Welcome to JHVIT’s documentation!
JHVIT is a python package for locating seismic event hypocenters on unstructured grids. The package is an extension of the joint hypocenter-velocity inversion method on tetrahedral meshes. It is mainly recommended for domains with steep topography, underground cavities and stratigraphic and abnormal geological contacts such as folds, faults and shear zones. The code is able to locate a wide range of seismic events going from major earthquakes and nuclear explosions to low and negative magnitude events. Target application areas include computational seismology, hydraulic fracture and microseismic monitoring of mining environments or in civil engineering projects.
The package is written in Python, uses an optimized c++ raytracing code wrapped in Cython and supports parallel computing.
