    Crete Island (Greece), located in the front of the Hellenic subduction zone, is in continuous need of seismic monitoring. Aiming increasing seismic readiness and provide more knowledge-information to citizens and civil protection authorities, the Hellenic Seismological Network of Crete (HSNC) started operating a permanent strong ground motion (SGM) network in the urban environment of Chania and its southern basin. The network is equipped with sensors as that of Trimble’s Reftek 130 along with the Satways’ GSense 16bit ones aiming to build a dense network with increased spatial resolution in the monitoring area. The SGM sensors monitoring capabilities, the network topology and the geological characteristics in the installation sites are presented. In the test period 2015-2017, one of our intentions was to investigate the seismic amplification in Chania basin which covers the contemporary part of the city, the Venetian old town and the fast-developing southern basin. Spectral ratio techniques have been used on ambient noise (H/V) and seismic signal (RF) to provide supplementary information for the local site conditions in station locations. Analysis of the strong motion data enables us to calculate the peak ground acceleration and present it in a GIS environment. Different interpolation techniques have been tested. The results support the importance of use of low cost Urban SGM sensors to enhance civil protection activities.
