Real-time Ground Shaking Maps (PGA distribution - cm/s2) and Peak Ground Rotations (PGR - mrad/s2) for the last 10 days. Events shown are those with (M ≥ 4.0) in Greece and broader area. Data (automatic locations) are derived from the Seismological Laboratory of the University of Athens. Algorithm is written in such a way to also monitor the automatic epicenter location corrections. Ground Shaking Maps are produced automatically without human intervention. Events have not been reviewed by seismologist. The algorithm is written and developed in MATLAB environment.
PGA was originally developed under the framework of GRECO-RISKS Hellenic Natural-Hazards-Risk-Management System of Systems and later improved by Sakkas (2016). Peak Ground Rotations (PGR) were developed in the framework of G. Sakkas PhD "Calculation and analysis of the seismic motion rotational components in Greece" (Sakkas 2016).
