From: Solution of underdetermined systems of equations with gridded a priori constraints
Two cases of modelling of seismic faults with TOPINV algorithm. The inversion was basedon limited GPS observations using a priori information (constraints to the fault characteristics derived from geological/seismological information). Top (a), (b): two different cases of oblique strike slip faults. Reference and modelled faults and displacement vectors are shown. Solid lines indicate their surface trace and rectangulars their projection on the surface. Observation stations are marked with numbers. Shaded rectangles indicate the likely position of the centre of the fault. Bottom (c), (d): Deviations of estimated values from their reference values (zero lines) and their 1-σ standard deviations for each case respectively. Units for each variable are marked on the each variable, also is shown the a priori assumed possible range of values, used to form the initial grid.
