This animation shows the different effects produced by an earthquake on the conventional and anti seismic foundation of a building [source, Said Lopez: buff.ly/3nPrt7j]
Anti-seismic fondation can use several kinds of dampeners. This is a bi-directional dynamic loading test on steel damper for base isolated buildings simulating the behavior caused by earthquake [source, full video, Tokyo Tech: buff.ly/3mV1cDo]
Another kind of anti-seismic foundation is obtained using pendulum bearings that consist of an upper/lower spherical plate with sliding surface applied with special coating and a moving disc [source, full video, magebagroup: buff.ly/2L1BOhO]

The actual computational requirements for running an uploaded human mind are very difficult to quantify & strongly depend on the chosen level of simulation model scale. In other words, if you want a very precise copy, you need a ginormous processing power buff.ly/2G0UCYG
There is, however, a different approach to mind uploading that uses a completely different set of technologies: mind virtualisation, i.e. extracting a number of characteristics from a mind to develop a model that can be used to simulate future behaviour buff.ly/2KdpXg4

People have speculated over the nature of seemingly useless physical human characteristics for thousands of years. It wasn’t until the late 18th and early 19th centuries, though, that the idea of vestigiality would enter the public imagination ow.ly/jS5l30oigUH
Examples of human vestigiality are numerous, including the anatomical, the behavioral, and molecular. Among behavioral, goosebumps are caused by your arrector pili, the smooth muscle fibers that contract involuntarily when you are stressed, excited or cold buff.ly/2FRw2u7
The palmar and plantar grasp reflex is found in infants of humans and most primates. When an object is placed in an infant's hand or close to a foot, the fingers or the toes will close reflexively, as the object is grasped via palmar grasp ow.ly/Vj3830oiid1
