earthquake engineering or structural assessment and retrofit (see structural engineering) in regions where earthquakes are prevalent.
Earthquake loss estimation is usually defined as a Damage Ratio (DR) which is a ratio of the earthquake damage repair cost to the total value of a building. [62] Probable Maximum Loss ( PML ) is a common term used for earthquake loss estimation, but it lacks a precise definition.
