Outline of Final Research Achievements

We investigated AE activities in deep gold mines in South Aftica, where many earthquakes are induced by mining. We made an AE-event catalog by using data obtained by more than 1-year observation, and found many interesting activities which have not been known in previous studies: steady AE activities on geological faults, very small repeating earthquakes, and AEs likely delineating macroscopic damage zone that newly emerged in front of the mining front.
