The Precise Point Positioning (PPP) analysis technique adapted for monitoring of high - rate coordinate variations from GPS observations is applied for detection of actual displacements related to moderate and light earthquakes. Two approaches are examined: kinematic PPP which is suitable for larger displacements and analysis of residuals from quasi-static PPP which is suitable for detection of min or earthquake related displacements. The potential and limits of the se used methods are documented on M 6.3 L’Aquila earthquake and M 4.3 Tatabanya earthquake. Our experiments proved the ability to measure dynamic seismic-related short-term coordinate variations at sub-centimetre level with PPP using GPS 1 Hz satellites observations.
