摘要

The cyclic migration of weak earthquakes (M ≥ 2.2) which occurred during the year prior to the October 15, 1996 (M = 4.9) Reggio Emilia earthquake is discussed in this paper. The onset of this migration was associated with the occurrence of the October 10, 1995 (M = 4.8) Lunigiana earthquake about 90 km southwest from the epicenter of the Reggio Emilia earthquake. At least three series of earthquakes migrating from the epicentral area of the Lunigiana earthquake in the northeast direction were observed. The migration of earthquakes of the first series terminated at a distance of about 30 km from the epicenter of the Reggio Emilia earthquake. The earthquake migration of the other two series halted at about 10 km from the Reggio Emilia epicenter. The average rate of earthquake migration was about 200-300 km/year, while the time of recurrence of the observed cycles varied from 68 to 178 days. Weak earthquakes migrated along the transversal fault zones and sometimes jumped from one fault to another. A correlation between the migrating earthquakes and tidal variations is analysed. We discuss the hypothesis that the analyzed area is in a state of stress approaching the limit of the long-term durability of crustal rocks and that the observed cyclic migration is a results of a combination of a more or less regular evolution of tectonic and tidal variations.
