Abstract
The Multifractal Detrended Fluctuation (MF-DF)
algorithm is applied to measure the complexity of two time series,
the inter-event hypocentral distance Δδ(t), and the inter-event time
series Δτ(t) In particular, we apply this methodology to the seismic
sequences produced in the Carterbury region during 18 years
(2000-2018). Results indicate a clear multifractal behavior of
Δδ(t) and Δτ(t). Moreover, an increses in the complexity is
observed when a large event occurs . These results suggest that the
MF-DF algorithm could be useful as a seismic precursor index.
