The objective of this paper is to define seismic zones in the Azores based
on statistical criteria. These seismic zones will likely be used in seismic
simulations of occurrences in the Azores Archipelago.
The data used in this work cover the time period from 1915 to 2011. The
Azores region was divided into 1° × 1° area units, for which the seismicity and the maximum magnitudes of
events were calculated.
The seismicity, the largest earthquakes recorded and the geological
characteristics of the region were used to group these area units because similar
seismic zones must delineate areas with homogeneous seismic characteristics.
We have identified seven seismic zones.
To verify that the defined areas differ statistically, we considered the
following dissimilarity measures (variables): time, size and seismic conditions – the number
of seismic events with specific characteristics.
Statistical tests, particularly goodness-of-fit tests, allowed us to
conclude that, considering these three variables, the seven earthquake zones
defined here are statistically distinct. |
