The problem in the campaign data for studying geodynamic processes

Mazzotti et al. (2005) have shown that by given certain assumptions about the pattern of crustal deformation in intra-plate environments, campaign GPS measurements over 6–9 years can provide useful constraints on the recurrence period and maximum magnitude of large earthquakes. However, major limitations associated with campaign GPS measurements are: (1) lack of resolution of short-term (less than a year) deformation episodes, (2) less accurate estimates of long term velocities (Henton et al., 2006). Further more, the discrete character of campaign GPS data prevents the direct estimation of the amplitude of different noise components.
