We exploit a new template matching based catalogue to study the spatial
and temporal patterns of seismicity in the Eastern and Southern Alps. Data
from the AlpArray Swath-D network from late 2017 to late 2019 were used to
enhance the resolution of the seismic catalogues provided by local
agencies. The template matching method was implemented using our own
GPU-accelerated algorithm to deal with the large data volume. All events
are relocated using waveform-based picking methods.
Based on this result, we study statistical characteristics of the extended
seismicity catalogue, which now has a magnitude of completeness of Mc=0.6
and contains about 7,500 seismic events. We analyse the main spatial and
temporal features of seismicity revealed by this novel dataset. Finally,
we analyse specific event clusters that originated from the template
matching method, and seek to link event interconnectivity to geometrical
properties of the clusters.
