An item may sometimes be described as being a virtual item when it is a representation or non-tangible abstraction of the physical object, or is a functional emulation or simulation of it.
With high-performance computing (HPC), it is possible to utilise physics-based models to gain insights into ground motions recorded during earthquakes and built infrastructure responses. An EU-funded project has now provided the algorithms and software necessary for the 3D inversion of geophysical data.
