| Zusammenfassung |
| Most studies on the correlations between earthquakes and solid tides
mainly concluded the syzygies (i.e. new or full moons) of each lunar cycle
have more earthquakes than other days in the month. We show a correlation
between the aftershock sequence of the ML = 6.3 Christchurch, New Zealand,
earthquake and the diurnal solid tide. Ms ≥ 7 earthquakes worldwide since 1900 are more
likely to occur during the 0°, 90°, 180° or
270° phases (i.e. earthquake-prone phases) of
the semidiurnal solid earth tidal curve (M2). Thus, the
semidiurnal solid tides triggers earthquakes. However, the long-term
triggering effect of the lunar periodicity is uncertain. This proposal is
helpful in defining possible origin times of aftershocks several days after
a mainshock and can be used for warning of subsequent larger shocks. |
