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.
The Triaxial Earthquake and Shock Simulator (TESS) is [1] an experimental 3-dimensional "shake table," is used to test the ability of systems and facilities to survive under realistic conditions of weapons-induced shock and vibration, and earthquake ground motion. TESS serves in a wide variety of testing roles, including testing shock ...
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.
The National Research Institute for Earth Science and Disaster Resilience (Japanese: 防災科学技術研究所, romanized: Bōsai Kagaku Gijutsu Kenkyū-sho), also known as NIED, is a National Research and Development Agency [1] that conducts research on science and technology related to disaster risk reduction. [2]

The Tri-Axial Seismic Simulator, or Shaking Table, can produce earthquake ground motions in six degrees of freedom, with motion in 3 axes. The shaking table is 5m x 5m and has a mass of 27 tons. It can take models of large scale buildings weighing up to 50 tons, and the square shape of the table provides large bending and torsional stiffness.
It is routinely used to provide post-earthquake situational awareness for emergency management and response and for damage and loss estimation. ShakeMap is also the primary shaking hazard input for many other downstream USGS earthquake products, including ShakeCast's assessments of critical facilities, PAGER 's societal losses, and estimates of ...
