Objectives&Activities (updated - following the reallocation of funds from 2016 to 2017)

The main objective of the project is to improve the knowledge of the nature and origin of the ambient seismic noise recorded on the Romanian territory.

 REASoN has several specific objectives with the following associated activities:

O1.1 Characterization of ambient seismic noise at seismic arrays.

Activity 1.1.1 Estimation of diurnal and seasonal variations at PLOR and BURAR seismic arrays and investigation of their influence on the detection capabilities of the two arrays (2015).

O2.1 Characterization of ambient seismic noise in urban environment.

Activity 2.1.1 Estimation of diurnal and seasonal variations at URS seismic array and investigation of their influence on the H/V ratios (2016).

O2.2 Identification of noise sources responsible for generation of seismic noise in high frequency domain as well as in microseisms domain.

Activity 2.2.1 Polarization analysis at individual seismic stations (2016).

Activity 2.2.2 F-k analysis and beamforming at BURAR, PLOR, SCP and URS seismic arrays (2016).

O3.1 Influence of sea level variations on microseisms

Activity 3.1.1 Correlation of the ambient seismic noise variations with sea level changes at seismic stations close to the Black Sea (2017).

O3.2 Influence of ambient noise characteristics on noise cross correlation functions and their use in monitoring small velocity changes in the crust.

Activity 3.2.1 Installation, configuration and use of MSNoise package (2017).

Activity 3.2.2 Estimation of the characteristics of noise cross correlation functions obtained at large scale (2017).

Activity 3.2.3 Estimation of the characteristics of noise cross correlation functions obtained in the Bucharest area (2017).

Activity 3.2.4 Monitoring velocity changes in Earth structure using ambient seismic noise (2017).
