The ARGONET (Greece) Seismic Observatory: An Accelerometric Vertical Array
The ARGOstoli NETwork (ARGONET) consists of a vertical seismic array and a nearby free-field station located in Cephalonia, western Greece, in the vicinity of the Cephalonia Transform Fault Zone (CTFZ) which is characterized by some of the highest seismic activity levels in Europe.
In this session, special guest speakers Dr. Nikolaos Theodoulidis & Dr. Fabrice Hollender will walk us through this amazing project, describing the infrastructure and the scientific results it has enabled. The speakers will also present tests carried out to demonstrate the efficiency of the innovative ‘glass bead’ coupling solution, as well as a procedure followed to estimate the sensors’ orientation by using signals from distant large magnitude earthquakes.
ARGONET is intended to investigate the effects of local surface geology on the incoming seismic wavefield, with emphasis on strong ground motion. The vertical array is composed of accelerometer sensors placed on the ground surface at 5.6, 15.5, 40.1, and 83.4m depths.
ARGONET started operation in July 2015, and as of 30 April 2017, had generated high-quality recordings of nearly 1,000 local and regional earthquakes. The event dataset and metadata are openly available.
ARGONET data have already enabled several scientific studies, including the spectacular demonstration of variations in shear wave propagation velocity and site response as a function of rainfall; as well as the qualification of a method based on the use of seismic coda for the estimation of the site effects and of the earthquake source time function.
This informative webinar + Q&A is a must-see for researchers, operators, and engineers.
We look forward to seeing you there!
