Abstract
ISOLA software package has been developed to invert local or regional full- wave seismograms for single - and multiple -point source models. The c ode was introduced in 2003 ; since th en it has been continually upgraded, and , presently, it can be considered a well- established tool, used worldwide.
Originally, the code name came from 'isolated asperities', to be resolved at fault planes of large earthquakes. However, with time, the code has been ad apted for very diverse applications, ranging from Mw 0.3 to 9.
Many research papers based on us age of ISOLA have been published (see References). Almost every new application is challenging - hence the code is continually updated.
The objective of this work is to explain the basic principles of the method, review code status, demonstrate a few examples to attract new users , and shortly touch also future development. The code is free, and can be downloaded together with manual and test examples from http://seismo.geology.upatras.gr/isola/ (last accessed June 2017).
