Abstract
We describe a numerical method to measure the location and strength of complex singularities of a Hele-Shaw flow. We are able to detect the singularities with exponent (close to) -4/3, predicted by perturbative calculations. We also give numerical evidence for a new mechanism of singularity generation.
