Major achievements
Dr. Saeko Kita has established a unique approach that combines petrology and geology with seismic tomography as the mainstay of her work, and has established a strong presence in the field. She has achieved important results regarding the structure of the interior of the subducted oceanic plate and the mantle above it, and its relationship to earthquake occurrence. For example, she has pointed out the relationship between the geological features of the upper plate in the Hokkaido region and frequent occurrence of earthquakes beneath the Hidaka Mountains. The regional diversity of intraslab earthquakes was also discussed based on the change in effective strength of rocks due to dehydration reactions caused by temperature and pressure changes, Furthermore, she clarified the relationship between slow-slip events, seismic activity, and fluid pressure transfer, and proposed a new monitoring method for great earthquakes in subduction zones. In addition to these interdisciplinary research, she has been actively leading international collaborative research, providing research guidance to JICA trainees, and training future female researchers. Dr. Kita, who has pursued various activities while raising a child, deserves to be honored as a role model for female researchers.
