What is it about?
The sharp increase of seismic activity in the southern shores of Saronikos Gulf (Greece) led to the investigation of the distribution of local body wave (P-S) velocities and Vp/Vs ratio, producing a new 3-D model.

Why is it important?
It's important due to the nature of the area which is partially volcanic and the identification of certain velocity patterns may help to constrain the risk of the region and where there should be enhancement of the seismological network in order to have a closer look into the plumbing system of the NW edge of Hellenic (Greek) Volcanic Arc.
Perspectives
The 2016-2017 Poros (Saronikos, Greece) earthquake swarm gave us the opportunity to upgrade the local seismological network and the local seismological catalogues. That was a good change to investigate the local body-wave velocity pattern, how this could be linked to active magmatic chambers of the region, distinguish partial melts and plutonites (deep magmatic bodies that weren't ejected to the surface through an eruptive event) and whether the local fault pattern could facilitate the process of migrating fluids producing a swarm as the one that is described in the study.
