  We analyze the data from the 6 gravitational waves signals detected by LIGO
through the lens of multifractal formalism using the MFDMA method, as well as
shuffled and surrogate procedures. We identified two regimes of multifractality
in the strain measure of the time series by examining long memory and the
presence of nonlinearities. The moment used to divide the series into two parts
separates these two regimes and can be interpreted as the moment of collision
between the black holes. An empirical relationship between the variation in
left side diversity and the chirp mass of each event was also determined.
