| Zusammenfassung |
| In this study the correlation between the monthly fluctuations of the water
level of the Aswan High Dam and monthly number of earthquakes from 1982 to
2010, which occurred in the surrounding area, was investigated. Our findings
reveal that significant correlation is present during the period 1982–1993
between water level and shallow seismicity (depth less than 15 km). The deep
seismicity (depth larger than 15 km) is significantly correlated with the
water level between January and April 1989. The time lag of the significant
maximal cross-correlation varies from 2–8~months for the shallow
seismicity, while it is around 7–8 months for the deep seismicity. These values
of the time lags could be in favour of the presence of two distinct
triggering mechanisms: one due to pore pressure diffusion and the other due
to fracture compaction (undrained response). |
