| Zusammenfassung |
| The tidal changes of the barometric pressure in the area of Thessaloniki were studied by
analysing a sample of 21 years of hourly measurements. The resulted tidal parameters
(amplitude and phase difference) were considered as "mean values" of the
corresponding parameters for this long time period. Using these parameters,
barometric changes were computed and subtracted from the observations. Assuming that
the residuals might include local (in terms of time) information,the residual time
series was split in 21 blocks and a new analysis was performed for each block
separately. The 21 amplitude values computed for each tidal wave were considered
as the amplitude variation with respect to the correspondingmean value. An
observable correlation of the amplitude exalting of the most of the tidal waves
was found to Earthquakes of magnitude >4, occurred close to Thessaloniki in the
test period. |
