Well, quite often yes. At least in the areas I know (computational physics, quantum chemistry, weather and climate modelling, engineering, things like that).

Two other usage patterns I can think of are large strings processing (think bioinformatics and genetics), and things with neural networks (which to be fair would be a natural fit for Fortran, if the libraries were not mainly developed in C++ and accessed from Python). Still, on the HPC facilities I use, number crunching in large arrays dominates used CPU time, and I would say about half of them are in Fortran.
