Özet

Aim: Testing the precision of broadband displacements, combined from the strongest aspects of Global Positioning System (GPS) and seismometer data. Methods: Kalman filter and coherence have been used for computing broadband displacements and determining the dominant frequencies, respectively. Results: Determination of earthquake magnitude in high sensitivity in a short time. Estimation of moment magnitude from maximum P-wave displacement in the few seconds and high precision calculation of moment magnitude by solving fault geometry and slip values.
