SUMMARYHigh seismicity makes it very likely forthe ARGONET to capture strongground motion in the near future.Open data & metadata offeropportunities for site response study.
Promising indication for increasedlikelihood of clearly observing non-linear site response especially in thetopmost layers, soon.
The detailed knowledge of thedynamic and geometrical propertiesof the site would then allow to testand upgrade 1D/2D/3D wavepropagation methods and codes.
The ARGONET high dynamic rangeand sensitivity array operates in realtime continuous streaming mode,aiming to serve as a near-faultobservatory providing information onthe study site ‘before-during-after’the occurrence of a strongearthquake.
